Baseline Requirements 1.1.7 and 1.1.8 Re-Posted

A couple of formatting errors were identified in the Baseline Requirements, and versions 1.1.7 and 1.1.8 have been replaced with corrected versions. Appendix A in versions prior to version 1.1.7 had parts of RSA public key exponent requirements as superscript. It should have read: “The CA SHALL confirm that the value of the public exponent is an odd number equal to 3 or more. Additionally, the public exponent SHOULD be in the range between 216+1 and 2256-1.” That is corrected in version 1.1.7. Also, versions 1.1.7 and 1.1.8 had combined the text at the end of section 11.1.4 as part of the title of section 11.2. That has been corrected in those two versions.

S/MIME Requirements
v1.0.14 - Ballot SMC016 - May 5, 2026

This ballot maintains consistency between the S/MIME Baseline Requirements and the TLS Baseline Requirements with changes introduced by Ballots SC096 and SC097. Specifically, this ballot: Creates a carve-out of the logging requirements for DNSSEC specifically, stating these are not in scope. For audit purposes, change management logging is able to confirm if the appropriate controls are in effect or not. Sunsets all remaining use of SHA-1 signatures in Certificates and CRLs. It is noted that most uses of SHA-1 signatures are already deprecated by SC097. With this ballot, all unexpired Subordinate CA Certificates issuing S/MIME containing the SHA-1 signature algorithm must be revoked. This proposal does not prohibit the use of SHA-1 to generate issuerKeyHash or issuerNameHash values as currently required by RFC 5019. Includes minor formatting corrections.
