Ruby LibECP

Ruby LibECP is a wrapper around LibECP, an elliptic-curve cryptography library for producing and verifying ECDSA signatures.

Use the gem in a project managed with Bundler adding it into Gemfile:

gem "cf-ruby-libecp"

This gem is a native extension gem. The native library will be compiled on your platform automatically at install time.

The required packages to build the gem are:

• GMP, a multiprecision arithmetic library.
• GCC, a compiler for C, C++, Java, Fortan and other program code that can be used in Unix.
