Optimized C library for EC operations on curve secp256k1

An optimized C library for EC operations on curve secp256k1.

This library is a work in progress and is being used to research best practices. Use at your own risk.

Features

  • secp256k1 ECDSA signing/verification and key generation.
  • Adding/multiplying private/public keys.
  • Serialization/parsing of private keys, public keys, signatures.
  • Constant time, constant memory access signing and pubkey generation.
  • Derandomized DSA via RFC6979 or with a caller provided function.
  • Very efficient implementation.
