Crypt_AES
Pure-PHP implementation of AES.
Page Details:
Pure-PHP implementation of AES.
Uses mcrypt, if available, and an internal implementation, otherwise. PHP versions 4 and 5 If Crypt_AES::setKeyLength() isn't called, it'll be calculated from Crypt_AES::setKey(). ie. if the key is 128-bits, the key length will be 128-bits. If it's 136-bits it'll be null-padded to 160-bits and 160 bits will be the key length until setKey() is called, again, at which point, it'll be recalculated. Since Crypt_AES extends Crypt_Rijndael, some functions are available to be called that, in the context of AES, don't make a whole lot of sense. setBlockLength(), for instance. Calling that function, however possible, won't do anything (AES has a fixed block length whereas Rijndael has a variable one). Here's a short example of how to use this library: <?php
include('Crypt/AES.php');
$aes->setKey('abcdefghijklmnop');
$size = 10 * 1024;
$plaintext = '';
for ($i = 0; $i < $size; $i++) {
$plaintext.= 'a';
}
echo $aes->decrypt($aes->encrypt($plaintext));
?>
