Et si vous avez déclaré un `response_model`, il sera toujours utilisé pour filtrer et convertir l'objet que vous avez renvoyé.

También puedes omitir el tipo de retorno. FastAPI usará el [`jsonable_encoder`](./encoder.md) para convertir los datos y enviarlos.

## Hachage de mot de passe { #password-hashing }

« Hachage » signifie convertir un contenu (un mot de passe dans ce cas) en une séquence d'octets (juste une chaîne) qui ressemble à du charabia.

Chaque fois que vous fournissez exactement le même contenu (exactement le même mot de passe), vous obtenez exactement le même charabia.

Mais vous ne pouvez pas convertir le charabia en sens inverse vers le mot de passe.

## Disable Convert Underscores { #disable-convert-underscores }

The same way as with regular header parameters, when you have underscore characters in the parameter names, they are **automatically converted to hyphens**.

For example, if you have a header parameter `save_data` in the code, the expected HTTP header will be `save-data`, and it will show up like that in the docs.

   * an IPv4 address or not.
   *
   * <p>IPv6 addresses are <b>coerced</b> to IPv4 addresses before being converted to integers.
   *
   * <p>As long as there are applications that assume that all IP addresses are IPv4 addresses and
   * can therefore be converted safely to integers (for whatever purpose) this function can be used
   * to handle IPv6 addresses as well until the application is suitably fixed.
