No changes to the agenda.

4. Approval of minutes from previous teleconference

The minutes from the previous teleconference were approved and will be circulated to the public list.

5. Forum Infrastructure Working Group update

Jos provided the update. He will send an request to update meeting days/times because of some conflicts by participants. The WG has a draft ballot to re-charter the WG into a Forum Subcommittee. The WebEx situation was also resolved with the assistance of HARICA. Jos would check with the WebEx team if everything is in order.

Dean asked if we should switch to WebEx for the bi-weekly teleconference calls because he was experiencing some difficulties with Turbobridge web access. Other members did not have issues with Turbobridge and suggested using Skype to call the Turbobridge gateway. We can revisit this in the future if more members have difficulties with Turbobridge.

6. Code Signing Working Group update

Dean mentioned that the Code Signing WG discussed merging newly approved CS with EV CS document, because there is significant overlap. There was some discussion about audits around that. Invitations will be sent to auditors for the code signing meetings. Moving up SHA1 prohibition but there are legacy applications that need SHA1. It was discussed to move the original prohibition from January 2021 to May 2020. Working on a cleanup ballot.

A spreadsheet with contact information was created so that malware companies can use contact information for CAs that issue code signing certificates, even though this information is published in the CAs CP/CPS.

7. Follow-up on new S/MIME WG Charter

No update.

8. Any Other Business

Dean reminded Members that we now have 43 attendees and if anyone plans to attend F2F 48 and 49 to signup and update the participant tables on the wiki so that the hosts can plan ahead.

Dimitris and Dean said we should start working on the agenda for the F2F by the next meeting. We also don’t have any guest speakers for F2F 48 and perhaps we could find speakers that could connect remotely.

9. Next call

September 19, 2019 at 11:00 am Eastern Time.
