Upstream README

rust-secp256k1

rust-secp256k1 is a wrapper around libsecp256k1, a C library by Pieter Wuille for producing ECDSA signatures using the SECG curve 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

Contributing

Contributions to this library are welcome. A few guidelines:

• Any breaking changes must have an accompanied entry in CHANGELOG.md
• No new dependencies, please.
• No crypto should be implemented in Rust, with the possible exception of hash functions. Cryptographic contributions should be directed upstream to libsecp256k1.
• This library should always compile with any combination of features on Rust 1.14, which is the currently shipping compiler on Debian.
