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);
}
?>
