[ANNOUNCE] Key Signing Party at KVM Forum 2013

[ANNOUNCE] Key Signing Party at KVM Forum 2013

[Anthony Liguori]

I will be hosting a key signing party at this year's KVM Forum.

http://wiki.qemu.org/KeySigningParty2013

Starting for the 1.7 release (begins in December), I will only accepted
signed pull requests so please try to attend this event or make
alternative arrangements to have someone sign your key who will attend
the event.

I will also be attending LinuxCon/CloudOpen/Plumbers North America if
anyone wants to have another key signing party at that event and cannot
attend KVM Forum.

Regards,

Anthony Liguori

keyserver.cryptnet.net seems broken.  I get connection refused when
syncing to it.  On port 80 it serves up a default Fedora apache page.

Is there an alternative key server you'd like to use?

Same here. Do we have alternative key server now?

I think the key servers sync to each other anyway,
so it doesn't matter much which one you pick.

The wiki still says "Day/Room TBD" and I don't see it on the published
KVM Forum schedule.  Has this been determined yet?

Can somebody provide known-good instructions for how to
sign and return keys? I looked on the web and found four
different possible ways to do this (most notably, there
seems to be a split between "just send keys back to
the keyserver" and "email something to the keyowner"),
and as usual gpg's UI is hopelessly opaque and confusing :-(

I've pasted my key-signing bash script below. At the (few) key signing
parties I've been to, the idea was "upload to keyserver as a personal
favor to those you already know and like, email signatures encrypted
with the recipient's key to those you've only just met at the party".

Assuming a text file with one key signature per line, the bits that
are commented out were used to import keys and display fingerprints
for comparison with the stuff we had printed on paper and verified at
the party. The uncommented bits will do the signature export,
encryption with the recipient's key, and emailing.

Similarly, here's some advice I've used after previous key-signing
parties; I personally like how 'pius' automates the sending of
signatures to other recipients.

I had a look at 'pius' since some of the signed-key
emails I've received used it; however I couldn't find
any way to make it write the emails to a file for
sending elsewhere (my machine with the gpg key has
no external SMTP access). Similarly, 'caff' claims
to support that but doesn't actually seem to in
practice.
