# mcl

A class library of finite field and elliptic curve.

# Abstract

This is a library to make a protocol for elliptic curve cryptography.

# Installation Requirements

Create a working directory (e.g., work) and clone the following repositories.

       mkdir work
       cd work
       git clone git://github.com/herumi/xbyak.git
       git clone git://github.com/herumi/cybozulib.git
       git clone git://github.com/herumi/cybozulib_ext.git

* Cybozulib_ext is a prerequisite for running OpenSSL and GMP on VC (Visual C++).
* Xbyak is a prerequisite for optimizing the operations in the finite field on Intel CPUs.
* OpenSSL and libgmp-dev are available via apt-get (or other similar commands) if using Linux.
