Si vous avez lu et compris tout cela, vous en savez maintenant bien plus sur les environnements virtuels que beaucoup de développeurs. 🤓

Néanmoins, c’est toujours à vous de faire appliquer ces scopes, ou toute autre exigence de sécurité/autorisation, selon vos besoins, dans votre code.

Dans de nombreux cas, OAuth2 avec scopes peut être excessif.

Mais si vous savez que vous en avez besoin, ou si vous êtes curieux, continuez à lire.

## 12. Future Enhancements

1. **Directory Leases**: Extend lease support for directories
2. **Lease Key Persistence**: Save lease keys for reconnection
3. **Parent-Child Relationships**: Implement hierarchical leases
4. **Lease Sharing**: Support lease sharing across handles

Now that we have all the security flow, let's make the application actually secure, using <abbr title="JSON Web Tokens">JWT</abbr> tokens and secure password hashing.

This code is something you can actually use in your application, save the password hashes in your database, etc.

We are going to start from where we left in the previous chapter and increment it.

## About JWT { #about-jwt }

JWT means "JSON Web Tokens".

				t.Fatalf("invalid signature 0x%x", binary.BigEndian.Uint32(v.header.Signature[:]))
