mcrypt_encrypt fails to initialise
- by mixkat
I am trying to encrypt some data in PHP using the Rijndael cipher in CBC mode with a 256bit key but for some reason I get the following error message:
mcrypt_encrypt() Module initialization failed
My code:
$hashKey = hash('sha256',$key);
$iv = hash('sha256',$hashKey);
// ------Cipher-------------key-------------Data-------------Mode---------IV--
$encryptedQuestion = base64_encode(mcrypt_encrypt('MCRYPT_RIJNDAEL_256', $hashKey , $_POST['question'], MCRYPT_MODE_CBC, $iv));
Can anyone see whats wrong with this?
