Sensitive data

Encryption

To enable secure storage of sensitive data, you must define an encryption key in your wp-config.php file. This key is used to encrypt and decrypt the sensitive data and should be kept secret at all times. Make sure the key is a cryptographically random 32-character hexadecimal string.

Add the following line to your wp-config.php:

// OWC | GravityForms ZGW – Encryption Key
define('OWC_GRAVITYFORMS_ZGW_ENCRYPTION_KEY', 'your-unique-32-character-key');

Generate a secure key

Generate a valid key using PHP: php bin2hex(random_bytes(16));
