TLS 1.3 Handshake: Taking a Closer Look - Medium

WebSep 21, 2024 · The difference between TLS 1.3 and TLS 1.2 is significant. The most important difference is that a TLS version 1.3 handshake takes less time than a TLS version 1.2 handshake. TLS 1.3 benefits include: Reduction of round-trip processing, resulting in a faster handshake. Improvement of latency times by reducing the number of round trips. A TLS handshake takes place whenever a user navigates to a website over HTTPS and the browser first begins to query the website's origin server. A TLS handshake also happens whenever any other communications use HTTPS, including API calls and DNS over HTTPSqueries.
