2003 | Keysigning will run a PGP/GPG keysigning session! This session requires a little preparation before coming to so as to make this run as smooth as possible. This is a completely optional event at LCA. You don't have to know (or care) what a keysigning party is to attend LCA. This page is just as a pointer for those who would like to exchange encryption keys.

First, some background pointers for the unfamiliar: GPG/PGP is a cryptographically strong way of either signing or encrypting something. It is based on public-key asymmetric cryptography. PGP was created by Phil Zimmerman, and later purchased by Network Associates. The Gnu Privacy Guard (GPG) is an open source equivalent program.

For information on what keys are and how to make them, see the FAQ and Documentation on the GPG web site.

This keysigning party will be run similar to this GPG Keysigning HOWTO (local copy v1.0.4). To participate in the LCA keysigning, you need to do the following:

  • Email your public key to Not just the fingerprint, but the whole key as it currently stands.
  • Print out your GPG fingerprint and bring it with you so you can refer to it later.
  • Bring with you sufficient photographic ID that you can prove to others that you are who you claim to be (drivers' licence, passport, etc).

All keys sent to the email address will be compiled into one file, and this will be signed by LCA. All fingerprints will be made available on one sheet for people to take with them from the keysigning. Each person wishing to exchange keys will turn up to the keysigning, get a copy of the key sheet, verify their key is correctly represented, and show the other people their ID. Each person then makes a decision on whether they think the key is valid and the person is whom they claim to be, and can then chose to sign it, or not, as the case may be.

To sign a key, see section 3.6 of the gpg-party HOWTO.

For any questions, email the address, and the keysigning administrator will help you.
