Demystifying the TLS Handshake: What it is and how it works

WebNov 4, 2024 · This is part of a process known as the TLS handshake — of which there are three versions (TLS 1.0, TLS 1.2 and TLS 1.3). After that, we use symmetric encryption for the actual bulk of the data encryption that takes place during your session. In general, the TLS handshake: Enables our web server to authenticate itself to your browser (web client), WebSep 8, 2024 · Symmetric secrets. Asymmetric cryptography also requires more computational resources than symmetric cryptography. Thus when a TLS handshake begins with an asymmetric exchange, the client and server will use this initial communication to establish a shared secret, sometimes called a session key. WebSSL/TLS uses both asymmetric and symmetric encryption to protect the confidentiality and integrity of data-in-transit. Asymmetric encryption is used to establish a secure session between a client and a server, and symmetric encryption is used to exchange data within the secured session.

WebJul 19, 2024 · The goal of the TLS handshake is for the client and the server to agree on a shared symmetric encryption key in a secure fashion. To do so, they use asymmetric encryption, which allows encrypted messages to be sent using only a public key. The details of the TLS handshake depend on the asymmetric encryption algorithm used.
