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.

Build and test

To make lib/libmcl.a and test, run

make test

To make sample programs, run

make sample

If clang is not installed, then

make USE_LLVM=0

Build for 32-bit Linux

Build openssl and gmp for 32-bit mode and install

cd mcl
make BIT=32 CFLAGS_USER="-I <lib32>/include" LDFLAGS_USER="-L <lib32>/lib -Wl,-rpath,<lib32>/lib"

Build for 64-bit Windows

open mcl.sln and build or if you have msbuild.exe

msbuild /p:Configuration=Release
