P2PThing

A cross platform peer-to-peer chat and voip application written in rust

Usage

• Download a built binary
• Or build it yourself:
  • Run the rendezvous server: cargo run --release s
  • Run the client(s): cargo run --release --features client,audio c

By default the client will try to connect to 127.0.0.1:42069. However if you want to specify the IP, then run the client like this: cargo run --release --features client,audio c 192.168.10.30:42069, where 192.168.10.30 is the ip and 42069 is the port obviously.

Implemented Features

• Multi peer chat
• UDP Punchthrough
• Encryption on all communications
  • Asymmetric RSA encryption while in handshaking phase
  • Symmetric AES-256 encryption once connected
• Audio support
  • Opus encoded
  • Variable bitrate (Down to 2 kbit/s)
  • Input resampling
  • Output resampling
  • Togglable noise suppression
• TUI (Terminal User Interface)
• Cross platfrom support
  • Windows - Full support
  • Linux - I'll do my best to support linux
  • Mac - No idea, don't have one, altough probably could work

Features that could be implemented

• Screen sharing
  • Probably with ffmpeg
    • DXGI on windows
  • Capturing and streaming application audio
    • Either with a loopback device
    • Or by directly hooking into an application, like how discord does it
• File sharing
