The CHAT protocols communicates with Inbox, Activity, Search, File, Presence, Friend, Message, Member, Conference, Person, Ack, Authority, Roster, History DER-serialized ASN.1-defined messages.

The CHAT protocol is implemented in the set of sub-protocol modules: FILE, HISTORY, LINK, MESSAGE, PRESENSE, PROFILE, PUSH, ROOM, ROSTER, SEARCH, AUTH. For full specification follow priv/design folder. The CHAT server implementation relies only on ISO/IETF connections such as DNSSEC, X.509 CSR, LDAP, QUIC, WebSocket.

• CHAT V2 ASN.1 SPEC DER over TCP/QUIC

CHAT is a simple instant messaging server based on ISO standards. It uses ASN.1 defined protocol and DER binary serialization from Erlang/OTP across applications: MAIL, LDAP, NS, CA. Secure by default. The CHAT application has Sign/Verify, Encrypt/Decrypt feature enabled for every single message passed by. The delivered messages are being deleted from instance after recipient acknowledgment. This is Keybase, OTR, PGP (you name it) replacement for secure X.509 ASN.1 defined communications.
