md5.lua
========

This pure-Lua module computes md5 in Lua 5.1.

It implements md5.sum and md5.sumhex like the [kernel project md5 package](http://www.keplerproject.org/md5/), but it's done completely in Lua, with no dependencies on other libs or C files.

Usage
=====

    local md5 = require 'md5'

    local md5_as_hex   = md5.sumhexa(message)   -- returns a hex string
    local md5_as_data  = md5.sum(message)     -- returns raw bytes

Credits
=======

This is a cleanup of an implementation by Adam Baldwin - https://gist.github.com/evilpacket/3647908

Which in turn was a mix of the bitwise lib, http://luaforge.net/projects/bit/ by hanzhao (`abrash_han - at - hotmail.com`),
and http://equi4.com/md5/md5calc.lua, by Equi 4 Software.
