k256 0.9.3

secp256k1 elliptic curve library written in pure Rust with support for ECDSA signing/verification (including Ethereum-style signatures with public-key recovery), Elliptic Curve Diffie-Hellman (ECDH), and general purpose secp256k1 curve arithmetic useful for implementing arbitrary group-based protocols.
