This article will guide you to enable TLS 1.3 on your browser. This feature gives an extra speed boost while browsing, when user return to a TLS secured website which they previously visited, it will load very faster if you enabled TLS 1.3 on your Browser. TLS 1.3 introduced a new feature call Zero round trip time resumption or 0-RTT. It completes the handshake in just one trip so it cuts down on encryption Latency. TLS 1.3 offers faster encryption compared to TLS 1.2, and TLS 1.3 handshake is faster compared to TLS 1.2. TLS 1.3 is mainly focused to improve performance, Privacy, and security. To overcome these issues IETF officially released TLS 1.3 in 2018. Then TLS 1.1 was added with little extra features, The TLS 1.2 was published as RFC 5246 in 2008, then over the years monitoring researchers have discovered a slew of vulnerabilities. The protocol was renamed TLS to avoid legal issues with Netscape, which developed the SSL protocol as a key feature part of its original Web browser. The IETF officially took over the SSL protocol to standardize it with an open process and released version 3.1 of SSL in 1999 as TLS 1.0. These are the basic working principle of TLS. Also for each message ends client and server gets a certificate of authentication and finishes the handshake process, This session ID will be saved for future use so that This TLS session can be resumed in the future. This multi-step process is a little complex that the record protocol, in TLS, a server provides an identity to the client by the use of public and private key pairs, Then the session key has been generated and shared between client and server, then the main part is establishing a secure session by using TLS, In this client and server exchanges the simple hello messages with encryption keys.
When establishing a secure session, the Handshake Protocol manages the following: Transport Handshake Protocol is a multi-step process, Handshake Protocol is responsible for the authentication and key exchange necessary to establish or resume secure sessions. When the Record Protocol is complete, the outgoing encrypted data is passed down to the Transmission Control Protocol (TCP) layer for transport.
