What is Secure Sockets Layer and what is it used for? SSL (Secure Sockets Layer) is a security protocol that provides a secure connection between a web 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 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 secure, you will see a security icon to the left of the URL. Clicking on this icon will provide additional information about the certificate, including its validity and the organization that issued it. You can also use online services to check SSL certificates, such as SSL Labs.
