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"`.

### Tags com Enums

Se você tem uma grande aplicação, você pode acabar acumulando **várias tags**, e você gostaria de ter certeza de que você sempre usa a **mesma tag** para *operações de rota* relacionadas.

Nestes casos, pode fazer sentido armazenar as tags em um `Enum`.

    This is due to an issue of prefix based Matcher() function
    which was incorrectly matching prefix based on resource
    prefixes instead of exact match.
