Hello TAG (and W3C chairs, copied),

I am contacting you as chair of the Web Crypto WG.

Last week in TPAC, we have been addressing the question whether the Web Crypto API should be usable only with secure origin [1]. We have need encountering several problems while discussing, which were :

-          Does the TAG recommends a specific strategy (I heard from informal discussion with Mark Nottingham no, I heard from Alex Russel, yes) ?

-          Does the W3C has a common definition of  what is secure origin ?

-          Is there any possible granularity to require secure origin (e.g. use secure origin only for specific feature in a specification, which usage is particularly sensitive)?

-          What are the feedback from service eproviders on secure origin (we heard about Netflix, but what about the others) ?

-          Is there any easy migration path for W3C (and browser makers) to issue specifications without requiring secure origin, and later moving to mandating it.
FYI, in the end, we concluded that, provided the number of questions, provided the low interest of browser maker in the room to support secure origin, the fact that the web crypto is about to move to CR, we would not mandate the secure origin in the Web Crypto API.

I believe that those questions could apply to any new sensitive feature currently under development in W3C. Without asking the TAG to solve all the secure origin related bugs raised in github/tracker/bugzilla W3C WG, I think that it would be highly productive if the TAG could centralize and publish information helping to solve questions above. This would help all  W3C WG to take the decision to endorse or not secure origin, based on a common level of understanding of what it is.

Do you think this would be feasible in a short term ?
(I let other chairs confirming if they need or not such common framework).

Regards,
Virginie
Chair of web crypto WG
