In the chapters about security, there are utility functions that are implemented in this same way.

If you understood all this, you already know how those utility tools for security work underneath.

# À propos des versions de FastAPI { #about-fastapi-versions }

**FastAPI** est déjà utilisé en production dans de nombreuses applications et de nombreux systèmes. Et la couverture de tests est maintenue à 100 %. Mais son développement avance toujours rapidement.

De nouvelles fonctionnalités sont ajoutées fréquemment, des bogues sont corrigés régulièrement et le code s'améliore continuellement.
