                      mcrypt_enc_get_supported_key_sizes

   (PHP 4 >= 4.0.2)
   mcrypt_enc_get_supported_key_sizes -- Returns an array with the
   supported keysizes of the opened algorithm

Description

   array mcrypt_enc_get_supported_key_sizes ( resource td)

   Returns an array with the key sizes supported by the algorithm
   specified by the encryption descriptor. If it returns an empty array
   then all key sizes between 1 and mcrypt_enc_get_key_size() are
   supported by the algorithm.

   Example 1. mcrypt_enc_get_supported_key_sizes() example
   <?php
       $td = mcrypt_module_open('rijndael-256', '', 'ecb', '');
       var_dump(mcrypt_enc_get_supported_key_sizes($td));
   ?>

   This will print:
array(3) {
  [0]=>
  int(16)
  [1]=>
  int(24)
  [2]=>
  int(32)
}
