Description

TLS used to expose data like Server Name Indication during the handshake. Encrypted Client Hello (ECH) fixes that by encrypting handshake info, defeating SNI-based blocking. This episode covers how ECH works, its adoption push, and how censors might react. It also explores the privacy vs. visibility debate between users and network operators focused on security.
