The ballot has PASSED.

Purpose of the Ballot

While RFC 5280, section 5.3.2 specifies that it is best practice to include the Invalidity Date CRL entry extension to denote when a certificate first became invalid, Certificate Consumer software commonly ignores this extension in favor of using the time encoded in the CRL entry revocationDate field for this purpose. This ballot clarifies that CAs shall use the revocationDate to denote when a certificate first became invalid even if that time precedes issuance of the latest CRL. Additionally, this ballot clarifies that if the CA is becomes aware of a more appropriate revocation date for a revoked Code Signing Certificate, then the CA may include this date in subsequently issued CRLs and OCSP responses pertaining to that revoked Code Signing Certificate.

Motion

This ballot updates the “Baseline Requirements for the Issuance and Management of Publicly‐Trusted Code Signing Certificates” version 2.5 according to the attached redline which includes:

  • Add the effective date of the CRL profile change in section 1.3.
  • Modification of the third paragraph of section 13.2.1.
  • Addition of two paragraphs after the third paragraph of section 13.2.1.
  • Add explanatory footnote to the bottom of the last page of section 13.2.1.

This ballot allows the option to use a European Unique Identifier (EUID) as a Registration Reference in the NTR Registration Scheme. The EUID uniquely identifies officially-registered organizations, Legal Entities, and branch offices within the European Union or the European Economic Area. The EUID is specified in chapter 9 of the Annex contained in the Implementing Regulation (EU) 2021/1042 which describes rules for the application of Directive (EU) 2017/1132 “relating to certain aspects of company law (codification)”. The ballot also includes several editorial corrections, (e.g., reordering of References and regrouping of information from Appendix A to Section 7.1.4.2.2 (d)). This ballot is proposed by Stephen Davidson (DigiCert) and endorsed by Adrian Mueller (SwissSign) and Adriano Santoni (Actalis).
