Add (post quantum) end-to-end encryption

Twenty is European, open source, and self-hostable, which is simply amazing!

However, the last thing that’s missing is end-to-end encryption to fully protect all data in the best way possible. Ideally, the encryption algorithm would already be post-quantum, as this is becoming the new industry standard.

Definitely a great idea
