What is SSL certificate and what is it used for? SSL (Secure Sockets Layer) is a security standard that provides a secure connection between a server and the user's browser. It protects the transmitted information, preventing the interception of data such as logins and credit card numbers. SSL helps increase user trust, as websites with SSL certificates typically have addresses starting with " HTTPS ".
How can I check if an SSL certificate is installed on a website? To check for the presence of an SSL certificate on a website, you can simply look at the browser's address bar. If the site is with a secure connection, you will see a lock icon to the left of the URL. Clicking on this icon will provide additional information about the certificate, including its expiration date and the organization that issued it. You can also use online services to check SSL certificates, such as SSL Labs.
