SSL/TLS Test

Check SSL/TLS security protocols, certificate validity, encryption strength, and secure connection status. Verify HTTPS implementation, check certificate details, and ensure secure communication. Essential for security auditing and web app security verification.

SSL/TLS encryption protects data in transit, with modern protocols like TLS 1.3 providing forward secrecy and protection against known vulnerabilities. Certificate validation ensures you're connecting to the legitimate website, not an imposter. This tester helps you verify your connection's security and identify potential vulnerabilities.

SSL/TLS Test

SSL/TLS Test Both

Check SSL/TLS security protocols and certificate information.

Click "Check SSL/TLS" to verify security protocols and certificate details.
Secure connections use TLS 1.2 or higher. Older protocols (SSL 3.0, TLS 1.0) are insecure.

Frequently asked questions about SSL/TLS Test

Use these answers to understand results, browser limitations, permissions, and sensible next troubleshooting steps.

How do I use the SSL/TLS Test?

Open the live ssl/tls test on this page and follow the prompts shown in the tester area. The tool runs directly in your browser, so you can check your device without installing additional desktop software or signing in.

What should I do if the ssl/tls test does not respond immediately?

Check browser permissions, confirm the device or browser feature is enabled, and reload the page if needed. Many browser-based testers depend on permission prompts, secure context support, or hardware access that must be approved before the test can run fully.

Why is this tester useful before troubleshooting or support calls?

Security audit - verify connection security. It can help you confirm whether the issue is caused by the hardware itself, a browser permission setting, or a system configuration problem before you spend more time debugging.
