Review of Agenda: There were no additions.

Approval of Minutes from Last Call of January 5, 2023: minutes were approved.

Next minute-taker – Bruce Morton (February 2, 2023)

Forum Infrastructure Subcommittee update – Corey Bonnell said two main topics were discussed-wiki migration beginning in February and replacement of some GitHub tooling for generating PDF and Word documents that is being deprecated. Ben also mentioned that he had added minutes pages for working groups to the website.

Code Signing Certificate Working Group update – Janet Hines said the group worked on alternate language for the ballot on malware revocations that they would be discussing next week. Also, in section 7.1.4.2.3 there are references to the SSL/TLS Baseline Requirements that need to be removed.

S/MIME Certificate Working Group update – Martijn Katerbarg said that they were working to incorporate some requirements (not before the effective date, but sometime early in 2024). Mozilla’s potential adoption of the S/MIME BRs was also discussed.

Network Security Working Group update – Ben Wilson said that the cloud computing sub-group was reviewing the Cloud Security Alliance’s security controls matrix, and on the last NetSec WG call they developed some narrative guidance language to proceed each of the four major sections of the Network and Certificate System Security Requirements.

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)
