SSL Checker

Check certificate validity and TLS configuration.

Sensitive processing stays in your browser whenever possible.

Details

Weak TLS configuration, expired certificates, or incomplete chains cause user warnings and in worse cases enable downgrade. Regular checks of public domains are essential.

A future version will show certificate validity, expiry dates, and signs of insecure configuration so operations can act before an incident.

Tips

Disable legacy protocols such as TLS 1.0/1.1.
Automate certificate-expiry monitoring; most outages come from forgotten renewals.
Use valid, trusted certificates for internal services too.
