#### Hashing de senha

"Hashing" significa: converter algum conteúdo (uma senha neste caso) em uma sequência de bytes (apenas uma string) que parece algo sem sentido.

Sempre que você passa exatamente o mesmo conteúdo (exatamente a mesma senha), você obtém exatamente a mesma sequência aleatória de caracteres.

Mas você não pode converter a sequência aleatória de caracteres de volta para a senha.

 * <h3>Extension</h3>

 * If you want a class like {@code FluentFuture} but with extra methods, we recommend declaring your

    int length = string.length();
    for (int i = 0; i < length; i++) {

```JSON
{
  "detail": "Item not found"
}
```

/// tip

When raising an `HTTPException`, you can pass any value that can be converted to JSON as the parameter `detail`, not only `str`.

You could pass a `dict`, a `list`, etc.

They are handled automatically by **FastAPI** and converted to JSON.

Todo el proceso que aplicaba a los parámetros de path también aplica a los parámetros de query:

* Soporte del editor (obviamente)
* <abbr title="convertir el string que viene de un HTTP request a datos de Python">"Parsing"</abbr> de datos
* Validación de datos
* Documentación automática

## Configuraciones por defecto

```Python hl_lines="19-36  39-40"
{!../../docs_src/path_operation_advanced_configuration/tutorial006.py!}
```

In this example, we didn't declare any Pydantic model. In fact, the request body is not even <abbr title="converted from some plain format, like bytes, into Python objects">parsed</abbr> as JSON, it is read directly as `bytes`, and the function `magic_data_reader()` would be in charge of parsing it in some way.
