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