php two way encrypt decrypt

function encryptor($action, $string) {
	$output = FALSE;
	$encrypt_method = "AES-256-CBC";
	$secret_key = 'SecretKeyWord';
	$secret_iv  = 'SecretIV@123GKrQp';
	// hash
	$key = hash('sha256', $secret_key);
	// iv - encrypt method AES-256-CBC expects 16 bytes - else you will get a warning
	$iv = substr(hash('sha256', $secret_iv), 0, 16);
	//do the encryption given text/string/number
	if ($action == 'encrypt') {
		$output = openssl_encrypt($string, $encrypt_method, $key, 0, $iv);
		$output = base64_encode($output);
	} elseif ($action == 'decrypt') {
		//decrypt the given text/string/number
		$output = openssl_decrypt(base64_decode($string), $encrypt_method, $key, 0, $iv);
	}
	return $output;
}

function encrypt($data) {
	return urlencode(self::encryptor('encrypt', self::sanitize($data)));
}

function decrypt($data) {
	return self::encryptor('decrypt', urldecode(self::sanitize($data)));
}
// Now you can just call encrypt($string) or decrypt($string)
?>
