Goal: Create a simple and secure P2P sync prototype.

• Using libsodium for creating key-pairs for identity and encryption.
• Using simple-peer for WebRTC.
• Using signalhub as a public discovery channel for WebRTC.
  • Consider using mDNS, BLE, WiFi Direct, and DHT.
  • Consider using @hyperswarm/discovery.
  • Consider using libp2p.

WebRTC says it can set up a secure channel, but is vulnerable to MITM if the discovery channel is insecure. I'm assuming that encrypting the signaling packets should solve that issue.

1. Run node app.js in the build directory to open a peer connection.
2. Open another peer connection with node app.js on another process or machine.
3. Exchange secure hashes as prompted to instantiate a connection and begin talking.
