SYNRC 💬 CHAT

💬 CHAT: Instant Messenger respects IETF 3394 3565 5280 5480 5652 5755 8551 ITU ASN.1 X.509 CMS PKCS-10 PCKS-7 OCSP LDAP DNS X9-42 X9-62 X25519 X488 SECP384r1.

Features

• X.509 OpenSSL, LiberSSL for security;
• SYN/MAIL message delivery system;
• CA for X.509 client certificate enrollment;

CHAT protocol

The CHAT protocols communicates with actions/:client, events/:client, devices/:phone, contacts/:roster, private/:roster/:roster MQTT topics, sending through them Index, Typing, Search, Feature, Service, Desc, Presence, Friend, Tag, Link, Message, Member, Room, Contact, Star, RoomStar, Ack, Auth, Roster, Profile, History, push, io 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 N2O PROTO SPEC ASN.1/DER over TCP/MQTT/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.
