What is an SSL Certificate?

An SSL (Secure Sockets Layer) certificate is a digital certificate that secures the connection between your website and its visitors. It encrypts sensitive data—such as passwords, credit card numbers, and personal information—ensuring safe and private communication over the internet.

Why is SSL Important?

  • Data Encryption: Protects all information exchanged with your website from eavesdroppers.
  • Authentication: Confirms your website’s identity, assuring users they are on the legitimate site.
  • Trust & SEO: Displays a secure padlock in browsers, building user trust and improving your search engine ranking.

About the SSL Checker Tool

Use our SSL Checker to instantly analyze your website’s SSL certificate. Enter your domain to view certificate validity, expiration date, HSTS status, and more. This tool is ideal for troubleshooting SSL issues or confirming your site’s security.

Key Features

  • Certificate Status: Instantly check if your SSL certificate is active and valid.
  • Expiration Monitoring: See the certificate’s expiration date and days remaining.
  • HSTS & CAA Records: Verify HTTP Strict Transport Security and CAA DNS records.
  • Certificate Chain Analysis: Inspect the full certificate chain for browser compatibility.
