/**
* an implementation of the AES (Rijndael), from FIPS-197.
* <p/>
* For further details see: <a href="http://csrc.nist.gov/encryption/aes/">http://csrc.nist.gov/encryption/aes/</a>.
* <p/>
* This implementation is based on optimizations from Dr. Brian Gladman's paper and C code at
* <a href="http://fp.gladman.plus.com/cryptography_technology/rijndael/">http://fp.gladman.plus.com/cryptography_technology/rijndael/</a>
* <p/>
* There are three levels of tradeoff of speed vs memory
* Because java has no preprocessor, they are written as three separate classes from which to choose
* <p/>
* The fastest uses 8Kbytes of static tables to precompute round calculations, 4 256 word tables for encryption
* and 4 for decryption.
* <p/>
* The middle performance version uses only one 256 word table for each, for a total of 2Kbytes,
* adding 12 rotate operations per round to compute the values contained in the other tables from
* the contents of the first
* <p/>
* The slowest version uses no static tables at all and computes the values in each round
* <p/>
* This file contains the fast version with 8Kbytes of static tables for round precomputation
