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>
