following repository contains an [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\n \"VerifiableCredential\",\n \"PermanentResidentCard\"\n ],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\n \"PermanentResident\",\n \"Person\"\n ],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\":

{\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n \n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\n \"PermanentResidentCard\",\n \"VerifiableCredential\"\n ],\n \"description\": \"Government of Example Permanent

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\n \"VerifiableCredential\",\n \"PermanentResidentCard\"\n ],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\n \"PermanentResident\",\n \"Person\"\n ],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n \n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\n \"PermanentResidentCard\",\n \"VerifiableCredential\"\n ],\n \"description\": \"Government of Example Permanent

[BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from

@mattrglobal/jsonld-signatures-bbs\n```\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\n \"VerifiableCredential\",\n \"PermanentResidentCard\"\n ],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\n \"PermanentResident\",\n \"Person\"\n ],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n \n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\n \"PermanentResidentCard\",\n \"VerifiableCredential\"\n ],\n \"description\": \"Government of Example Permanent

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\n \"VerifiableCredential\",\n

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n \n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\":

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\n \"VerifiableCredential\",\n \"PermanentResidentCard\"\n ],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\n \"PermanentResident\",\n \"Person\"\n ],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n \n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\n \"PermanentResidentCard\",\n \"VerifiableCredential\"\n ],\n \"description\": \"Government of Example Permanent

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\n \"VerifiableCredential\",\n \"PermanentResidentCard\"\n ],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\n \"PermanentResident\",\n \"Person\"\n ],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n \n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\n \"PermanentResidentCard\",\n \"VerifiableCredential\"\n ],\n \"description\": \"Government of Example Permanent

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"PermanentResidentCard\", \"VerifiableCredential\"],\n \"description\": \"Government of Example Permanent Resident

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\":

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\":

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"PermanentResidentCard\", \"VerifiableCredential\"],\n \"description\": \"Government of Example Permanent Resident

jsonld-signatures-bbs\n\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"PermanentResidentCard\", \"VerifiableCredential\"],\n \"description\": \"Government of Example Permanent Resident

jsonld-signatures-bbs\n\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"PermanentResidentCard\", \"VerifiableCredential\"],\n \"description\": \"Government of Example Permanent Resident

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\":

\"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"PermanentResidentCard\", \"VerifiableCredential\"],\n \"description\": \"Government of Example Permanent Resident

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"PermanentResidentCard\", \"VerifiableCredential\"],\n \"description\": \"Government of Example Permanent Resident

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"PermanentResidentCard\", \"VerifiableCredential\"],\n \"description\": \"Government of Example Permanent Resident

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"PermanentResidentCard\", \"VerifiableCredential\"],\n \"description\": \"Government of Example Permanent Resident

jsonld-signatures-bbs\n\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"PermanentResidentCard\", \"VerifiableCredential\"],\n \"description\": \"Government of Example Permanent Resident

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://eprint.iacr.org/2009/095.pdf), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BBSSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\":

\"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"PermanentResidentCard\", \"VerifiableCredential\"],\n \"description\": \"Government of Example Permanent Resident

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"PermanentResidentCard\", \"VerifiableCredential\"],\n \"description\": \"Government of Example Permanent Resident

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"PermanentResidentCard\", \"VerifiableCredential\"],\n \"description\": \"Government of Example Permanent Resident

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"PermanentResidentCard\", \"VerifiableCredential\"],\n \"description\": \"Government of Example Permanent Resident

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"PermanentResidentCard\", \"VerifiableCredential\"],\n \"description\": \"Government of Example Permanent Resident

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"PermanentResidentCard\", \"VerifiableCredential\"],\n \"description\": \"Government of Example Permanent Resident

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"signature\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"PermanentResidentCard\", \"VerifiableCredential\"],\n \"description\": \"Government of Example Permanent Resident

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\"\n ],\n \"type\":

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future. See [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) for more details.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

\"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\n**Note** At this time this project is limited to working in [node](nodejs.org) environments because the underlying cryptographic implementation is supplied by [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures), however we are targeting support for other parts of the JS/TS ecosystem in the near future. See [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) for more details.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\":

\"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

\"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\":

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n

\"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\":

\"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n

\"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n

\"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3c-ccg.github.io/ldp-bbs2020/context/v1\"\n ],\n \"id\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n

\"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\":

\"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\":

\"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\":

\"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\":

\"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\":

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

repository is the home to a performant multi-message digital signature algorithm implementation which supports\nderiving zero knowledge proofs that enable selective disclosure from the originally signed message set.\n\n[BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures) are a digital signature algorithm originally born from\nthe work on [Short group signatures](https://crypto.stanford.edu/~xb/crypto04a/groupsigs.pdf) by Boneh, Boyen, and\nShachum which was later improved on in\n[Constant-Size Dynamic k-TAA](http://web.cs.iastate.edu/~wzhang/teach-552/ReadingList/552-14.pdf) as BBS+ and touched on\nagain in section 4.3 in\n[Anonymous Attestation Using the Strong Diffie Hellman Assumption Revisited ](https://www.researchgate.net/publication/306347781_Anonymous_Attestation_Using_the_Strong_Diffie_Hellman_Assumption_Revisited).\n\n[BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures) require a\n[pairing-friendly curve](https://tools.ietf.org/html/draft-irtf-cfrg-pairing-friendly-curves-03), this library includes\nsupport for [BLS12-381](https://tools.ietf.org/html/draft-irtf-cfrg-pairing-friendly-curves-03#section-2.4).\n\n[BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures) allow for multi-message signing whilst producing a\nsingle output signature. With a BBS signature, a [proof of knowledge](https://en.wikipedia.org/wiki/Proof_of_knowledge)\nbased proof can be produced where only some of the originally signed messages are revealed at the discretion of the\nprover.\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/node-bbs-signatures\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/node-bbs-signatures\n```\n\n## Usage\n\nSee the [sample](./sample) directory for a runnable demo.\n\nThe following is a short sample on how to use the API\n\n```typescript\nimport {\n generateBls12381G2KeyPair,\n blsSign,\n blsVerify,\n blsCreateProof,\n blsVerifyProof,\n} from \"@mattrglobal/node-bbs-signatures\";\n\n//Generate a new key pair\nconst keyPair = await generateBls12381G2KeyPair();\n\n//Set of messages we wish to sign\nconst messages = [Uint8Array.from(Buffer.from(\"message1\", \"utf-8\")), Uint8Array.from(Buffer.from(\"message2\", \"utf-8\"))];\n\n//Create the signature\nconst signature = await blsSign({\n keyPair,\n messages: messages,\n});\n\n//Verify the signature\nconst isVerified = await blsVerify({\n publicKey: keyPair.publicKey,\n messages: messages,\n signature,\n});\n\n//Derive a proof from the signature revealing the first message\nconst proof = await blsCreateProof({\n signature,\n publicKey: keyPair.publicKey,\n messages,\n nonce: Uint8Array.from(Buffer.from(\"nonce\", \"utf8\")),\n revealed: [0],\n});\n\n//Verify the created proof\nconst isProofVerified = await blsVerifyProof({\n proof,\n publicKey: keyPair.publicKey,\n messages: messages.slice(0, 1),\n nonce: Uint8Array.from(Buffer.from(\"nonce\", \"utf8\")),\n});\n```\n\n## Element Size\n\nWithin a digital signature there are several elements for which it is useful to know the size, the following table\noutlines the general equation for calculating element sizes in relation to BBS+ signatures as it is dependent on the\npairing friendly curve used.\n\n| Element | Size Equation |\n| ----------- | ------------------------------------ |\n| Private Key | F |\n| Public Key | G2 |\n| Signature | G1 + 2\\*F |\n| Proof | 5*G1 + (4 + no_of_hidden_messages)*F |\n\n- `F` A field element\n- `G1` A point in the field of G1\n- `G2` A point in the field of G2\n- `no_of_hidden_messages` The number of the hidden messages\n\nThis library includes specific support for BLS12-381 keys with BBS+ signatures and hence gives rise to the following\nconcrete sizes\n\n| Element | Size with BLS12-381 |\n| ----------- | --------------------------------------- |\n| Private Key | 32 Bytes |\n| Public Key | 96 Bytes |\n| Signature | 112 Bytes |\n| Proof | 368 + (no_of_hidden_messages)\\*32 Bytes |\n\n## Getting started as a contributor\n\nThe following describes how to get started as a contributor to this project\n\n### Prerequisites\n\nThe following is a list of dependencies you must install to build and contribute to this project\n\n- [Yarn](https://yarnpkg.com/)\n- [Rust](https://www.rust-lang.org/)\n\nFor more details see our [contribution guidelines](./docs/CONTRIBUTING.md)\n\n#### Install\n\nTo install the package dependencies run:\n\n```\nyarn install --frozen-lockfile\n```\n\n#### Build\n\nTo build the project run:\n\n```\nyarn build\n```\n\n#### Test\n\nTo run the test in the project run:\n\n```\nyarn test\n```\n\n#### Benchmark\n\nTo benchmark the implementation locally run:\n\n```\nyarn benchmark\n```\n\n## Dependencies\n\nThis library uses the [bbs](https://crates.io/crates/bbs) rust crate for the implementation of BBS+ signatures and\nBLS12-381 which is then wrapped and exposed in javascript/typescript using\n[neon-bindings](https://github.com/neon-bindings/neon).\n\n## Security Policy\n\nPlease see our [security policy](./SECURITY.md) for additional details about responsible disclosure of security related\nissues.\n\n---\n\n

repository is the home to a performant multi-message digital signature algorithm implementation which supports\nderiving zero knowledge proofs that enable selective disclosure from the originally signed message set.\n\n[BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec) are a digital signature algorithm originally born from the work on\n[Short group signatures](https://crypto.stanford.edu/~xb/crypto04a/groupsigs.pdf) by Boneh, Boyen, and Shachum which was\nlater improved on in [Constant-Size Dynamic

](https://www.researchgate.net/publication/306347781_Anonymous_Attestation_Using_the_Strong_Diffie_Hellman_Assumption_Revisited).\n\nBBS+ signatures require a\n[pairing-friendly curve](https://tools.ietf.org/html/draft-irtf-cfrg-pairing-friendly-curves-03), this library includes\nsupport for [BLS12-381](https://tools.ietf.org/html/draft-irtf-cfrg-pairing-friendly-curves-03#section-2.4).\n\nBBS+ Signatures allow for multi-message signing whilst producing a single output signature.

The order of selection is the following.\n\n1. If in a node js based environment and the optional dependency of [@mattrglobal/node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) is installed use this.\n2. If in an environment that supports [Web Assembly](https://webassembly.org/) use this.\n\n**Note** Please refer to running the benchmarks below where you can compare these different implementations, the differences are very notable.\n\n**Note** To force the usage of a particular environment set the `BBS_SIGNATURES_MODE` environment variable to one of the following values\n\n- `NODE_JS_MODULE` - Use native node module, ensure [@mattrglobal/node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) is installed\n- `WASM` - Use the wasm module\n\n**Note** Previous releases of this library supported an asm.js compilation for usage in react native environments, however this has been deprecated due to performance issues.\n\n## Usage\n\nSee the [sample](./sample) directory for a runnable demo's.\n\nThe following is a short sample on how to use the API\n\n```typescript\nimport {\n generateBls12381G2KeyPair,\n blsSign,\n blsVerify,\n blsCreateProof,\n blsVerifyProof,\n} from \"@mattrglobal/bbs-signatures\";\n\n//Generate a new key pair\nconst keyPair = await generateBls12381G2KeyPair();\n\n//Set of messages we wish to sign\nconst messages = [\n Uint8Array.from(Buffer.from(\"message1\", \"utf-8\")),\n Uint8Array.from(Buffer.from(\"message2\", \"utf-8\")),\n];\n\n//Create the signature\nconst signature = await blsSign({\n keyPair,\n messages: messages,\n});\n\n//Verify the signature\nconst isVerified = await blsVerify({\n publicKey: keyPair.publicKey,\n messages: messages,\n signature,\n});\n\n//Derive a proof from the signature revealing the first message\nconst proof = await blsCreateProof({\n signature,\n publicKey: keyPair.publicKey,\n messages,\n nonce: Uint8Array.from(Buffer.from(\"nonce\", \"utf8\")),\n revealed: [0],\n});\n\n//Verify the created proof\nconst isProofVerified = await blsVerifyProof({\n proof,\n publicKey: keyPair.publicKey,\n messages: messages.slice(0, 1),\n nonce: Uint8Array.from(Buffer.from(\"nonce\", \"utf8\")),\n});\n```\n\n## Element Size\n\nWithin a digital signature there are several elements for which it is useful to know the size, the following table\noutlines the general equation for calculating element sizes in relation to BBS+ signatures as it is dependent on the\npairing friendly curve used.\n\n| Element | Size Equation |\n| ----------- | ------------------------------------ |\n| Private Key | F |\n| Public Key | G2 |\n| Signature | G1 + 2\\*F |\n| Proof | 5*G1 + (4 + no_of_hidden_messages)*F |\n\n- `F` A field element\n- `G1` A point in the field of G1\n- `G2` A point in the field of G2\n- `no_of_hidden_messages` The number of the hidden messages\n\nThis library includes specific support for BLS12-381 keys with BBS+ signatures and hence gives rise to the following\nconcrete sizes\n\n| Element | Size with BLS12-381 |\n| ----------- | --------------------------------------- |\n| Private Key | 32 Bytes |\n| Public Key | 96 Bytes |\n| Signature | 112 Bytes |\n| Proof | 368 + (no_of_hidden_messages)\\*32 Bytes |\n\n## Getting started as a contributor\n\nThe following describes how to get started as a contributor

Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\":

\"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n

\"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\":

\"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\":

\"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

jsonld-signatures-bbs\n\n![npm-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs)\n![npm-unstable-version](https://badgen.net/npm/v/@mattrglobal/jsonld-signatures-bbs/unstable)\n![push-master](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-master/badge.svg)\n![push-release](https://github.com/mattrglobal/jsonld-signatures-bbs/workflows/push-release/badge.svg)\n![codecov](https://codecov.io/gh/mattrglobal/jsonld-signatures-bbs/branch/master/graph/badge.svg)\n\nThe following repository contains a [linked data proof](https://w3c-ccg.github.io/ld-proofs/) implementation for creating [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec)\nusing [BLS12-381](https://tools.ietf.org/id/draft-yonezawa-pairing-friendly-curves-00.html#rfc.section.2.4) key pairs.\n\nDue to the properties of a [BBS+ Signatures](https://github.com/mattrglobal/bbs-signatures-spec), [zero knowledge proof](https://en.wikipedia.org/wiki/Zero-knowledge_proof) can be derived from the signature, where-by the party generating the proof can elect to selectively disclose statements from the originally signed payload.\n\nThis library is runnable in browser and Node.js through the [WASM](https://webassembly.org/) based crypto implementation provided by [bbs-signatures](https://github.com/mattrglobal/bbs-signatures). Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"issuer\": \"did:example:489398593\",\n \"identifier\": \"83627465\",\n \"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\": \"jx2VhjyZqUT91e2OhzweJA7G2u2UvmiDtIfmr+wUWNHWno+UOAh0FaNpM8Br+5j2JBkH981/nO1I7/9PFaRrng6NXu7vzDroKtuyj6nHGkMmGq4OMmBzIqRnG3ybin/Sxmu5YwqOxPMRsWH3H+2wSA==\"\n }\n}\n```\n\nWhereby a zero knowledge proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n

Note [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) also has an optional dependency on [node-bbs-signatures](https://github.com/mattrglobal/node-bbs-signatures) which can be used when running in [Node.JS](https://nodejs.org/en/) environments to obtain better performance. For environments that do not feature [WASM](https://webassembly.org/) support such as [react native](https://reactnative.dev/), [bbs-signatures](https://github.com/mattrglobal/bbs-signatures) includes an automatic roll back to an [asm.js](http://asmjs.org/) version but note however the performance difference between [asm.js](http://asmjs.org/) and [WASM](https://webassembly.org/) is significant, for those inclined there are runnable benchmarks in [bbs-signatures](https://github.com/mattrglobal/bbs-signatures).\n\n## Getting started\n\nTo use this package within your project simply run\n\n```\nnpm install @mattrglobal/jsonld-signatures-bbs\n```\n\nOr with [Yarn](https://yarnpkg.com/)\n\n```\nyarn add @mattrglobal/jsonld-signatures-bbs\n```\n\n## Sample\n\nSee the [sample](./sample) directory for a runnable demo.\n\n## Examples\n\nThe following is an example of a signed JSON-LD document featuring a `BbsBlsSignature2020` type signature.\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\":

\"name\": \"Permanent Resident Card\",\n \"description\": \"Government of Example Permanent Resident Card.\",\n \"issuanceDate\": \"2019-12-03T12:19:52Z\",\n \"expirationDate\": \"2029-12-03T12:19:52Z\",\n \"credentialSubject\": {\n \"id\": \"did:example:b34ca6cd37bbf23\",\n \"type\": [\"PermanentResident\", \"Person\"],\n \"givenName\": \"JOHN\",\n \"familyName\": \"SMITH\",\n \"gender\": \"Male\",\n \"image\": \"data:image/png;base64,iVBORw0KGgokJggg==\",\n \"residentSince\": \"2015-01-01\",\n \"lprCategory\": \"C09\",\n \"lprNumber\": \"999-999-999\",\n \"commuterClassification\": \"C1\",\n \"birthCountry\": \"Bahamas\",\n \"birthDate\": \"1958-07-17\"\n },\n \"proof\": {\n \"type\": \"BbsBlsSignature2020\",\n \"created\": \"2020-04-26T04:21:07Z\",\n \"verificationMethod\": \"did:example:489398593#test\",\n \"proofPurpose\": \"assertionMethod\",\n \"proofValue\":

proof disclosing only `givenName`, `familyName` and `gender` can be derived, from the above assertion using the following as the reveal document\nwhich is a [JSON-LD frame](https://www.w3.org/TR/json-ld11-framing/).\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"type\": [\"VerifiableCredential\", \"PermanentResidentCard\"],\n \"credentialSubject\": {\n \"type\": [\"PermanentResident\", \"Person\"],\n \"@explicit\": true,\n \"givenName\": {},\n \"familyName\": {},\n \"gender\": {}\n }\n}\n```\n\nThat gives rise to the output zero knowledge proof\n\n```json\n{\n \"@context\": [\n \"https://www.w3.org/2018/credentials/v1\",\n \"https://w3id.org/citizenship/v1\",\n \"https://w3id.org/security/bbs/v1\"\n ],\n \"id\": \"https://issuer.oidp.uscis.gov/credentials/83627465\",\n
