Kelvin Yiu of Microsoft made the following motion, and Kirk Hall from Trend Micro and Ryan Sleevi from Google have endorsed it.

Reason for Ballot

Over the last year or two, several application software providers have announced deprecation of the SHA-1 algorithm in their software.

— Motion Begins —

  1. In the Baseline Requirements, insert the following new section 9.4.2:

9.4.2 SHA-1 Validity Period

Effective 1 January 2016, CAs MUST NOT issue any new Subscriber certificates or Subordinate CA certificates using the SHA-1 hash algorithm. CAs MAY continue to sign certificates to verify OCSP responses using SHA1 until 1 January 2017. This Section 9.4.2 does not apply to Root CA or CA cross certificates. CAs MAY continue to use their existing SHA-1 Root Certificates. SHA-2 Subscriber certificates SHOULD NOT chain up to a SHA-1 Subordinate CA Certificate.

Effective 16 January 2015, CAs SHOULD NOT issue Subscriber Certificates utilizing the SHA-1 algorithm with an Expiry Date greater than 1 January 2017 because Application Software Providers are in the process of deprecating and/or removing the SHA-1 algorithm from their software, and they have communicated that CAs and Subscribers using such certificates do so at their own risk.

  1. In Appendix A of the Baseline Requirements – Cryptographic Algorithm and Key Requirements (Normative), add this note under Table 2, Subordinate CA certificates:

* SHA-1 MAY be used with RSA keys in accordance with the criteria defined in Section 9.4.2.

And amend this note at the end of each of the 3 tables.

* SHA-1 MAY be used with RSA keys in accordance with the criteria defined in Section 9.4.2 until SHA-256 is supported widely by browsers used by a substantial portion of relying-parties worldwide.
