Frequently Asked Questions
What is an SSL certificate?
An SSL/TLS certificate authenticates a website's identity and enables an encrypted connection between a web server and a browser.
How do I know if my SSL certificate is about to expire?
Enter your domain in our SSL checker. It shows the exact expiry date and days remaining, with warnings for certificates expiring within 30 days.
What's the difference between SSL and TLS?
TLS (Transport Layer Security) is the successor to SSL (Secure Sockets Layer). Modern connections use TLS 1.2 or 1.3, though they're commonly still called "SSL."
