In this release, I have implemented end-to-end encryption for the communication between hosts

In this second release, not everything is implemented, but I've added some core features:

• !sendfile
• almost completely rewritten the code in async with the Tokio runtime
• the chats can be password-protected
• implemented a commands side-box

This is the first demo release with only the basic feature, and not everything is implemented.
The implemented feature are:

• connections
• TUI
