[44net] AX.25 with digital signatures and binary compression

Hi all, I just saw this project on the Github, and it looks related and might be very interesting to you. Check it out! https://github.com/brannondorsey/chattervox An AX.25 packet radio chat protocol with support for digital signatures and binary compression. Like IRC over radio waves. Chattervox implements a minimal packet radio protocol on top of AX.25 that can be used with a terminal node controller (TNC) like Direwolf to transmit and receive digitally signed messages using audio frequency shift keying modulation (AFSK). In the United States, it's illegal to broadcast encrypted messages on amateur radio frequencies. Chattervox respects this law, while using elliptic curve cryptography and digital signatures to protect against message spoofing. -- Regards, Quan Zhou
