Usage Usage
===== =====
Simple example:
local md5 = require 'md5' 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_hex = md5.sumhexa(message) -- returns a hex string
local md5_as_data = md5.sum(message) -- returns raw bytes 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())
