Mas por enquanto, vamos verificar essas importantes **ideias conceituais**. Esses conceitos também se aplicam a qualquer outro tipo de API da web. 💡

## Segurança - HTTPS

No [capítulo anterior sobre HTTPS](https.md){.internal-link target=_blank} aprendemos como o HTTPS fornece criptografia para sua API.

Também vimos que o HTTPS normalmente é fornecido por um componente **externo** ao seu servidor de aplicativos, um **Proxy de terminação TLS**.

 Если у вас более старая версия, будут ошибки при попытке использовать `Annotated`.

Убедитесь, что вы [Обновили FastAPI версию](../../deployment/versions.md#fastapi_2){.internal-link target=_blank} до, как минимум 0.95.1, перед тем как использовать `Annotated`.
