note 71452 added to function.mcrypt-encrypt

And two more similar functions for encrypting and decrypting
cookies:

<?php

function encryptCookie($value){
   if(!$value){return false;}
   $key = 'The Line Secret Key';
   $text = $value;
   $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256,
MCRYPT_MODE_ECB);
   $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);
   $crypttext = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key,
$text, MCRYPT_MODE_ECB, $iv);
   return trim(base64_encode($crypttext)); //encode for
cookie
}

function decryptCookie($value){
   if(!$value){return false;}
   $key = 'The Line Secret Key';
   $crypttext = base64_decode($value); //decode cookie
   $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256,
MCRYPT_MODE_ECB);
   $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);
   $decrypttext = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $key,
$crypttext, MCRYPT_MODE_ECB, $iv);
   return trim($decrypttext);
}

?>
