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.
