 *
 * Provides secure storage of passwords and other sensitive credentials
 * using AES-GCM encryption with PBKDF2 key derivation.
 *
 * Features:
 * - Encrypts credentials at rest using AES-256-GCM
 * - Uses PBKDF2 for key derivation from master password
 * - Secure wiping of sensitive data
 * - Thread-safe operations
 * - Protection against timing attacks

# WebSockets { #websockets }

Você pode usar [WebSockets](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API) com **FastAPI**.

## Instale `websockets` { #install-websockets }

Garanta que você criou um [ambiente virtual](../virtual-environments.md), o ativou e instalou o `websockets` (uma biblioteca Python que facilita o uso do protocolo "WebSocket"):

<div class="termy">

```console
$ pip install websockets

---> 100%
```

Para esos casos, puedes usar el `jsonable_encoder` para convertir tus datos antes de pasarlos a un response:

/// note | Detalles técnicos

También podrías usar `from starlette.responses import JSONResponse`.

## Manipulando codificações de corpo de requisição personalizadas { #handling-custom-request-body-encodings }

Vamos ver como usar uma subclasse personalizada de `Request` para descomprimir requisições gzip.

E uma subclasse de `APIRoute` para usar essa classe de requisição personalizada.

### Criar uma classe `GzipRequest` personalizada { #create-a-custom-gziprequest-class }
