Ballot SC052v2: Specify CRL Validity Intervals in Seconds

Ballot SC-52 version 2: Specify CRL Validity Intervals in Seconds

This ballot expired before entering the voting period.

Purpose of Ballot: Similar to Ballot SC-31 which modified the specification of

OCSP validity periods to be in seconds, this ballot modifies the specification

of CRL validity periods to be in seconds to avoid confusion about exactly which

periods are valid and which are not. The ballot also specifies that other time

periods should be handled the same way, which has broader impacts throughout

the document.

These changes should not be interpreted as implying that missing a deadline by

a few seconds is any more or less important than it previously was. The

changes are merely intended to provide additional clarity and precision about

exactly where the deadlines are.

The following motion has been proposed by Tim Hollebeek of DigiCert and endorsed

by Trevoli Ponds-White of Amazon and Kati Davids of GoDaddy.

-MOTION BEGINS This ballot modifies the “Baseline Requirements for the Issuance and Management

of Publicly-Trusted Certificates” (“Baseline Requirements”), based on Version 1.8.0:

MODIFY the Baseline Requirements as specified in the following 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)
