    $password = sha1($app_secret);

    $salt = substr(sha1(mt_rand()), 0, 4);
    $saltWithPassword = hash('sha256', $password . $salt);

    $encrypted = openssl_encrypt(
        "$data", 'aes-256-cbc', "$saltWithPassword", null, $iv
    );

    $msg_encrypted_bundle = "$iv:$salt:$encrypted";
    $hash_key = str_replace('/', '__', $msg_encrypted_bundle);

    return $hash_key;
