 Free Online SSL/TLS Certificate Checker Tool 

 Instantly Validate Website Security & HTTPS Configuration 

Secure Sockets Layer (SSL), and its successor Transport Layer Security (TLS), are the technologies that power secure HTTPS connections online. Represented by the familiar padlock icon in your browser bar, an SSL/TLS certificate encrypts data sent between a website and its visitors, protecting sensitive information like login credentials and payment details. It also verifies the website's identity, assuring users they are connected to the legitimate server.

But how can you be sure a website's SSL certificate is properly configured, currently valid, and issued by a trusted authority? Our Online SSL Checker provides a quick and easy way to perform this vital verification.

Why Use an SSL Checker?

  • For Website Owners: Confirm your SSL certificate is correctly installed, active, not expired, and covers the intended domains after setup or renewal.
  • For Users: Verify the trustworthiness and security of a website before entering personal or financial information.
  • For Developers: Troubleshoot HTTPS connection errors and browser security warnings (like "NET::ERR_CERT_AUTHORITY_INVALID" or "Your connection is not private").
  • Inspect Certificate Details: View key information such as the Certificate Authority (CA) that issued the certificate, its validity period (issue and expiry dates), and the specific domain names (Common Name/Subject Alternative Names) it secures.

How to Use JadePlay's SSL Checker:

  1. Enter the domain name of the website you wish to check (e.g., example.com - no https:// needed).
  2. Click the "Check SSL Certificate" button.
  3. Our tool will connect to the website's server over the standard HTTPS port (443) and analyze the SSL/TLS certificate presented.

Understanding the Results: The checker will report the overall status (e.g., Valid, Expired, Mismatched Name) and display important details like the issuer, validity dates, algorithm used, and the domains secured by the certificate. This gives you a clear picture of the site's HTTPS configuration health.
