Added encryption but not in the usual way. More like SSH than TLS. The eventual intention is to use a combination of DNSSEC and TXT records to prove that a server belongs to somebody. The server's public key is in the TXT record! There is prior art of a similar approach.
So when you establish a session, we use the libsodium key exchange protocol to set up a secure session. Then all future messages are encrypted between client and server safely!
Well.. I hope. I am not a security person. But they say if you use libsodium you probably can't go wrong?
Ha!
