| DES is being replaced by Rijndael, also known as AES, as the preferred |
| block ciper. <i>setupAESstate</i>, <i>aesCBCencrypt</i>, and <i>aesCBCdecrypt</i> implement |
| cipher block chaining encryption. <i>Keybytes</i> should be 16, 24, or |
| 32. The initialization vector <i>ivec</i> of <i>AESbsize</i> bytes should random |
| enough to be unlikely to be reused but |
| does not need to be cryptographically strongly unpredictable.<br> |
