Server Random: 32-byte pseudorandom number used to generate the Master Secret.Server Version: The highest TLS protocol version supported by the server which is also supported by the client.The Server Hello contains the following information: The steps involved in the TLS handshake are shown below: The entire sequence which involves setting up the session identifier, TLS protocol version, negotiating the cipher suite, certificate authentication of the peers and cryptographic key exchange between peers is called a TLS Handshake. TLS protocol describes the steps to authenticate the peers and set up a secure connection with defined parameters. Handshake: To communicate over a secure channel, two peers must agree on the cryptographic keys and encryption algorithms for that session.Application Data: This protocol ensures that messages are fragmented, compressed, encrypted and transmitted in a secure manner.The change cipher spec message, transmitted by both the client and the server, defines the re-negotiated cipher spec and keys that will be used for all the messages exchanged henceforth. Change Cipher Spec: It defines changes in ciphering strategies.It is used to notify the peer of any error condition that has occurred. Alert: This sub-protocol defines the alert levels and provides a description of the alerts.
