DigiCert supports banning SHA1 across the board. We are no longer supporting SHA1 signatures for services related to certs trusted by Mozilla.

It would require very little effort for us to reconfigure these roots and intermediates so that they use SHA-256 instead. We expect that switching to SHA-256 will bring minimal, perhaps even zero, disruption to relying parties. Therefore, we'll be happy with whatever sunset date Mozilla chooses. ________________________________ From: [email protected]<mailto:[email protected]> <[email protected]<mailto:[email protected]>> on behalf of Ben Wilson <[email protected]<mailto:[email protected]>> Sent: 02 February 2022 03:59 To: Ryan Sleevi <[email protected]<mailto:[email protected]>> Cc: [email protected]<mailto:[email protected]> <[email protected]<mailto:[email protected]>> Subject: Re: Policy 2.8: MRSP Issue #178: Sunset SHA1 CAUTION: This email originated from outside of the organization.

Yes. It is preferable that discussion take place here. However, a survey would still be public, as they have been in the past, and the CCADB would collect all of the responses in a table format. Oh, for sure :) I just know that the surveys have historically had delays or had confusion by CAs in interpreting questions, and the survey approach somewhat predates the m.d.s.p. participation requirement. I totally realize that it has benefits for bringing direct awareness, but I raise it to try and understand if the expectation is to always have the two parallel paths for soliciting feedback, or if it might just be sufficient to email blast CAs to say "Hey, here's the discussion, to send feedback, please participate here". That, I think, might achieve the goal of highlighting the importance, while still centralizing some of the conversation :) Just a thought -- You received this message because you are subscribed to the Google Groups "[email protected]<mailto:[email protected]>" group.
