An overview of TLS 1.3 and Q&A
- In 1.3, Finish message signs the entire transcript
- Client guesses the list of supporter ciphers and sends own seed with initial flight
- PSK can be an ID or an encrypted payload; an opaque blob
- Replay attacks: server can ignore the data by not acking in Finish and forcing the client to resubmit
- There is no forward secrecy for 0-RTT handshakes due to preshare
- Server echoes "downgrade" in its random data to identify a 1.3 capable client
