OCSP Watch

Methodology

OCSP Watch monitors Certificate Transparency for new certificates, and takes a random sampling of certificates from each issuer. If a certificate has OCSP responder information, OCSP Watch requests and evaluates the certificate's status using the Evaluate function from the open source software.sslmate.com/src/ocsputil Go package. If the evaluation is unsuccessful, OCSP Watch records it on this page and tries again later.
