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