Transport Layer Security (TLS) is arguably the most important cryptographic protocol. Whether web, email, phone calls, chat, or VPN - there is hardly a type of communication which cannot be secured using TLS. Due to its importance, the protocol became target of many famous attacks, such as CRIME, DROWN, Logjam, or padding oracles. In 2018, a new standard version was released - TLS 1.3. This version was introduced to prevent all the protocol attacks and make the communication more performant.
In this hands-on tutorial, we gave a short introduction to TLS 1.3 and explained how you can analyze TLS 1.3 with Wireshark and TLS-Attacker.
