/**
|
||||
* Pure-PHP implementation of AES.
|
||||
*
|
||||
* Uses mcrypt, if available/possible, and an internal implementation, otherwise.
|
||||
*
|
||||
* PHP version 5
|
||||
*
|
||||
* NOTE: Since AES.php is (for compatibility and phpseclib-historical reasons) virtually
|
||||
* just a wrapper to Rijndael.php you may consider using Rijndael.php instead of
|
||||
* to save one include_once().
|
||||
*
|
||||
* If {@link self::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
|
||||
* {@link self::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 192-bits and 192 bits will be the key length until {@link self::setKey() setKey()}
|
||||
* is called, again, at which point, it'll be recalculated.
|
||||
*
|
||||
* Since \phpseclib\Crypt\AES extends \phpseclib\Crypt\Rijndael, some functions are available to be called that, in the context of AES, don't
|
||||
* make a whole lot of sense. {@link self::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 'vendor/autoload.php';
|
||||
*
|
||||
* $aes = new \phpseclib\Crypt\AES();
|
||||
*
|
||||
* $aes->setKey('abcdefghijklmnop');
|
||||
*
|
||||
* $size = 10 * 1024;
|
||||
* $plaintext = '';
|
||||
* for ($i = 0; $i < $size; $i++) {
|
||||
* $plaintext.= 'a';
|
||||
* }
|
||||
*
|
||||
* echo $aes->decrypt($aes->encrypt($plaintext));
|
||||
* ?>
|
||||
* </code>

/**

* Pure-PHP implementation of RC4.
|

*
|
||||
* Uses mcrypt, if available, and an internal implementation, otherwise.
|
||||
*
|
||||
* PHP version 5
|
||||
*
|
||||
* Useful resources are as follows:
|
||||
*
|
||||
* - {@link http://www.mozilla.org/projects/security/pki/nss/draft-kaukonen-cipher-arcfour-03.txt ARCFOUR Algorithm}
|

* - {@link http://en.wikipedia.org/wiki/RC4 - Wikipedia: RC4}
|
||||
*
|
||||
* RC4 is also known as ARCFOUR or ARC4. The reason is elaborated upon at Wikipedia. This class is named RC4 and not
|
||||
* ARCFOUR or ARC4 because RC4 is how it is referred to in the SSH1 specification.
|
||||
*
|
||||
* Here's a short example of how to use this library:
|
||||
* <code>
|
||||
* <?php
|
||||
* include 'vendor/autoload.php';
|
||||
*
|
||||
* $rc4 = new \phpseclib\Crypt\RC4();
|
||||
*
|
||||
* $rc4->setKey('abcdefgh');
|
||||
*
|
||||
* $size = 10 * 1024;
|
||||
* $plaintext = '';
|
||||
* for ($i = 0; $i < $size; $i++) {
|
||||
* $plaintext.= 'a';
|
||||
* }
|
||||
*
|
||||
* echo $rc4->decrypt($rc4->encrypt($plaintext));
|

* ?>

|

* Extensions: Other block and Cipher Key lengths.
|

|
||||
* encryption / decryption round, whereas otherwise, it'd remain constant. For this reason, it's recommended that

/**
|
||||
* Pure-PHP implementation of Twofish.
|
||||
*
|
||||
* Uses mcrypt, if available, and an internal implementation, otherwise.
|
||||
*
|
||||
* PHP version 5
|
||||
*
|
||||
* Useful resources are as follows:
|
||||
*
|
||||
* - {@link http://en.wikipedia.org/wiki/Twofish Wikipedia description of Twofish}
|
||||
*
|
||||
* Here's a short example of how to use this library:
|
||||
* <code>
|
||||
* <?php
|
||||
* include 'vendor/autoload.php';
|
||||
*
|
||||
* $twofish = new \phpseclib\Crypt\Twofish();
|
||||
*
|
||||
* $twofish->setKey('12345678901234567890123456789012');
|
||||
*
|
||||
* $plaintext = str_repeat('a', 1024);
|
||||
*
|
||||
* echo $twofish->decrypt($twofish->encrypt($plaintext));
|
||||
* ?>
|
||||
* </code>
