Forum Infrastructure Report

Jos Purvis gave the update.

There was a very brief discussion on the GitHub digest and Corey has started poking into implementing the automated digest email digest to GitHub activity to each of the working groups. He just needs access to send from the account, which Jos is going to be getting him.

Code Signing Working Group Update

Bruce Morton gave the update.

CSC-12 is in the voting period. Working on a ballot for subscriber key protection. Next priority is to update the code signing service requirements. Also want to complete changing CSBRs to the RFC 3647 format.

S/MIME Working Group Update

Stephen Davidson gave the update.

Continuing the discussion on the validity periods. Apple has settled on 825 days. Would be allowable for the 1 legacy policy, which is intended as kind of a short term bridge to allow more of the ecosystem to be pulled into this auditable framework. But the intent is that it would disappear over time. It’s really a debate on the balancing of kind of the desire for automation and policy agility, versus kind of acknowledging the heavy usage of tokens and so forth. There has been some willingness on the part of a certificate consumers to consider 2095 day legacy period, as long as there is a hard date that it would be deprecated. So that’s really an ongoing discussion. We’ve also had a discussion of the contents of the version 1, primary deliverable. Certainly for those who would like to see the evolution of that document, it is publicly available out In the cab form, GitHub repository, there’s, the S/mine section and you would be looking for the SBR. There’s a version called the Pre SBR that is the working draft. The next step in our list of discussions there, was a specific request from a certificate consumer asking to have, as a focused discussion, the topic of external enterprise RAs. So that’s what’s next on our agenda.
