This article explains SSL certificates and how to check their installation. Let's explore the essentials of SSL and reliable SSL checkers.

What is SSL?

SSL, or Secure Sockets Layer, is a protocol establishing secure, encrypted connections between computers. While largely superseded by TLS (Transport Layer Security) since 1999, the term "SSL" is still commonly used to refer to both technologies (often as SSL/TLS).

What is an SSL Certificate?

An SSL certificate (also called a TLS or SSL/TLS certificate) is a digital document linking a website's identity to a cryptographic key pair (public and private keys). The public key allows browsers to initiate encrypted communication with the web server using TLS and HTTPS. The private key, kept secure on the server, digitally signs website content (including images and JavaScript). The certificate also contains identifying website information, including the domain name and owner details. If signed by a trusted Certificate Authority (like SSL.com), the digitally signed server content is deemed authentic by user browsers and operating systems. SSL certificates are always X.509 certificates.
