`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`.
