– Step 1: Get the server certificate. First, make a request to get the server certificate.
– Step 2: Get the intermediate certificate. Normally, a CA does not sign a certificate directly.
– Step 3: Get the OCSP responder for server certificate.
– Step 4: Make the OCSP request.
The Online Certificate Status Protocol (OCSP) is an Internet protocol used for obtaining the revocation status of an X. 509 digital certificate. It is described in RFC 6960 and is on the Internet standards track.
D’autre part, What is OCSP and CRL?
OCSP (RFC 2560) is a standard protocol that consists of an OCSP client and an OCSP responder. CRL is the traditional method of checking certificate validity. A CRL provides a list of certificate serial numbers that have been revoked or are no longer valid.

What is the difference between CRL and OCSP?
OCSP (RFC 2560) is a standard protocol that consists of an OCSP client and an OCSP responder. This protocol determines revocation status of a given digital public-key certificate without having to download the entire CRL. A CRL provides a list of certificate serial numbers that have been revoked or are no longer valid.
How does CRL checking work?
– A GET request is made to an HTTPS-enabled page.
– The certificate authority receives that request and returns a list of all revoked certificates.
– The browser then parses the CRL to ensure that the certificate of the requested site isn’t contained within it.
