TLS 1.3

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.

Comments

TLS 1.3 was a multi-year project spanning contributions across the industry, academic research groups, and other participants in the standards process. We previously experimented with earlier drafts of the standard and, with the final standard done, are now excited to ship to it in Chrome.
