XXTEA encryption/decryption module for Lua

lua-xxtea encrypts/decrypts binary strings with 128 bit keys (16 bytes long binary strings). When a key is less than 16 bytes long, it is assumed to have trailing zeroes ('\0').

local xxtea = require 'xxtea'

local str1 = 'Hello, world!'
local key = 'abc123'

local str2 = xxtea.encrypt(str1, key)
local str3 = xxtea.decrypt(str2, key)

assert(str1 ~= str2)
assert(str1 == str3)
