Pi6eon 🐦

Like a carrier pigeon over IPv6.

Description

Pi6eon is a minimal, direct, stateless, and end-to-end encrypted CLI app that enables direct chatting between two IPv6/TCP endpoints.

Key exchange has been implemented using the x25519-dalek crate. The two parties generate a shared secret that is then used for symmetric message encryption using the aes-gcm crate. Please note that, although these two crates have been externally audited, there are no safety guarantees regarding their implementation in this project. ⚠️ USE AT YOUR OWN RISK ⚠️.

Finally, for communication to be possible, there needs to exist a network path free of any firewall or NAT restrictions between the two IPv6 addresses.
