These implementations are designed for use in zero-knowledge proofs and other cryptographic applications.\n\n> Note: These circuits not audited and not yet recommended for production use.\n\n## Setup\n\n```sh\n$ git clone https://github.com/crema-labs/ecdsa-p384-circom\n$ cd ecdsa-p384-circom\n$ yarn\n```\n\n## Project Structure\n\nIn this repository, we are using [Circomkit](https://github.com/erhant/circomkit) to test some example circuits using Mocha. The circuits and the statements that they prove are as follows:\n\n## Circuits\n\n1. [`ecdsa.circom`](https://github.com/crema-labs/ecdsa-p384-circom/blob/main/circuits/ecdsa.circom): Implements the ECDSA signature verification and private key to public key conversion for the P-384 curve.\n - [ECDSAPrivToPub](https://github.com/crema-labs/ecdsa-p384-circom/blob/main/circuits/ecdsa.circom#L13) - Converts a private key to a public key in P-384.\n - [ECDSAVerifyNoPubkeyCheck](https://github.com/crema-labs/ecdsa-p384-circom/blob/main/circuits/ecdsa.circom#L131) - Verifies an ECDSA signature for a given message and public key.\n2. [`p384.circom`](https://github.com/crema-labs/ecdsa-p384-circom/blob/main/circuits/p384.circom): Implements the basic operations for the P-384 curve.\n - [P384AddUnequal](https://github.com/crema-labs/ecdsa-p384-circom/blob/main/circuits/p384.circom#L14) - Adds two unequal points on the P-384 curve.\n - [P384Double](https://github.com/crema-labs/ecdsa-p384-circom/blob/main/circuits/p384.circom#L34) - Doubles a point on the P-384 curve.\n - [P384ScalarMult](https://github.com/crema-labs/ecdsa-p384-circom/blob/main/circuits/p384.circom#L56) - Multiplies a point on the P-384 curve by a scalar.\n\n### Testing\n\nYou can use the following commands to test the circuits:\n\n```sh\n# test everything\nyarn test\n\n# test a specific circuit\nyarn test -g \n```\n\n## Benchmarks\nAll tests were performed on a MacBook Pro M1 2020 with 8GB RAM. \n| Operation | Constraints | Time (ms) |\n| ------------------------------ | ----------- | --------- |\n| ECDSA Signature Verification | 4,429,227 | 4,21,394 |\n| ECDSA Point Addition (Unequal) | 4,352 | 850 |\n| ECDSA Point Addition (Equal) | 6,000 | 573 |\n| ECDSA Scalar Multiplication | 3,977,848 | 4,20,964 |\n\n\n# Credits\nThis project was made possible thanks to the support of [ZK Email](https://github.com/zkemail) and [OpenPassport](https://github.com/zk-passport) for the grant.\n# Acknowledgments\n\nThis project builds upon the excellent work of the [circom-ecdsa-p256](https://github.com/privacy-scaling-explorations/circom-ecdsa-p256) by PSE and [circom-ecdsa](https://github.com/0xPARC/circom-ecdsa) by 0xPARC. We are grateful for their contributions to implementation of ECDSA in Circom, which formed the foundation for our work.\n\n## Contribution\n\nFeel free to contribute to this repository by creating issues or pull requests. We are open to any suggestions or improvements.\n","readmeFilename":"README.md"}
