• Update noble-hashes to 1.7.1
• Improve docs

Full Changelog: 1.8.0...1.8.1

1.8.0

• The package is now available on JSR.
• Use isolatedDeclarations typescript option, which massively simplifies documentation auto-gen, and more
  • Check out JSR page for one example
• Add tons of comments everywhere to improve autocompletion, LLM code gen, and basic code understanding.
• modular: fix isLE logic bug, reverse mapHashToField
• Upgrade hashes to v1.7.0

Full Changelog: 1.7.0...1.8.0

1.7.0

• curve: add wnafCachedUnsafe() and precomputeMSMUnsafe().
  • new methods speed-up MSM for cases when inputs are public
  • edwards, weierstrass: switch multiplyUnsafe to new wnaf methods
• modular: crash on non-prime P in sqrt instead of looping
  • do not precompute sqrtP on initializaton, delay until first call
• weierstrass: add support for strict format option in verify, choose between compact and der
• bls: Export some types to simplify building custom curves
• utils: Improve isBytes speed
• improve compatibility with parsers and minifiers
• Upgrade hashes to v1.6.0

1.6.0

What's Changed

• weierstrass, edwards: add multi-scalar-multiplication using Pippenger algorithm
• DER encoding: improve edge cases. Fixes p521 signatures
• hash-to-curve: add more type checks
• Export abstract/tower for pairing-friendly curves
• Add support for node.js v14
• Upgrade hashes to v1.5.0

Full Changelog: 1.5.0...1.6.0

1.5.0

• Implement bn254 (aka alt_bn128) pairings, compatible with EVM and ZEC
  • Point serialization is not implemented (but can be added in user-space), because there is no standard way of doing it. Check out README
• Refactor range checks for private keys and signatures, simplify them
• Add memoization for toAffine and assertValidity, to speed-up BLS
• Make all points immutable and frozen to improve security

• ed448: Fix x448 private keys, to be 56 bytes, not 57
• weierstrass: fix weierstrassPoints missing CURVE object by @secure12 in #92
• utils:
  • hexToBytes: speed-up 6x, improve error formatting by @arobsn in #83
  • isBytes: improve reliability in bad environments such as jsdom
  • concatBytes: improve safety by early-checking the type
  • equalBytes: make constant-time
• Bump noble-hashes to 1.3.3
• Bump typescript version used to build the package to 5.3.2
