/**
|
||||
* Pure-PHP implementation of AES.
|
||||
*
|
||||
* Uses mcrypt, if available, and an internal implementation, otherwise.
|
||||
*
|
||||
* PHP versions 4 and 5
|
||||
*
|
||||
* If {@link Crypt_AES::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
|
||||
* {@link Crypt_AES::setKey() 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 {@link Crypt_Rijndael::setKey() 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. {@link Crypt_AES::setBlockLength() 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:
|
||||
* <code>
|
||||
* <?php
|
||||
* include('Crypt/AES.php');
|
||||
*
|
||||
* $aes = new Crypt_AES();
|
||||
*
|
||||
* $aes->setKey('abcdefghijklmnop');
|
||||
*
|
||||
* $size = 10 * 1024;
|
||||
* $plaintext = '';
|
||||
* for ($i = 0; $i < $size; $i++) {
|
||||
* $plaintext.= 'a';
|
||||
* }
|
||||
*
|
||||
* echo $aes->decrypt($aes->encrypt($plaintext));
|
||||
* ?>
|
||||
* </code>

|

* echo $rc4->encrypt($plaintext);
|

* </code>
|

*
|

* The solution is to enable the continuous buffer. Although this will resolve the above discrepancy, it creates
|

|

*
|
||||
* <code>
|

* $rc4->encrypt(substr($plaintext, 0, 8));

* decryption round when the continuous buffer is enabled. When it's disabled, they remain constant.
|

*
|
||||
* Put another way, when the continuous buffer is enabled, the state of the Crypt_DES() object changes after each
|
||||
* encryption / decryption round, whereas otherwise, it'd remain constant. For this reason, it's recommended that
|
||||
* continuous buffers not be used. They do offer better security and are, in fact, sometimes required (SSH uses them),
