||
| 4 | * Pure-PHP implementation of DES. |
||
| 5 | * |
||
| 6 | * Uses mcrypt, if available, and an internal implementation, otherwise. |
||
| 7 | * |
||
| 8 | * PHP version 5 |
||
| 9 | * |
||
| 10 | * Useful resources are as follows: |
||
| 11 | * |
||
| 12 | * - {@link http://en.wikipedia.org/wiki/DES_supplementary_material Wikipedia: DES supplementary material} |
||
| 13 | * - {@link http://www.itl.nist.gov/fipspubs/fip46-2.htm FIPS 46-2 - (DES), Data Encryption Standard} |
||
| 14 | * - {@link http://www.cs.eku.edu/faculty/styer/460/Encrypt/JS-DES.html JavaScript DES Example} |
||
| 15 | * |
||
| 16 | * Here's a short example of how to use this library: |
||
| 17 | * <code> |
||
| 18 | * <?php |
||
| 19 | * include 'vendor/autoload.php'; |
||
| 20 | * |
||
| 21 | * $des = new \phpseclib3\Crypt\DES('ctr'); |
||
| 22 | * |
||
| 23 | * $des->setKey('abcdefgh'); |
||
| 24 | * |
||
| 25 | * $size = 10 * 1024; |
||
| 26 | * $plaintext = ''; |
||
| 27 | * for ($i = 0; $i < $size; $i++) { |
||
| 28 | * $plaintext.= 'a'; |
||
| 29 | * } |
||
| 30 | * |
||
| 31 | * echo $des->decrypt($des->encrypt($plaintext)); |
||
| 32 | * ?> |
||
| 33 | * </code> |
