Forgive my lack of know-how, but does this theoretically mean I could download this _signed package_ to my computer along with the signature and use it later to prove that the information was provided by the source according to the signature?
I'm not quite following which parts were or weren't needed for what's been enabled in the post here, for the usecase of delivering a single offline package that can be opened like a website, is there something that works yet? Or a repo I should be following other than the spec?
Once I can create webpackages and deliver them to clients a lot of thing I want to do become hugely easier and nicer.
Oh interesting! I'll see what I can find there, thanks!
I also had a look in the blog and the "progressive web apps" might be the right thing to look at. There's probably something subtle that's different but I think I can use these to solve the actual problem I have.
edit - damn, I don't think this is right at all. Frustrating as it seems pretty perfect but I have to serve from my own domain for 30s before a user can install it :( I just want a single file way of delivering web content! It seems like all the features are basically there, just with restrictions to focus on different use cases.
You could prove the document was signed using the source's private key. That does prove the document was signed by the source if you can prove that only the source had access to the key.
