Changelog

• 0.2.1 (2024-12-18)

  • Adds 'serialize_point' for compressed-format serialization of secp256k1 points.

• 0.2.0 (2024-11-08)

  • Adds wNAF ("w-ary non-adjacent form") scalar multiplication, as well as fast 'sign' and 'verify' variants for Schnorr and ECDSA (disambiguated by a trailing apostrophe) that make use of it.

    Each wNAF-powered function requires a 'Context' consisting of precomputed secp256k1 generator multiples; one can be gotten via 'precompute'.

    Note that the non-wNAF-powered sign and verify functions have incurred a slight performance decrease (on the order of tens to hundreds of microseconds) as a result.

  • Adds 'parse_sig' for parsing compact signatures.

  • Adds a dependency on the 'primitive' library (already transitively required via 'ppad-hmac-drbg').

• 0.1.0 (2024-10-19)

  • Initial release, supporting public key derivation and Schnorr & ECDSA signatures on secp256k1.
