Certificate Authorities
-----------------------

The above example uses a self-signed certificate. This is convenient for testing but not
representative of real-world HTTPS deployment. To get closer to that we can use `HeldCertificate`
to generate a trusted root certificate, an intermediate certificate, and a server certificate.
We use `certificateAuthority(int)` to create certificates that can sign other certificates. The

Um dasselbe Problem zu lösen, ist es wahrscheinlich viel einfacher, den `body` in einem benutzerdefinierten Handler für `RequestValidationError` zu verwenden ([Fehlerbehandlung](../tutorial/handling-errors.md#use-the-requestvalidationerror-body)).

        As there are too many questions, I'll have to discard and close the incomplete ones. That will allow me (and others) to focus on helping people like you that follow the whole process and help us help you. 🤓

`secrets.compare_digest()` benötigt `bytes` oder einen `str`, welcher nur ASCII-Zeichen (solche der englischen Sprache) enthalten darf, das bedeutet, dass es nicht mit Zeichen wie `á`, wie in `Sebastián`, funktionieren würde.

Um dies zu lösen, konvertieren wir zunächst den `username` und das `password` in UTF-8-codierte `bytes`.
