Not necessarily. But even if it is, the attacker has to know where to
find the private key and run non-trivial code to use it. The risk is
smaller than plopping the secret data in plain view.

Yes, and we've discussed how ELisp makes that hard, so this will require
work at the C level. It's not trivial, absolutely.

That's a possibility but not my target currently.

We have KDE+GNOME in auth-source already, through the Secrets API. We
also had an attempt to provide an interface to the Mac OS X keychain
last year, but I don't think it was fruitful.

Yes, I've followed Jeff King's patches with great interest, although I
was absolutely swamped last year and could not test them as I wanted to.
I intend to work on integrating VC and Magit with Git's credentials,
probably with auth-source support.
