Hi everyone: As Andrew suggested, I'd like to have an informal
keysigning at each KWLUG meeting.

We did this last month. Informal key signings are great for people who
already know each other and want to associate keyIDs with each other.

The informal keysigning consists of exchanging key fingerprints on slips
of paper generated with

  gpg --fingerprint 0xYOURKEYID

(and then copy'n'pasted several times on a page, printed, and cut into

or you could use

  gpg-key2ps 0xYOURKEYID > fingerprints.ps

(and then print fingerprint.ps and cut into strips)

For people who don't know each other well enough to trust exchanged
slips of paper there's a Formal Keysigning, which we'll be having at the
meeting on 2 December 2013.  Stay tuned here over the next month as I
spam the list with keysigning details.

If you want a bit of an advance on GnuPG/PGP information, the UofW
CSClub is having Hands On Seminar on Public Key Cryptography.  More info
on that meeting is at


See you all on Monday!
