Session
A packet-level tour of the TLS family. What stays visible when everything's encrypted? TLS is everywhere, and most people assume that means "encrypted, end of story." But TLS is a family of protocols, and each member leaves a different footprint on the wire. This talk is a tour of that family through Wireshark, built around a single idea: encryption hides content, not behaviour.
