tetsy-secp256k1

tetsy-secp256k1 is a wrapper around libsecp256k1, a C library by Peter Wuille for producing ECDSA signatures using the SECG curve secp256k1. It is a fork of rust-secp256k1.

This library

  • exposes type-safe Rust bindings for all libsecp256k1 functions
  • implements key generation
  • implements deterministic nonce generation via RFC6979
  • implements many unit tests, adding to those already present in libsecp256k1
  • makes no allocations (except in unit tests) for efficiency and use in freestanding implementations
