Nope, not in our experience. I'm hoping Jody can share his graph, but much of our 'breakage' experience was from sites where the CA waited to stop issuing SHA-1 certs until it was explicitly forbidden - that is, they did not even default to SHA-256, or made it considerably *more* difficult for their customers to obtain SHA-256 signed certs ===> Ryan, You said you hope Jody can share his graph. Do you mean the discussion in last Fall Redmond F2F meeting as the minute below in Mozilla's news section? https://cabforum.org/2016/10/19/2016-10-19-20-f2f-meeting-39-minutes/#Mozilla Side note based on comments from Microsoft •MS shows 20M sites with SHA-1 where as FF counts traffic •Why do this now vs. waiting a year, that’s the rush? •Wants to work with other browsers on timing. Google might have different pain thresholds. Goal is to figure out we get proper user feedback and that stakeholders are not screaming. The no-SHA-1 requirement came in force January 2016 - not 2015. We passed the Ballot in 2015, following Microsoft's announced deprecation in Nov 12, 2013 - https://technet.microsoft.com/en-us/library/security/2880823.aspx ==> The SHA-1 sunset ballot was passed on 16 October 2014, not 2015. Please see https://cabforum.org/2014/10/16/ballot-118-sha-1-sunset/ I think most CAs offer their cusomers to migrate SHA-1 SSL certificates to SHA 256 SSL certificates for free. Try their best to call out and e-mail to the customers to encourage them. Sincerely Yours, Li-Chun Chen Chunghwa Telecom Co.
