Implementation of the general encryption algorithm AES.
Since this algorithm is implemented in pure Ruby, it is not very fast. Therefore the FastAES class based on OpenSSL should be used when possible.
For reference: This implementation is about 5000 times slower when decrypting and about 1800 times slower when encrypting than the FastAES version.
This implementation is using AES in Cipher Block Chaining (CBC) mode.
