Для больших ответов возвращать `Response` напрямую значительно быстрее, чем возвращать словарь.

Это потому, что по умолчанию FastAPI проверяет каждый элемент внутри и убеждается, что он сериализуем в JSON, используя тот же [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}, объяснённый в руководстве. Это позволяет возвращать **произвольные объекты**, например модели из базы данных.

For example, you could use it to read and verify passwords generated by another system (like Django) but hash any new passwords with a different algorithm like Argon2 or Bcrypt.

And be compatible with all of them at the same time.

///

Create a utility function to hash a password coming from the user.

And another utility to verify if a received password matches the hash stored.

Esto se debe a que, por defecto, FastAPI inspeccionará cada elemento dentro y se asegurará de que sea serializable como JSON, usando el mismo [Codificador Compatible con JSON](../tutorial/encoder.md){.internal-link target=_blank} explicado en el tutorial. Esto es lo que te permite devolver **objetos arbitrarios**, por ejemplo, modelos de bases de datos.

These environment variables can only handle text strings, as they are external to Python and have to be compatible with other programs and the rest of the system (and even with different operating systems, as Linux, Windows, macOS).
