# RustySecp256k1

NIF library using `rustler` and a [pure Rust implementation of Secp256k1](https://github.com/paritytech/libsecp256k1).
This is not an exhaustive port of the library to Elixir but only meant to provide functionality for:

- Creating Public Key from Private Keys
- Decompressing Public Keys
- Performing point addition using Public Keys and Tweak Keys

For a complete libsecp256k1 implementation see [exthereum/libsecp256k1](https://github.com/exthereum/libsecp256k1) for a C-based NIF.
