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())
|
||
