Para lidar com isso, primeiramente nós convertemos o `username` e o `password` para `bytes`, codificando-os com UTF-8.

Então nós podemos utilizar o `secrets.compare_digest()` para garantir que o `credentials.username` é `"stanleyjobson"`, e que o `credentials.password` é `"swordfish"`.

Isso seria parecido com:

```Python

	opts.Port = 14223
	opts.Username = "testminio"
	opts.Password = "miniotest"
	s := natsserver.RunServer(&opts)
	defer s.Shutdown()

	clientConfig := &NATSArgs{
		Enable: true,
		Address: xnet.Host{
			Name:      "localhost",
			Port:      (xnet.Port(opts.Port)),
			IsPortSet: true,
		},
		Subject:  "test",
		Username: opts.Username,
		Password: opts.Password,
	}

	con, err := clientConfig.connectNats()

	Topic                string         `json:"topic"`
	QoS                  byte           `json:"qos"`
	User                 string         `json:"username"`
	Password             string         `json:"password"`
	MaxReconnectInterval time.Duration  `json:"reconnectInterval"`
	KeepAlive            time.Duration  `json:"keepAliveInterval"`
	RootCAs              *x509.CertPool `json:"-"`

# OAuth2 с паролем (и хешированием), Bearer с JWT-токенами { #oauth2-with-password-and-hashing-bearer-with-jwt-tokens }

Теперь, когда у нас определен процесс обеспечения безопасности, давайте сделаем приложение действительно безопасным, используя токены <abbr title="JSON Web Tokens – веб‑токены JSON">JWT</abbr> и безопасное хеширование паролей.

Этот код можно реально использовать в своем приложении, сохранять хэши паролей в базе данных и т.д.
