Check the revocation status of an SSL certificate using OCSP. You can run the check by hostname (recommended) or by pasting a leaf certificate.

OCSP responders may return unknown depending on issuer policy or missing intermediate certificates.
If you paste a certificate, providing the issuer certificate improves reliability. Otherwise, the helper tries to fetch it from the certificate AIA extension.
