Minutes

Antitrust Statement: Read by Dean Coclin

Minute Taker: Martijn Katerbarg

Minutes of the June F2F meeting were approved

Signing Service discussion (continued)

With Bruce being absent from this meeting and having worked a great deal on this item, the group decided to hold off on discussing this item.

Timestamping (continued)

Ian has checked with Karina. They are working on doing a broad update of the root policy requirements and will be bundling this in.

Corey mentioned that we should be doing a cleanup ballot and then work on a ballot for a number of timestamp items

Proposal to revocation based on malware

Martijn sent out an email on Monday with a proposal to change the language related to malware revocation. As of yesterday, there is also a draft pull request available on Github (https://github.com/cabforum/code-signing/pull/10)

There were no direct comments to the proposal

Other Business

Dean brought up having issues with write access on the code-signing Github repository. It was confirmed the pull-request was merged, meaning Github is up to date after CSC-14 has passed.

Corey suggested the Infrastructure subcommittee might need to address the overall Github access setup

The next meeting is set for July 14th.

S/MIME Requirements
v1.0.15 - Ballot SMC017v2 - Jul 30, 2026

This ballot increases the minimum RSA key size for Root and Subordinate CA certificates in the S/MIME BRs from 2048 to 4096 bits for keys created after September 15, 2026, while retaining the 2048-bit minimum for Subscriber certificates. 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. The ballot also includes minor typographic corrections. This ballot is proposed by Martijn Katerbarg (Sectigo) and endorsed by Ben Wilson (Mozilla) and Stephen Davidson (DigiCert)
