   2  * AES (Rijndael) cipher
   3  *
   4  * Modifications to public domain implementation:
   5  * - support only 128-bit keys
   6  * - cleanup
   7  * - use C pre-processor to make it easier to change S table access
   8  * - added option (AES_SMALL_TABLES) for reducing code size by about 8 kB at
   9  *   cost of reduced throughput (quite small difference on Pentium 4,
  10  *   10-25% when using -O1 or -O2 optimization)
