In the SSL handshake both the client and server generate their respective random numbers.

So, when you connect to a server, how do the endpoints decide which protocol version and encryption algorithms to use? When the client establishes a secure connection, a SSL/TLS handshake is performed between the client and server

TLS is based on SSL, so you can think of TLS as the newer flavor of SSL.

TLS is a proposed Internet Engineering Task Force standard, first defined in 1999, and the current version is TLS 1.3 defined in RFC 8446 (August 2018)

The TLS protocol comprises two layers: the TLS record and the TLS handshake protocols.

Browser will then initiate the TLS handshake request The new location, say, will be specified with the port number 443. If the server supports TLS, then it will respond to the browser by saying a protocol upgrade request. Once the IP is resolved, the browser will request the page via http. The SSL/TLS handshake involves a series of steps through which both the parties - client and server, validate each other and start communicating through the secure SSL/TLS tunnel As it goes with all handshakes, the SSL/TLS Handshake is where it all starts.

The SSL/TLS handshake process simplified like never before.

Like for a TCP connection, a TLS connection starts with a handshake between the client and the server: The client sends a Client Hello message, including a list of 32-byte list of random data and the list of its supported cipher suites

This header may be followed by another TLS header, such as a TLS Handshake header.

This section provides a summary of the steps that enable the SSL or TLS client and server to communicate with each other: Agree on the version of the protocol to use. The Transport Layer Security (TLS) Handshake Protocol is responsible for the authentication and key exchange necessary to establish or resume secure sessions The SSL or TLS handshake enables the SSL or TLS client and server to establish the secret keys with which they communicate. Some of these are easy to fix, some of them are a little more involved and some might not be worth fixing at all. The majority of the time SSL/TLS handshake failures are the result of server-side issues. What Is an SSL/ TLS Handshake? Obligatory SSL/TLS Handshake Graphic Let's Clear Up Some Confusion, If We Can: Asymmetric vs symmetric encryptio SSL/TLS Handshake Failed: Server-Side Errors. This article will show how every SSL/TLS connection begins with a handshake that determines just how two parties to an internet connection shall encrypt their communications.
