SSL Handshake Introduction

Before we delve deep into what causes a TLS or SSL handshake failure, it is beneficial to understand what TLS/SSL handshake is. Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are protocols utilized to authorize the transfer of data between servers and external systems like browsers.

SSL certificates are required to safeguard your website using HTTPS. We won’t discuss in deep about the difference between TLS vs SSL. The terms are often utilized conversely, therefore for your ease, we will utilize the term ‘SSL’ to refer to both.

With that being said, an SSL handshake is the initial step in the process of establishing an HTTPS connection. To validate and form the connection, the users’s browser and the site’s server must surpass few checkpoints (handshake), that establish the HTTPS connection parameters.
