Not at all. There are younger people around that think/believe if they communicate via Signal, Telegram or whatever, their communication is someone secure. It is not. The better look for another and better way. Even GPG is not secure if not done offline. So I would rather discourage naive people. Too many people died or ended up in prison because of this.
The only secure way (IMO) is to d/encrypt offline on a dedicated device, that never sees the internet, that even does not have an internet port. There is some gray zone regarding data transfer, but we don’t want to go into detail here.
