Introducing TLS 1.3
Sep 20, 2016Nick Sullivan
Summary
This post introduces TLS 1.3 as a significant upgrade to encrypted internet traffic, available to all Cloudflare customers. It highlights TLS 1.3's key benefits: enhanced security through the removal of outdated and vulnerable cryptographic features (like RSA key transport, CBC mode ciphers, RC4, SHA-1, and arbitrary Diffie-Hellman groups) and improved speed by reducing the handshake process from two round-trips to one, with a future plan for zero round-trip mode (0-RTT). This directly contributes to the ongoing effort to secure and optimize web traffic.
