OCSP status checker

Paste a certificate and read the OCSP responder URLs and Must-Staple flag it carries, with a ready openssl command for the live check.

This tool is in beta

Still being tested. If a result looks wrong, tell us.

Report a problem

Paste a certificate to read its revocation material.

A browser tab cannot open a raw TLS handshake to an arbitrary host, and OCSP responders do not send CORS headers, so no live probe happens here. That is why this page never states a revocation verdict and always reports stapling as unknown: both facts live on the server, not in the certificate. The openssl command in the result is the next step on a machine with network access, and it verifies the response signature, which a browser page cannot do either.

Certificate

Paste the leaf certificate. Up to 200,000 characters.

Reading happens in this tab. The certificate is never uploaded, and no OCSP responder or CRL distribution point is contacted.
