Re: Request for feedback: DOMCrypt API proposal

Someone else also asked me about TLS key extraction, I will have to add that to my list of research to do. Can you point me to any further reading?

Two things. First, I don't see that that follows and even if
it did it still would not necessarily be convincing. My idea
in pushing key extraction is to avoid loads of developers
re-inventing the TLS handshake (badly) at the application
layer. Secondly, mutual auth is a different (in practice)
hard problem that's also well worth trying to address.

If there's interest in that too, that's great, but these
things should not be seen as competing IMO.
