MS ends the support of TLS prior to 1.2 in october. https://support.microsoft.com/en-us/help/4057306/preparing-for-tls-1-2-in-office-365 Is TLS 1.2 supported on Discourse?

@sam @mpalmer should we even be supporting TLS v1? That seems positively ancient .. as of 2014 all major browsers supported TLS v1.2?

I’m happy to nuke older browser support if you want. It’d reduce the cipher list, too, because most of the entries in there are to support older browsers. The main reason I didn’t go “full strict” last time I reviewed those settings is because while you can gracefully degrade UI on older browsers,…

It looks like we are safe to disable TLS V1 at least because we don’t support IE10, and IE11 supports TLS V1.1 [augurar] Should I disable TLS 1.0 on my servers? tls, webserver, pci-dss, known-vulnerabilities asked by augurar on 07:41PM - 23 Nov 15 UTC …

Oh but Matt’s point of you don’t even get an error page or anything except for “broken cert” kind of stands. I think that given: TLS 1, when properly configured has no known security vulnerabilities. Newer protocols are better designed and better address the potential for new vulnerabilities. I…

It is pointless though any browser so old that it only supports TLS v1 will not load Discourse’s advanced JS anyways.

Sure, but I wonder, does this mean we want to remove? https://github.com/discourse/discourse/blob/master/vendor/assets/javascripts/browser-update.js.erb

Maybe, looking at the old dates there and market share of ancient stuff..

Just as a reference of what others are doing, GitHub (which admittedly has an audience that is rather likely to keep browsers up to date) is disabling TLS 1.0 and 1.1 now: [画像] Weak cryptographic standards removal notice Last year we announced the deprecation of several weak cryptograph…

We should remove tls v1 @mpalmer — that seems quite safe to me.
