Changing the Initialization vector?

[NoMan2000]

I made a pull request to remove the call to mcrypt that's still in the file. It can be replaced with an openSSL call, your code will still work.

   // Build an initialisation vector	
   // Replacing all mcrypt calls
    // $iv = mcrypt_create_iv($this->iv_num_bytes, MCRYPT_DEV_URANDOM);
   
    // Build an initialisation vector
    $iv = openssl_random_pseudo_bytes($this->iv_num_bytes, $isStrongCrypto);
    if (!$isStrongCrypto) {
        throw new \Exception("Not a strong key");
    }
