md5.lua Build Status

This pure-Lua module computes md5 in Lua 5.1, Lua 5.2 and LuaJIT, using native bit-manipulation libraries when available, and falling back to table-based manipulation of integers in 5.1.

It implements md5.sum and md5.sumhex like the kernel project md5 package, 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.
