8th International Linux-Kongress · Nov 28-30 2001 · Enschede/The Netherlands
Key Signing Party
We will be holding a PGP Key signing party at GNU/Linux Kongress 2001.
We have been scheduled to meet at 18:00 on Thursday, November 29, 2000.
The procedure we will use is the following.
- People who wish to participate should email an ASCII extract of their
PGP public key to <firstname.lastname@example.org> by Wednesday, November 21, 2001.
Please include a subject line of "LK 2001 PGP KEY", and please
do not sign or encrypt your email.
The method of generating the ASCII extract is:
gpg --export -a my_email_address > mykey.asc (gpg)
pgp -kxa my_email_address mykey.asc (pgp 2.6.2)
- By Friday, November 23, you will be able to fetch both the complete
keyring with all the keys that were submitted along with a text file
giving the fingerprint of each key on the ring. These files are here:
Take care to use a binary download mode or get the files as a tarball:
- At home, verify that the fingerprint of your key in lk2001.txt is correct.
Also compute the MD5 hash of lk2001.txt. One way to do
this is with md5sum invoked as follows:
% md5sum lk2001.txt
Just to be sure that you have no problems with the download, here is
the MD5 hash as we have calculated it:
MD5 = EC 51 8E F6 93 5F 68 D1 12 3C 66 B2 0A 79 06 C9
Note, that this is just a hint - you must do the check yourself.
- At the conference, come with the hash you computed, a hardcopy
of lk2001.txt an identity card and a pencil.
- A reader at the front of the room will recite the MD5 hashes of
lk2001.txt. Verify that the hash recited matches what you computed.
This guarantees that all participants are working from the same list
- In turn, each participant will stand and acknowledge that the fingerprint
of his or her key listed is correct. Mark the key verified on your
- Later that evening, or perhaps when you get home, you can sign the
keys corresponding to the fingerprints which you were able to verify
on the hardcopy; note that it is advisable that you only sign keys of
people when you have personal knowledge that the person who stood up
during the reading of his/her fingerprint really is the person which
he/she claimed to be.
- Submit the keys you have signed to the PGP keyservers. A good one to
use is the one of SurfNet simply send mail containing the ascii armored
version of your PGP public key to <email@example.com>.
Note that you don't have to have a laptop with you; if you don't have
any locally trusted computing resources during the key signing party,
you can make notes on the hardcopy, and then take the hardcopy home and
sign the keys later.
