Encryption stuff in need of solutions

I think having to explicitly submit the password is okay, I have not
encountered any auto-submitting password dialog anywhere yet.
I guess we can plausibly make an exception here.

About cancel buttons I'm still undecided. What I am sure about, though, is
that we have to do it consistently. Either all of our dialogs 
have a "cancel" or "close" button or none of them.
I don't strongly favor either, we just have to decide.
