1.9.6

• edwards: expose nBitLength, nByteLength
• Experimental CurveLengths interface: rename secret, public to secretKey, publicKey
• Point precomputes: initialize calculation earlier, within weierstrass() method (still lazy, waits for first call)
• bls: new internal tower from v2

Full Changelog: 1.9.5...1.9.6

Full Changelog: 1.9.4...1.9.5

1.9.4

• Add more deprecations for the upcoming v2

Full Changelog: 1.9.3...1.9.4

1.9.3

The release contains bugfixes and a few improvements which pave the way for upcoming v2.0.

There are lots of renamings and API adjustments; but all old code would work as-is. The code would visually flagged as "deprecated" (using jsdoc flag) in typescript-supported code environments, which makes it easy to upgrade to new versions.

• Rename *privateKey to *secretKey everywhere for consistency with post-quantum and non-noble libraries
• Add keygen method to curves which creates both secret and public keys
• weierstrass: make endomorphism generic and work for all Koblitz curves
• weierstrass: add fromBytes and toBytes to Signature, deprecate fromDER, fromCompact, toDERRawBytes, toCompactRawBytes
• edwards: move edwardsToMontgomery into utils.toMontgomery
• decaf, ristretto: new interface which makes it more similar to other Points
• ed448: add ED448_TORSION_GROUP
• curve: add curve.info interface to all curves for better interop.
• curve: change public wNAF API
• modular: add sqrt9mod16
• hash-to-curve: move all hashers into _hasher props. E.g. secp256k1_hasher
• test: Add ACVP test vectors

Sensitive code changes

• wNAF: mostly renamings
• Field bound validation: for scalars (Fn) and curve fields (Fp)

Full Changelog: 1.9.2...1.9.3

Full Changelog: 1.9.0...1.9.1

1.9.0

The release contains bugfixes and a few improvements which pave the way for upcoming v2.0.

• Modules are now available with .js extension
  • Old: @noble/curves/ed25519
  • New: @noble/curves/ed25519.js
  • Old path is still available
  • This simplifies working in browsers natively without transpilers
• poseidon: add support for sponge, grain LFSR
• p256, p384, p521: merge into new "nist" module
• weierstrass: prohibit y=0 when initializing
• hash-to-curve: use inv0 everywhere to ensure ZERO elements are returned in exceptional cases
• modular: improve sqrt logic (tonelliShanks, legendre)
• modular: fix FpInvertBatch creating arrays with holes instead of arrays with undefined
• pasta: deprecate curves
• update noble-hashes to 1.8.0

Full Changelog: 1.8.2...1.9.0

1.8.2

• Important: this release adjusts wNAF scalar multiplication logic
  • The adjustment is small (deduplication), but wNAF is sensitive code handling private keys
  • Verify the change yourself #184
• edwards: (ed25519, ed448) always use complete formula in add()
• edwards: (ed25519, ed448) ban points with z=0 (zero points have z=1)
• ed25519: use slower, but more precise CURVE.a definition
• weierstrass: freeze Signature on creation
• weierstrass: Fix curve in Palemoon browser #176
• hash-to-curve: throw better error for 0 in mapToCurve
• tower: fix wrong Fp12 fields type
• misc: new module. Contains jubjub and babyjubjub.
• utils: use built-in Uint8Array toHex / fromHex when available. Gives 13x speed-up on 256b arrays, 20x speed-up on 32kb arrays

Other changes

• Update noble-hashes to 1.7.2
• Reduce standalone file build size by 0.5kb
• Standalone build files are now attested in CI. Check out README for verification guide
