TLS 1.3 Handshake - many CHANGES from prior versions! 

The TLS 1.3 Handshake changes significantly from the TLS 1.2 (and prior) handshake. In this video we discuss 4 major changes to the TLS handshake with the latest version:
- TLS 1.3 Handshake is shorter, only one round trip (1RTT)
- TLS 1.3 Handshake is mostly encrypted (everything except the Client Hello and the Server Hello)
- TLS 1.3 Handshake encrypts the Client Certificate (as well as the Server Certificate)
- TLS 1.3 Handshake generates many more session keys
