Elixir bindings for [secp256k1](https://github.com/bitcoin-core/secp256k1) library

## Installation

The package can be installed by adding `lib_secp256k1` to your list of dependencies in `mix.exs`:

```elixir

def deps do

  [

    {:lib_secp256k1, "~> 0.4.1"},

  ]

end

```

During the compilation the C library is cloned and build from source. If you are having problem

compiling the library please refer to the original repository.

The C code wrapping the library is also build during the compilation. I only tested it on Linux

machine so if you are having problem compiling it on Mac or Windows it is most likely related to

that. Please fill an issue but I don't have other systems available to me so don't expect me to

fix it anytime soon (contributions are welcome though :) ).

## Features

- [x] generate secure random seckey

- [x] derive pubkey and serialize it in compressed, uncompressed or xonly format

- [x] generate and validate ECDSA signatures

- [x] generate and validate Schnorr signatures

- [x] compute Diffie-Hellman secret
