About SSL Certificates

An SSL (Secure Sockets Layer) certificate encrypts data between a user's browser and a website's server, ensuring that information like passwords, credit cards, and personal data cannot be intercepted. Websites with SSL certificates show a padlock icon in the browser address bar and use HTTPS.

SSL certificates expire — usually after 90 days (Let's Encrypt) or 1–2 years (paid CAs). An expired SSL certificate causes browser warnings that drive users away. Use this tool to regularly monitor your SSL certificate expiry and renew before it expires.
