v2.3.0

Compare Source

Security & constant-timeness

• Hardened constant-time execution from best-effort to actual guarantees: no measurable timing behavior on 200K samples. Scalar multiplication now uses secret-scalar blinding via CSPRNG, un-precomputed points now use a constant-time fixed-window multiply instead of variable-time fallbacks, and modular arithmetic helpers were hardened. New CT benchmarks track timing behavior.
• General hardening across all modules
• Fixes from the Trail of Bits review: recovered ECDSA signatures are now bound to their recovery id, non-canonical BLS signature encodings are rejected, Edwards <-> Montgomery conversion helpers were corrected, and FROST DKG round-2 retry handling was hardened.

X25519 hardening

It was possible to execute a remote timing attack on X25519, across many samples, and learn up to 4.036 bits of long-term private key. Other 247 bits were NOT affected.

The impact: mainly fingerprinting (recognition of key across deployments), NOT key recovery, NOT X25519 breakage. Maintainer was also not able to escalate to co-residency (SMT).

Reported and found by:

• George Stergiopoulos, Department of Informatics, Athens University of Economics and Business, Greece (geostergiop@aueb.gr)
• Constantinos Patsakis, Department of Informatics, University of Piraeus, 80 Karaoli & Dimitriou str., 18534 Piraeus, Greece (kpatsak@unipi.gr)

Performance

• ECDSA/EdDSA verification up to +32%, Weierstrass ECDH up to +19%, x25519 getPublicKey 2.7×
• BLS signatures 2x
• Init time (first getPublicKey or sign) reduced ~2x for ed25519, p256, p384, p521
• Also faster verification of recovered signatures, pairing tower / FFT / Pippenger optimizations, and joint-MSM paths in FROST and OPRF
• getPublicKey / sign got slower because we've decreased window size (W=8 => W=6) and hardened CT execution (see above). Long-running apps that prefer 2.2.0-level speed can restore it with one line: secp256k1.Point.BASE.precompute(8) (likewise for other curves).

Misc

• Smaller bundles: improved tree-shaking across modules
• Better error messages and type checks
• Upgrade noble-hashes to 2.3.0, with performance boost
• Reduce on-disk size 1831kb → 1548kb (-282kb) by disabling source maps (they became less relevant).

v2.2.0

Compare Source

  • This creates incompatibility of code between versions
  • Previously, it was hard to use and constantly emitted errors similar to TS2345
  • See typescript#62240 for more context
• Implement FROST threshold signatures from RFC 9591
• Fix compilation issues on TypeScript v6

(We're skipping v2.1, to align with other noble packages)

• package.json: specify exported submodules to ensure typescript autocompletion
• package.json: bump hashes to 2.0.1 with scrypt & pkg.json changes
• ed25519: export map_to_curve_elligator2_curve25519 #​211

New Contributors

• @​MegaManSec made their first contribution in #​212

GitHub Immutable Releases

This GH release does not include standalone noble-curves.js: use 2.0.0 for now, until we upgrade to newly added Immutable Releases

High-level

v2 massively simplifies internals, improves security, reduces bundle size and lays path for the future. To simplify upgrading, upgrade first to curves 1.9.x. It would show deprecations in vscode-like text editor.

• The package is now ESM-only. ESM can finally be loaded from common.js on node v20.19+
  • Node v20.19 is now the minimum required version
  • Package imports now work correctly in bundler-less environments, such as browsers
  • Reduces npm package size (traffic consumed): 354KB => 300KB
  • Reduces unpacked npm size (on-disk space): 2.1MB => 1.2MB
• Make bundle sizes smaller, compared to v1.x: -4KB for schnorr, -5.3KB for ristretto255, -9.4KB for x448
• .js extension must be used for all modules
  • Old: @noble/curves/ed25519
  • New: @noble/curves/ed25519.js
  • This simplifies working in browsers natively without transpilers

New features

• webcrypto: create friendly noble-like wrapper over built-in WebCrypto
• oprf: implement RFC 9497 OPRFs (oblivious pseudorandom functions)
  • We support p256, p384, p521, ristretto255 and decaf44
• weierstrass, edwards: add isValidSecretKey, isValidPublicKey
• misc: add Brainpool curves: brainpoolP256r1, brainpoolP384r1, brainpoolP512r1

Changes

• Most methods now expect Uint8Array, string hex inputs are prohibited
  • The change simplifies reasoning, improves security and reduces malleability
  • Point.fromHex now expects string-only hex inputs, use Point.fromBytes for Uint8Array
• Breaking changes of ECDSA (secp256k1, p256, p384...):
  • sign, verify: Switch to prehashed messages. Instead of
    messageHash, the methods now expect unhashed message.
    To bring back old behavior, use option {prehash: false}
  • sign, verify: Switch to lowS signatures by default.
    This change doesn't affect secp256k1, which has been using lowS since beginning.
    If you tested against specific sign / verify vectors, upgrading to v2 would fail, unless old behavior is brought back.
    To bring back old behavior, use option {lowS: false}
  • sign, verify: Switch to Uint8Array signatures (format: 'compact') by default.
  • verify: der format must be explicitly specified in {format: 'der'}.
    This reduces malleability
  • verify: prohibit Signature-instance signature. User must now always do
    signature.toBytes()
• Breaking changes of BLS signatures (bls12-381, bn254):
  • Move getPublicKey, sign, verify, signShortSignature etc into two new namespaces:
    bls.longSignatures (G1 pubkeys, G2 sigs) and bls.shortSignatures (G1 sigs, G2 pubkeys).
  • verifyBatch now expects array of inputs {message: ..., publicKey: ...}[]
• Curve changes:
  • Massively simplify curve creation, split it into point creation & sig generator creation
  • New methods are weierstrass() + ecdsa() / edwards() + eddsa()
  • weierstrass / edwards expect simplified curve params (Fp became p)
  • ecdsa / eddsa expect Point class and hash
  • Remove unnecessary Fn argument in pippenger
• modular changes:
  • Field#fromBytes() now validates elements to be in 0..order-1 range
• Upgrade typescript compilation env to ts5.9 and es2022
• Massively improve error messages, make them more descriptive

  • Point.fromPrivateKey() got removed, use Point.BASE.multiply() and Point.Fn.fromBytes(secretKey)

  • RistrettoPoint => ristretto255.Point, DecafPoiont => decaf44.Point

• Massive type renamings and improvements

Removed features

• Point#multiplyAndAddUnsafe, Point#hasEvenY
• CURVE property with all kinds of random stuff. Point.CURVE() now replaces it, but only provides
  curve parameters
• Remove pasta, bn254_weierstrass (NOT pairing-based bn254) curves
• Field.MASK
• utils.normPrivateKeyToScalar
