This fork keeps the same API and fixes what was broken underneath: repeated references, browser/node divergence, the prototype-graph walk that halved performance.\n\n```bash\nnpm install @bybrave/object-hash2\n```\n\n```js\n// CommonJS — drop-in\nconst hash = require(\"@bybrave/object-hash2\");\n\n// ESM\nimport hash from \"@bybrave/object-hash2\";\n\nhash({ foo: \"bar\" }); // 'a02...'\nhash({ foo: \"bar\" }, { algorithm: \"md5\" }); // '132...'\nhash.keys({ foo: \"bar\" }); // keys only\n```\n\nSame options as the original: `algorithm`, `encoding`, `excludeValues`, `excludeKeys`, `replacer`, `respectType`, `respectFunctionProperties`, `respectFunctionNames`, `unorderedArrays`, `unorderedSets`, `unorderedObjects`, `ignoreUnknown` — see the [original documentation](https://github.com/puleos/object-hash#hashvalue-options).\n\n## What's different from object-hash 3.0.0\n\n| Change | Original issue |\n|---|---|\n| Repeated (non-circular) references hash like copies: `hash([a, a]) === hash([[1,2], [1,2]])`. Real cycles are still detected | [#78](https://github.com/puleos/object-hash/issues/78) |\n| Identical hashes in Node.js and the browser, byte for byte — the browser build runs the same serializer with own md5/sha1/sha256 (fuzz-checked against `node:crypto`) | [#62](https://github.com/puleos/object-hash/issues/62) |\n| Browser bundle 4.5 KB gzipped instead of ~10 KB (no more `crypto-browserify`) | [#91](https://github.com/puleos/object-hash/issues/91) |\n| ~2x faster with default options: the `respectType` prototype-graph walk replaced with a compact type marker | perf reports |\n| `respectType` no longer reads `__proto__`/`constructor`/`prototype` of foreign objects — no more crashes on classes with throwing prototype getters (Mongo `ObjectID` & co) | [#49](https://github.com/puleos/object-hash/issues/49) |\n| `Buffer`, `Uint8Array`, `Uint8ClampedArray`, `ArrayBuffer` and `DataView` with the same bytes hash the same | — |\n| `DataView` hashes by content (the original hashed every `DataView` to the same constant) | — |\n| TypeScript definitions shipped with the package (compatible with `@types/object-hash`) | — |\n| ESM entry (`import hash from \"@bybrave/object-hash2\"`) + `exports` map | — |\n| Build: esbuild instead of gulp + browserify; CI on Node 18/20/22; zero runtime dependencies (as before) | — |\n\n## Hash compatibility with 3.x — read before upgrading\n\nThis is a major release and **some hashes change**. If you persist hashes (cache keys, deduplication), regenerate them on upgrade — the original did the same in its 2.x → 3.x major.\n\nUnchanged (byte-identical to 3.0.0, pinned by tests):\n\n- primitives, strings, dates, regexps, URLs, errors, symbols, bigints, numeric typed arrays — with any options;\n- **everything hashed with `respectType: false`**, as long as the value has no repeated references and no binary types listed below.\n\nChanged:\n\n- default-options hashes of values containing objects or functions (`respectType: true` used to serialize the whole prototype graph — that walk is now a compact marker);\n- values with repeated references (that's the [#78](https://github.com/puleos/object-hash/issues/78) fix);\n- `Buffer` / `Uint8Array` / `Uint8ClampedArray` / `ArrayBuffer` / `DataView` values (unified byte serialization, identical across platforms);\n- hashes produced in the browser (they now match Node.js — that's the point).\n\n## Compatibility\n\n- API is unchanged — drop-in replacement for `object-hash`: `hash()`, `hash.sha1()`, `hash.keys()`, `hash.MD5()`, `hash.keysMD5()`, `hash.writeToStream()`.\n- Node.js ≥ 18; modern browsers. Browser algorithms: `md5`, `sha1`, `sha256` (+ `passthrough`); in Node.js everything from `crypto.getHashes()`.\n- Browser `
