Crypt_DES

# Procedural File: DES.php Source Location: /lib/3rdParty/phpseclib/Crypt/DES.php ## Classes: Crypt_DES Pure-PHP implementation of DES. ## Page Details: Pure-PHP implementation of DES. Uses mcrypt, if available, and an internal implementation, otherwise. PHP versions 4 and 5 Useful resources are as follows: Wikipedia: DES supplementary material FIPS 46-2 - (DES), Data JavaScript DES Example Here's a short example of how to use this library: <?php include('Crypt/DES.php'); $des = new Crypt_DES(); $des->setKey('abcdefgh'); $size = 10 * 1024; $plaintext = ''; for ($i = 0; $i < $size; $i++) { $plaintext.= 'a'; } echo $des->decrypt($des->encrypt($plaintext)); ?> LICENSE: Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
