A Certificate Status Checker is a tool that verifies the validity and authenticity of SSL/TLS certificates used on websites. It ensures that the certificates are not expired, revoked, or issued by untrusted authorities. This helps organizations maintain secure communications and prevent potential security breaches.
Certificates play a crucial role in encrypting data between users and servers. If a certificate is compromised or invalid, attackers can intercept sensitive information. A Certificate Status Checker provides real-time validation to:
| Feature | Benefit |
|---|---|
| Expiry Detection | Prevents service disruptions by alerting before certificates expire. |
| Revocation Check | Identifies revoked certificates to avoid security risks. |
| Trust Verification | Ensures certificates are issued by trusted authorities. |
Most Certificate Status Checkers allow users to input a domain name or upload a certificate file. The tool then analyzes the certificate's details, including validity period, issuer, and revocation status. Regular checks help maintain a robust security posture and compliance with industry standards.
