Ballot Contents
This is v2 of this ballot; you can see the discussion thread for v1 here: https://lists.cabforum.org/pipermail/servercert-wg/2024-August/004798.html
This ballot attempts to address three concerns:
- The confusion around “reserved” serials, which do not actually exist because all Precertificate serials are assumed to also exist in corresponding Certificates and are therefore actually “assigned”;
- Confusion around whether, and how quickly, OCSP responders must begin providing authoritative responses for Certificates and Precertificates; and
- Confusion around whether and how the OCSP requirements apply to Certificates which do not contain an AIA OCSP URL, but for which the CA’s OCSP responder is still willing to provide responses.
It addresses these concerns by:
- Stating that OCSP responses must be available within 15 minutes of signing a certificate containing an AIA OCSP URL;
- Removing the concept of a “reserved” serial entirely;
- Moving all OCSP requirements into Section 4.9.9, leaving Section 4.9.10 (which RFC 3647 says is meant to place requirements on relying parties, not on CAs) empty; and
- Organizing the requirements in Section 4.9.9 into three clusters:
- Definitions of “validity interval”, “assigned”, and “unassigned”;
- Requirements on OCSP Responders, which apply only to responses from AIA OCSP URLs found in issued certs; and
- Requirements on OCSP Responses, which apply to all responses regardless of whether the certificate in question has an AIA OCSP URL.
