Welcome to Chast! A modern, peer-to-peer chat application built with Rust that lets you create secure, direct connections with friends without needing any central servers.

Make sure you have:

• Rust - The latest stable version (get it here)
• An internet connection - For initial peer discovery (then it's all direct!)
• A friend to chat with - Because chatting alone isn't as fun 😄

git clone https://github.com/temidaradev/p2p-vpn-rust.git
cd p2p-vpn-rust

cargo build --release

Grab a coffee - this might take a few minutes the first time as Rust downloads and compiles all dependencies...

cargo run --bin p2p-chat

For a more traditional chat experience with message tracking and room management, you can run the server component. This provides additional features beyond pure peer-to-peer communication :3

cargo run --bin server

You can also install pre-built executables for both the chat GUI and server from the releases page.

That's it!

1. Run the application
2. Click "Create Room"
3. Enter your username
4. Click "Create"
5. Copy the ticket this is your room's "ticket"
6. Share this ticket with friends you want to chat with!

1. Get a ticket from a friend
2. Run the application
3. Click "Join Room"
4. Enter your username
5. Paste the ticket
6. Click "Join"
7. Start chatting!

If you want to enter the server im hosting on my server, you can join by pasting this room id into related section:

Curious about the magic? Here's the simplified version:

1. Room Creation: When you create a room, your computer becomes a "host" with a unique network address
2. Ticket Generation: The app creates a special "ticket" containing your network address and a secret room ID
3. Direct Connection: When someone uses your ticket, their app connects directly to yours
4. Peer-to-Peer: From then on, messages flow directly between devices using Iroh

No servers, no data collection, no corporate oversight

But using the server option breaks this...

This is a Rust workspace with several components:

• p2p-chat/ - The main GUI application (what you actually run)
• server/ - Optional server to break the rules of p2p :3
• messaging/ - Message format and serialization logic
• ticket/ - Room "ticket" encoding/decoding
• target/ - Compiled binaries (created when you build)
