Minimal, zero-dependency JS implementation of elliptic curve cryptography.
- Short Weierstrass curve with ECDSA signatures
- Twisted Edwards curve with EdDSA signatures
- Montgomery curve for ECDH key agreement
- Short Weierstrass, Edwards, Montgomery curves
- ECDSA, EdDSA, Schnorr, BLS signature schemes
- ECDH key agreement
- [hash to curve](https://datatracker.ietf.org/doc/draft-irtf-cfrg-hash-to-curve/) algorithms for encoding or hashing an arbitrary string to a point on an elliptic curve
- Auditable, [fast](#speed)
- 🔻 Helps JS bundlers with lack of entry point, ensures small size of your app
- 🔍 Unique tests ensure correctness. Wycheproof vectors included
To keep the package minimal, no curve definitions are provided out-of-box. Use `micro-curve-definitions` module:
- It provides P192, P224, P256, P384, P521, secp256k1, stark curve, bn254, pasta (pallas/vesta) short weierstrass curves
- It also provides ed25519 and ed448 twisted edwards curves
- Main reason for separate package is the fact hashing library (like `@noble/hashes`) is required for full functionality
- It provides P192, P224, P256, P384, P521, secp256k1, stark, bn254, pasta (pallas/vesta), ed25519, ed448 & bls12-381 curves
- Main reason for separate package is the fact hashing library (like @noble/hashes) is required for full functionality
- We may reconsider merging packages in future, when a stable version would be ready
Future plans:
- hash to curve standard
- point indistinguishability
- pairings
The goal for the near future is to update previous packages
([secp256k1](https://github.com/paulmillr/noble-secp256k1),
[ed25519](https://github.com/paulmillr/noble-ed25519),
[bls12-381](https://github.com/paulmillr/noble-bls12-381)) with lean UMD builds based on noble-curves. This would improve compatibility & allow having one codebase for everything.
### This library belongs to _noble_ crypto
