UIT Chat is a WinForms desktop chat application backed by a central TCP/TLS server. A user connects with the server address and certificate fingerprint, registers or logs in, then uses the chat interface for messaging and related social features; the server persists shared state and attachments. The README documents authentication, presence, friends, groups, history, search, file sharing, and access control. Detailed UI request handlers and some server internals were not sampled, so those relationships are shown only where source or documentation supports them.
