SSL Checker

Check SSL certificate information for any website

What is SSL?

SSL (Secure Sockets Layer) encrypts data between your browser and websites. It protects sensitive information like passwords and credit card numbers.

Why check SSL?

  • • Verify certificate validity
  • • Check expiration date
  • • Identify certificate issuer
  • • Ensure secure connection

Frequently Asked Questions

What happens when SSL expires?

Browsers will show security warnings to visitors, potentially driving them away and hurting your SEO rankings.

How often should I check my SSL?

Check monthly or set up automated monitoring. Most certificates expire annually and need renewal.

What is the difference between SSL and TLS?

TLS is the successor to SSL. While we commonly say "SSL", modern websites actually use TLS for encryption.

💡 Pro Tips

  • • Renew SSL certificates at least 30 days before expiration
  • • Use free SSL from Let's Encrypt for personal websites
  • • Consider EV (Extended Validation) SSL for e-commerce sites
