SSL and its descendent, Transport Layer Security, are protocols that encrypt internet traffic. The next major version of the protocol, TLS 1.3, will soon be finalized. The two form a continuously updated series of protocols, and are often lumped together as SSL/TLS. The handshake process is quite complex, and there are a number of variations allowed by the protocol. There are several techniques for doing this, but the most important thing you need to know about them is that they contain the server’s public key.”]
