secp256k1rb

This is a Ruby binding for Bitcoin Core's secp256k1 library.

Add this line to your application's Gemfile:

gem 'secp256k1rb', require: 'secp256k1'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install secp256k1rb

To use this library, you need to specify the path of the secp256k1 shared library in environment variable SECP256K1_LIB_PATH, e.g: $ export SECP256K1_LIB_PATH=/var/local/lib/libsecp256k1.so.

Note: This library also implements the recovery module, so you must have built the secp256k1 library with the --enable-module-recovery option.

By including the Secp256k1 module, you can use the features provided by the libsepc256k1 library. For example:

require 'secp256k1'

include Secp256k1
