How trojan works?
When a trojan client connects to a server, it first performs a real TLS handshake.
If the handshake succeeds, all subsequent traffic will be protected by TLS; otherwise, the server will close the connection immediately as any HTTPS server would.
(Trojan now also supports nginx-like response to plain HTTP requests.)
