| /** | ||||
|  * 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)); | ||||
|  * ?> | ||||

|  * Pure-PHP implementations of keyed-hash message authentication codes (HMACs) and various cryptographic hashing functions. | ||||

|  * 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} | ||||

|  * | ||||
|  * 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)); | ||||

| /** | ||||
|  * Pure-PHP implementation of Rijndael. | ||||
|  * | ||||
|  * Uses mcrypt, if available/possible, and an internal implementation, otherwise. | ||||
|  * | ||||
|  * PHP version 5 | ||||
|  * | ||||
|  * If {@link self::setBlockLength() setBlockLength()} isn't called, it'll be assumed to be 128 bits.  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. | ||||
|  * | ||||
|  * Not all Rijndael implementations may support 160-bits or 224-bits as the block length / key length.  mcrypt, for example, | ||||
|  * does not.  AES, itself, only supports block lengths of 128 and key lengths of 128, 192, and 256. | ||||
|  * {@link http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=10 Rijndael-ammended.pdf#page=10} defines the | ||||
|  * algorithm for block lengths of 192 and 256 but not for block lengths / key lengths of 160 and 224.  Indeed, 160 and 224 | ||||
|  * are first defined as valid key / block lengths in | ||||
|  * {@link http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=44 Rijndael-ammended.pdf#page=44}: | ||||
|  * Extensions: Other block and Cipher Key lengths. | ||||
|  * Note: Use of 160/224-bit Keys must be explicitly set by setKeyLength(160) respectively setKeyLength(224). | ||||
|  * | ||||
|  * {@internal The variable names are the same as those in | ||||
|  * {@link http://www.csrc.nist.gov/publications/fips/fips197/fips-197.pdf#page=10 fips-197.pdf#page=10}.}} | ||||
|  * | ||||
|  * Here's a short example of how to use this library: | ||||
|  * <code> | ||||
|  * <?php | ||||
|  *    include 'vendor/autoload.php'; | ||||
|  * | ||||
|  *    $rijndael = new \phpseclib\Crypt\Rijndael(); | ||||
|  * | ||||
|  *    $rijndael->setKey('abcdefghijklmnop'); | ||||
|  * | ||||
|  *    $size = 10 * 1024; | ||||
|  *    $plaintext = ''; | ||||
|  *    for ($i = 0; $i < $size; $i++) { | ||||
|  *        $plaintext.= 'a'; | ||||
|  *    } | ||||
|  * | ||||
|  *    echo $rijndael->decrypt($rijndael->encrypt($plaintext)); | ||||
