Security
The server generates self-signed certificate automatically, with the common name(CN) "localhost" by default. While the client always SKIP verification during a TLS handshake. Also, 0-rtt is enabled, at the risk of suffering from replay attack or MITM attack.
In general, you should NEVER rely on this program for security, though the traffic is still encrypted.
