Pre-register your PGP key before the meeting!


Add your key to the keysigning party checksheet []

A key signing party is a get-together of people who use the PGP
encryption system with the purpose of allowing those people to sign each
others keys. Key signing parties serve to extend the web of trust to a
great degree. Key signing parties also serve as great opportunities to
discuss the political and social issues surrounding strong cryptography,
individual liberties, individual sovereignty, and even implementing
encryption technologies or perhaps future work on free encryption software.

The basic workflow of signing someone's key is as follows:

Verify that the person actually is who they claim to be;
Have them verify their key ID and fingerprint;
Sign their key;
Send the signed key back to them

At the meeting, we go through the first two steps. Each person who
preregistered their key will announce their presence and then read off
their key ID and fingerprint, so everyone can verify that their copy of
the list of keys is correct. Once we've run down the list, we line up,
and each of us examines everyone else's photo IDs to verify that they
are who they claim to be. After the meeting is over, each participant
can then retrieve the keys that they've personally verified, sign those
keys, and send the signed keys back to their respective owners.

In order to complete the keysigning in the allotted time, we follow
a formal procedure as seen in V. Alex Brennen's "GnuPG Keysigning Party
HOWTO", attached below. It is strongly advised that if you have not been
to a keysigning party before, you read this document. We're using the
List-based method for this keysigning party, and the keyserver at

It is essential that, before the meeting, you register on the
signup form listed in the attachments. You should bring at least one
picture ID with you. You must also bring your own printout of the report
on that page, so you can check off the names/keys of the people you have
personally verified.

The list will be printed on Wednesday afternoon, the day of the
meeting; be sure to register your key for the keysigning before that.
The official cutoff time is 3:00 pm.


Jeff works at MIT in the Information Services and Technology
Department (IS&T). For more then 20 years he's managed MIT's Internet
presence. He also built a significant portion of MIT's Security
Infrastructure including its X.509 certificate deployment. MIT is
probably has one of the largest deployments (and certainly the oldest,
dating back to 1996) of X.509 client Certificates.
