OCSP/CRL Revocation Checker
Extract OCSP responder URLs and CRL distribution points from X.509 certificates. Check certificate revocation status
What OCSP/CRL Revocation Checker does
The OCSP/CRL Revocation Checker is a security utility that extracts Online Certificate Status Protocol responder URLs and Certificate Revocation List distribution points directly from X.509 certificates. Users can verify whether a digital certificate has been explicitly revoked before its natural expiration date, ensuring that SSL/TLS certificates remain trustworthy for network communications. The tool provides a critical layer of security validation for digital identities, helping security professionals and developers confirm certificate validity as part of maintaining secure connections.
How to use the Inventive HQ OCSP/CRL Revocation Checker
- 1
Paste or upload the X.509 certificate you wish to examine into the tool's input field
- 2
Submit the certificate to extract its embedded OCSP responder URLs and CRL distribution points
- 3
Review the extracted endpoints that indicate where revocation status can be queried
- 4
Use the provided endpoints to check the real-time revocation status through the respective services
- 5
Interpret the results to determine if the certificate remains valid or has been revoked
Best for
Security professionals, developers integrating authentication systems, and anyone handling digital certificates who need to verify certificate revocation status beyond simple expiration checks.
Limitations
- Results depend on the availability and responsiveness of external OCSP responders and CRL distribution points
- The tool extracts endpoints but does not guarantee real-time connectivity to all listed responders
- Revocation status may be influenced by network conditions or authority maintenance windows
OCSP/CRL Revocation Checker FAQ
- What is the difference between OCSP and CRL checks?
- OCSP provides real-time revocation status by querying a responder endpoint, while CRL checks consult a periodically published list of revoked certificates. This tool extracts both types of endpoints from your certificate for comprehensive validation.
- Can this tool check any SSL certificate I provide?
- Yes, the tool accepts X.509 certificates in various formats and extracts the embedded revocation checking endpoints, including OCSP responders and CRL distribution points.
- What if the OCSP responder or CRL is unavailable?
- If the extracted endpoints are unreachable, the tool will indicate that the revocation status cannot be determined at that moment. You may need to try again later or use alternative validation methods.
- Do I need technical expertise to use this tool?
- Basic familiarity with certificate concepts is helpful, but the tool is designed to extract and present the revocation endpoints clearly for users with varying levels of technical experience.
