Subject: [Servercert-wg] Voting Begins: Ballot SC23 V3: Precertificates

 

Purpose of Ballot:

 

This ballot intends to clarify requirements placed on Precertificates in BR section 4.9.10. 

 

During a lengthy discussion on the mozilla.dev.security.policy forum [1], it was discovered that BR section 4.9.10 combined with BR section 7.1.2.5 prevents a CA from responding “good” for a precertificate. This is a problem because there is no guarantee that a certificate corresponding to a Precertificate has not been issued, resulting in root store policies such as [2] that require CAs to treat the existence of a Precertificate as a presumption that a corresponding certificate has been issued and thus that a valid OCSP response is required.

 

This ballot intends to resolve the problem by clarifying in the BRs that a CA may provide revocation information for the serial number contained in a Precertificate.
