Secure Socket Layer (SSL) is a security protocol that creates an encrypted connection between a web server and a browser. It provides a secure connection and prevents third parties from accessing or modifying information transferred.
To get an SSL certificate, website owners must buy it from a Certificate Authority (CA). The CA will use the CSR or Certificate Signing Request to create the certificate.
The CSR is an encrypted text generated on the server where the certificate will be installed. It includes information such as the website’s domain name, contact details, and the public key to encrypt the data sent.
When the visitor’s browser tries to access the website, the web server will send a copy of the certificate for verification.
If the process is successful, an SSL-secured connection will be established. The website will use an URL that starts with HTTPS and, depending on the browser, a padlock icon will be displayed in the address bar.
