TLS 1.3 Handshake - Major Changes from Prior Versions

Explore the significant changes in the TLS 1.3 handshake compared to previous versions in this 18-minute video. Dive into four major modifications: the shorter one round trip (1RTT) handshake, increased encryption of handshake components, encryption of client certificates in mutual TLS, and the generation of additional session keys. Learn about zero round trip (0RTT) handshakes, Encrypted Server Name Indication (ESNI), and Encrypted Client Hello (ECH). Gain insights into the enhanced security features of TLS 1.3 and understand how these changes impact network communications and cybersecurity practices.
