AES Encryption without Mcrypt library

https://github.com/ivantcholakov/gibberish-aes-php

This class tries ti use openssl_*() functions at first place, if they don't exist then uses mcrypt. If you want not to depend on mcrypt, your PHP version should be minimum 5.3.3.

Well, at least the name is approprate.

Seriously though, just upgrade to CI 3.0-dev, the new Encryption library in it can work without Mcrypt.
