Re: gnome-keyring Secrets dbus api

I was trying [1] and waiting to get this stuff hosted on freedesktop.org
so I'd have  something to link you to when I answered... But sadly, no
such luck yet :(

That's very cool!

I believe in the case of DH we truncate the resulting key to the
appropriate length. This is what we do in gnome-keyring. I'd like to
double check that this is the correct thing to do.

Yes, it's a bug. I believe the code is correct, but the compiled version
there is wrong. I want to update the spec, and get hosting on
freedesktop.org to put it. Hence my frustration :(

Yes, we need to work on that. Haven't had time.

I'm glad that you like it, and even happier that you're playing with it
and getting involved. There's still a lot to do [1], but I hope we can
make steady progress and get a real solid foundation for this stuff on
the linux Desktop.
