mcrypt is removed from php7.2. can not use in PHP 7.2. i have created new function and added in common helper.

if (!function_exists('mcrypt_create_iv')) {
    function mcrypt_create_iv($length) {
        return openssl_random_pseudo_bytes($length, NULL);
    }
}

might be helpful to other users.

This polyfill is useful for backwards compatibility w/ mcrypt on PHP 7.3:
