A Detailed Look at RFC 8446 (a.k.a. TLS 1.3)
Aug 11, 2018Nick Sullivan
Summary
This post details the release and significance of TLS 1.3 (RFC 8446), highlighting its substantial security and performance improvements over previous TLS versions. It explains how TLS 1.3 addresses vulnerabilities inherent in TLS 1.2 (and earlier) by removing legacy features, fixing key exchange mechanisms (like RSA key exchange), and reducing handshake latency. This directly contributes to Cloudflare's ongoing efforts to provide robust website security by adopting and advocating for the latest, most secure encryption standards.
