* Pure-PHP implementation of DES.
|
|
|
5 |
*
|
|
|
6 |
* Uses mcrypt, if available, and an internal implementation, otherwise.
|

7 |
*
|
|
|
8 |
* PHP version 5
|
|
|

* Here's a short example of how to use this library:
|
|
|
17 |
* <code>
|
|
|
18 |
* <?php
|
|
|
19 |
* include 'vendor/autoload.php';
|
|
|
20 |
*
|
|
|
21 |
* $des = new \phpseclib\Crypt\DES();
|
|
|
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>
