Not sure if it is a good idea to do encryption in pure Lua - of course
you CAN do it, but IMHO it is better to "leave it to the experts" and
use existing cryptography libraries, like OpenSSL (which even come with
cryptography hardware support). It is available in Lua through luacrypto
(http://github.com/mkottman/luacrypto - my fork which enables
cryptography routines)
