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.
- 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.
