Email from Bruce Morton (Entrust) 10/31/24

  • aligning the code signing BRs with SCWG BRs
  • Cory evaluated the ballot concerns
  • Ballot SC-73 - has some value with CSCWG
  • Ballot SC-75 - Pre-Sign linting - there is no linting created for CS at this time.
  • Ballot SC-76v2 -OCSP requirements - Microsoft removed their requirements. Martijn feels like we could follow the ballot; Corey agrees that the 15-minute rule has some value to Code Signing. There’s lots of pre-cert language in the ballot that does not relate to Code Signing.
  • Ballot SC-77 - Update Web Trust Audit name in Section 8.4 and references - already addressed
  • Ballot SC-78 - Subject organizationName - Martijn is checking to see if there are CS issues
  • Ballot SC 79v2 - allow more than one certificate policy - not relevant in CS environment.
  • Martijn mentioned a desired logging ballot; and will update the list with it, later.

Other business

  • New Chair starting 12/1/24 - Martijn and new Vice Chair Thomas
  • No meeting on 11/28 for Thanksgiving – Martijn will lead the meeting on 12/12; need to set new hosts for the WebEx meeting.
  • Dean gave a great farewell speech, and we all thanked him for his great service to the CSCWG

S/MIME Requirements
v1.0.12 - Ballot SMC014 - Oct 13, 2025

This ballot introduces requirements that a Certificate Issuer MUST deploy DNSSEC validation back to the IANA DNSSEC root trust anchor on all DNS queries associated with CAA record lookups performed by the Primary Network Perspective, effective March 15, 2026. The ballot is intended to maintain consistency in the S/MIME Baseline Requirements with the requirements of Ballot SC-085 which implemented identical requirements in the TLS Baseline Requirements. Note: SC-085 also introduced requirements in TLS Baseline Requirements for the use of DNSSEC in domain control validation. These requirements are automatically adopted in the S/MIME BR by the email domain control methods that include a normative reference to section 3.2.2.4 of the TLS Baseline Requirements. The draft also includes minor corrections to web links in the text. This ballot is proposed by Stephen Davidson (DigiCert) and endorsed by Client Wilson (Apple) and Ashish Dhiman (GlobalSign).
