The client sends a client hello message to the server. Step #1: Client Hello The first step to start a TSL handshake with ‘ Client Hello’ The TLS handshake will kick in with client hello.

Once the TCP three-way handshake is done. The source and destination IP address used in this demo TLS v1.2 Protocol Handshake: 199.38.167.35 is the destination Pluralsight. TCP three-way handshakeġ92.168.0.114 is the client machine. At last, the client sends the acknowledgment to the server. Second, the server sends SYN + ACK in response to the client. First, the client sends the SYN packet to the server. To tell in short, a TCP handshake is a three-step process. TCP handshake process is a separate topic, so we are not covering that in this article. In HTTP, the TLS handshake will happen after the completion of a successful TCP handshake.

Step #5: Change Cipher Spec And Finished.

Step #4: Client Encrypted Key, Change Cipher Spec, and Finished.

Step #3: Certificate, Server Encryption Key, and Server Hello Done.
