2026-04-16 Minutes of the Code Signing Certificate Working Group

Code Signing Working Group – Meeting Minutes

Date: 16 April 2026
Chair: Martijn Katerbarg (Sectigo)
Meeting Type: Teleconference


1. Antitrust Reminder (Note Well)

The Note Well was read.


2. Review of Agenda

The agenda was circulated earlier on the day of the meeting.

  • The Chair noted that the Interested Party application originally on the agenda had already been approved and would therefore be skipped.
  • Dean Coclin raised a second pending Interested Party application from Nova Vanguard (China), submitted on 1 April.
  • Dean noted that he had questions regarding whether the application had been signed by an appropriate organizational representative and had not yet received clarification.
  • It was agreed that Dean would follow up directly with the applicant before the application proceeds.

No other agenda changes were proposed.


3. Interested Party Applications

Nova Vanguard

The working group discussed the pending Interested Party application from Nova Vanguard.

  • Questions remain regarding whether the individual who signed the application is authorized to do so on behalf of the organization.
  • Dean Coclin will contact the applicant to clarify the appropriate signatory before the application is considered further.

4. Discussion Topics

4.1 SCWG Alignment Ballot

The Chair summarized the email sent to the public mailing list describing the proposed alignment changes with the Server Certificate Working Group.

Discussion included:

  • The Chair’s assessment was that the proposed changes are primarily clarifications rather than substantive compliance changes.
  • Corey Bonnell agreed with this assessment, noting that the only significant new requirement appears to be the introduction of a 15-minute deadline.
  • The Chair observed that this could even be interpreted as a relaxation of the existing requirements.
  • Microsoft concerns remain unresolved due to the absence of Microsoft representatives from the meeting.

4.2 Reserved Policy OID Mandatory in Code Signing Certificates

Adriano Santoni reported that there were no updates beyond the discussion already held on the mailing list.

The Chair confirmed that the proposal was still awaiting a second endorser.

Corey Bonnell volunteered to endorse the ballot proposal.


4.3 Update on Pending Ballot Proposals from Microsoft

Skipped. No Microsoft representatives were present.


5. Any Other Business

  • The Chair noted that several sets of meeting minutes had recently been circulated to address the backlog.
  • Approval of those minutes will be deferred until the next meeting to allow sufficient review time.
  • Dean Coclin noted that he had submitted comments regarding the attendee list for the Face-to-Face meeting minutes.
  • The Chair confirmed those comments would be incorporated.

The meeting schedule was also discussed.

  • Corey Bonnell asked whether the working group would continue meeting every two weeks.
  • The Chair confirmed that the group would resume the biweekly meeting cadence, following Microsoft’s earlier request, with the schedule to be reviewed again if necessary.

6. Adjourn

The meeting was adjourned.


7. Next Meeting

Date: Two weeks from 16 April 2026.

The ballot further requires that by September 15, 2027, CAs SHALL NOT issue Subscriber certificates from any Sub-CA whose RSA key modulus is less than 3072 bits, effectively sunsetting issuance from legacy 2048-bit Sub-CAs.
