+md5.lua [![Build Status](https://travis-ci.org/kikito/md5.lua.svg)](https://travis-ci.org/kikito/md5.lua)
+=========================================================================================================
+
+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](http://www.keplerproject.org/md5/), but it's done completely in Lua, with no dependencies on other libs or C files.
+
+Usage
+=====
+
+Simple example:
+
+    local md5 = require 'md5'
+
+    local md5_as_data  = md5.sum(message)       -- returns raw bytes
+    local md5_as_hex   = md5.sumhexa(message)   -- returns a hex string
+    local md5_as_hex2  = md5.tohex(md5_as_data) -- returns the same string as md5_as_hex
+
+Incremental example (for computing md5 of streams, or big files which have to be loaded in chunks - new since 1.1.0):
+
+    local m = md5.new()
+    m:update('some bytes')
+    m:update('some more bytes')
+    m:update('etc')
+    return md5.tohex(m:finish())
+
+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.
