Classes:

Crypt_TripleDES
Pure-PHP implementation of Triple DES.


Page Details:

Pure-PHP implementation of Triple DES.

Uses mcrypt, if available, and an internal implementation, otherwise. Operates in the EDE3 mode (encrypt-decrypt-encrypt).

PHP versions 4 and 5

Here's a short example of how to use this library:

  1.  <?php
  2.     include('Crypt/TripleDES.php');
  3.  
  4.     $des new Crypt_TripleDES();
  5.  
  6.     $des->setKey('abcdefghijklmnopqrstuvwx');
  7.  
  8.     $size 10 1024;
  9.     $plaintext '';
  10.     for ($i 0$i $size$i++{
  11.         $plaintext.= 'a';
  12.     }
  13.  
  14.     echo $des->decrypt($des->encrypt($plaintext));
  15.  ?>
