Re: [Secdispatch] [dispatch] HTTP Request Signing

Thanks for the pointer to the BoF, I hadn’t seen that one. I am familiar with the draft you linked though: The main difference is that the draft in question is for a signed response, whereas the draft(s) I’ve pointed at are for a signed request. Yes, they ought to be aligned, but the WG in question seems to be much more focused on packaging responses together than dealing with requests. If that new group also wants to take on request signing, then by all means let’s do it there. But it’s not as clean a match as it might seem on the surface, I think.

I’m targeting both dispatch groups because this represents the intersection of both areas, and I think we’d get different perspectives from each side that we should consider.

Lately, though, I’ve been seeing a lot of renewed effort in different sectors, and in particular the financial sector and cloud services, to have a general purpose HTTP message signing capability. As such, I think it’s time to push something forward.
