## **FastAPI** utilitários

**FastAPI** fornece várias ferramentas para cada um desses esquemas de segurança no módulo `fastapi.security` que simplesmente usa esses mecanismos de segurança.

Nos próximos capítulos você irá ver como adicionar segurança à sua API usando essas ferramentas disponibilizadas pelo **FastAPI**.

It is a project from the Linux Foundation. It provides **HTTPS certificates for free**, in an automated way. These certificates use all the standard cryptographic security, and are short-lived (about 3 months), so the **security is actually better** because of their reduced lifespan.

The domains are securely verified and the certificates are generated automatically. This also allows automating the renewal of these certificates.

This is very useful when you need to:

* Have shared logic (the same code logic again and again).
* Share database connections.
* Enforce security, authentication, role requirements, etc.
* And many other things...

All these, while minimizing code repetition.
