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
v1.0.14 - Ballot SMC016 - May 5, 2026

This ballot maintains consistency between the S/MIME Baseline Requirements and the TLS Baseline Requirements with changes introduced by Ballots SC096 and SC097. Specifically, this ballot: Creates a carve-out of the logging requirements for DNSSEC specifically, stating these are not in scope. For audit purposes, change management logging is able to confirm if the appropriate controls are in effect or not. Sunsets all remaining use of SHA-1 signatures in Certificates and CRLs. It is noted that most uses of SHA-1 signatures are already deprecated by SC097. With this ballot, all unexpired Subordinate CA Certificates issuing S/MIME containing the SHA-1 signature algorithm must be revoked. This proposal does not prohibit the use of SHA-1 to generate issuerKeyHash or issuerNameHash values as currently required by RFC 5019. Includes minor formatting corrections.

Network and Certificate System Security Requirements
Version 2.0.5 (Ballot NS-008) - Jul 9, 2025
