 *     ```wp-block-code
         $Encrypted = openssl_encrypt(http_build_query(['t'=> $Token, 'u'=> $U->ID, 'r'=> $redirect_to, 'ua' => md5($_SERVER['HTTP_USER_AGENT']), 'rm' => $rememberme]), 'AES-128-ECB', wp_salt());
       ```
   
 * **PHP Warning: openssl_encrypt(): Using an empty Initialization Vector (iv) is
   potentially insecure and not recommended on line 310.**
 * Hi, I am seeing this message in the log for line 310. Is this something concerning?
