Like a carrier pigeon over IPv6.
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.
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.
