      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)
