TLS 1.3 is an overhaul of the TLS protocol with a simpler, less error-prone design that improves both efficiency and security. The new design reduces the number of round-trips required to establish a connection and removes legacy insecure options, making it easier to securely configure a server. It additionally encrypts more of the handshake and makes the resumption mode more resilient to key compromise.
