/**
* Pure-PHP implementation of AES.
*
* Uses mcrypt, if available/possible, and an internal implementation, otherwise.
*
* PHP versions 4 and 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 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 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 '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));
* ?>

/**
* Pure-PHP implementations of keyed-hash message authentication codes (HMACs) and various cryptographic hashing functions.
*
* Uses hash() or mhash() if available and an internal implementation, otherwise. Currently supports the following:
*
* md2, md5, md5-96, sha1, sha1-96, sha256, sha256-96, sha384, and sha512, sha512-96
*
* If {@link self::setKey() setKey()} is called, {@link self::hash() hash()} will return the HMAC as opposed to
* the hash. If no valid algorithm is provided, sha1 will be used.
*
* PHP versions 4 and 5
*
* {@internal The variable names are the same as those in
* {@link http://tools.ietf.org/html/rfc2104#section-2 RFC2104}.}}
*
* Here's a short example of how to use this library:
* <code>
* <?php
* include 'Crypt/Hash.php';
*
* $hash = new Crypt_Hash('sha1');
*
* $hash->setKey('abcdefg');
*
* echo base64_encode($hash->hash('abcdefg'));
* ?>

* $rc4->setKey('abcdefgh');
*
* $size = 10 * 1024;
