Re: Major Milestone: WebID over WebSockets

What I have initially had trouble understanding in Dave Longley's javascript implementation 
of WebID is how the keys generated in one server and save in a local datastore
get used from one server to another. That is never made clear  in any documentation I have

In a conversation some time ago with one of the developers, I learnt that essentially until
the browser supports javascript access to the local keystone there is a lot of jumping around
using perhaps even OAuth in the background. So that means that the protocols in the
background is in fact very complicated and probably very difficult to secure. Cryptography
is notoriously tricky to get right, and javascript comes itself with a huge number of security

But all is not lost

There is a group called the Web Crypto API that is being put in place

And they are just developing their charter. If browsers support apis to have
direct access to the crypto layer then of course those back end hacks won't be
needed and furthermore it will be secure, in which case one could use javascript
to do the WebID authentication perhaps to bring in web sites that don't have 
TLS (hopefully a slowly diminishing number with DNSsec deployment)

At the same time I think we can look at this work as a way to do proofs of concepts
to open a discussion with BrowserId which also needs such a web cryptography layer.

Is Dave participating in the Crypto API group? I think that would be very useful.
