PGP keysigning party. Register your key in advance to participate!


Abstract:

Crypto News Review
Annual Historical Vignette

Re Keys for Key-signing, we should announce (in addition to what we've
said before)

* We will NO LONGER sign RSA or DSA 1024b keys (or shorter). Obsolete.
* We will NOT sign RSA 2048b keys without expiration dates or
expiration dates beyond 2020.
* Use RSA 4096 for gpg2 --gen-key

Notes
* If concerned about well-capitalized massive factoring dictionaries,
subtract a small multiple of 8 bits to get a size that is not standard
and thus won't be dictionaried.
* Alas the one trustworthy ECC curve, ed25519, is supported only in
GPG 2.1.7+ (gpg2)
only with developer version of a library and in experimental mode.
* But do start using ed25519 for efficiency and security with any SSH
servers updated to handle it
ssh-keygen -a 100 -t ed25519 # EdDSA Twisted Edward curves.

We hold our annual 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 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
subkeys.pgp.net.

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.

ARM chips, the designs span from four nodes to twelve, and from $150 to

be sure to bring interesting questions that no one really knows the
answer to!
