Good afternoon everyone,
I have a quick question, must a Root CA operate an OCSP for intermediate certificates or is it only required for intermediate and end entity issuing CAs? Or in other words, must all CAB Forum compliant CAs operate an OCSP or only selected ones? It is not clear in the BRs which CAs must operate an OCSP.
4.9.10. On‐line Revocation Checking Requirements says
…the CA SHALL support an OCSP capability using the GET method for Certificates issued in accordance with these Requirements.
For the status of Subscriber Certificates…
For the status of Subordinate CA Certificates…”
In the BR Cert profiles, subordinate CA certs and end-entity certs MUST have an AIA (OCSP) extension, and they MAY have a CDP (CRL) extension. A subordinate CA having an OCSP in its AIA would denote that the issuing CA of that subordinate operates an OCSP.
We are looking at whether our Root CA must operate an OCSP for our intermediate CA certificates to be BR compliant.
