MIT Building E-51, Room 315

A talk on ENIGMA and crypto history, followed by our annual PGP keysigning party. Register your key in advance!


“A short history of cryptology, Part I: Classic”

Bill gives a short talk on the history of cryptology, followed by our annual PGP/GnuPG keysigning party.

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 purpose of the meeting is to authenticate each other, i.e. verify everybody's key ids and key fingerprints. Participants sign each others' keys offline.

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.
