Ballot CSC-4 v1: Move deadline for transition to RSA-3072 and SHA-2 timestamp tokens

Purpose of the Ballot:

The current deadline for moving from RSA-2048 to RSA-3072 and from SHA-1 to SHA-2 for timestamp tokens falls on January 1, 2021, which is inconvenient due to code freezes due to the winter holidays. This ballot delays the deadline to June 1, 2021 for RSA-3072 and April 30, 2022 for SHA-2 timestamp tokens.

The following motion has been proposed by Tim Hollebeek of DigiCert, and endorsed by Ian McMillan of Microsoft and Hugh Mercer of GlobalSign.

Motion begins

This ballot modifies the “Baseline Requirements for the Issuance and Management of Publicly‐Trusted Code Signing Certificates“ version 2.0 according to the attached redline.

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)
