About PGP

Pretty Good Privacy was developed by Phil Zimmermann in the 90s. PGP empowers people to take their privacy into their own hands. There's a growing social need for it. As Phil puts it:

"""It's personal. It's private. And it's no one's business but yours. You may be planning a political campaign, discussing your taxes, or having an illicit affair. Or you may be doing something that you feel shouldn't be illegal, but is. Whatever it is, you don't want your private electronic mail (E-mail) or confidential documents read by anyone else. There's nothing wrong with asserting your privacy. Privacy is as apple-pie as the Constitution."""

Keysigning Introduction

Keysigning is generally an O(N^2) algorithm, expensive to execute with large parties. It's n-squared because each participant has to ascertain for themselves if the person who wants them to sign their key, is actually them - which means everybody has to show their passport and key ID to each other person in the room - a tedious and slow process.

However, it is quite common to take a middle ground. One might believe it is acceptable to appoint one or more people whom everybody trusts to be honest, and allow them to ascertain the identity of each participant, and publish a list of identities to the other participants, making this essentially an O(N) problem to solve.

At OSD, we will offer such a linear key signing party. There will be a booth at the conference venue, where one can meet one or more of the organizers. You identify yourself with one, or better yet: two government issued ID cards (an EU travel pass, passport, drivers license), and show the organizer your public PGP key fingerprint (generally 8 hex-digits, ie 4DCA7E5E). They make note of your name, e-mail key ID, and which document(s) you used (but importantly: NOT the ID details like passport number!). See the Onsite instructions for more details.
