PGP key signing at NANOG 29 in Chicago [REVISED]

[the original mail I sent had the wrong date in the third paragraph; this one has the right date. sorry about the confusion.]

There will be a brief introduction to PGP key signing presented in the General Session at 11:15 a.m. on Monday, entitled "Building a Web of Trust".

New for NANOG 29: you will find stickers available at the checkin desk which which you can stick on your name tag. The red dot means "I sign keys"; the idea is to make it easier to identify people for whom PGP key signing is interesting when you meet them outside the signing party.

Key Signing Party

We will be holding a PGP Key signing party at the NANOG 29 meeting in Chicago. We have been scheduled to meet on Monday 20 October, after the ISP Security and NSP-SEC BOF, at around 9pm in Salon F. If the BOF runs on, we will delay a little.

The procedure we will use at the key signing party is as follows:

1. People who wish to participate should email an ASCII extract of their PGP public key to <> by noon on Monday 20 October 2003. Please include a subject line of "NANOG PGP KEY", and please avoid MIME-encrypting your e-mail if possible.

The method of generating the ASCII extract under Unix is:

   pgp -kxa my_email_address mykey.asc (pgp 2.6.2)

   pgpk -xa my_email_address > mykey.asc (pgp 5.x)

   gpg --export -a my_email_address > mykey.asc (gpg)

If you're using Windows or Macintosh, hopefully it will be Intuitively Obvious (tm) using the GUI interface how to generate an ASCII armored key that begins:


2. After 6pm on Monday, you will be able to fetch a complete key ring with all of the keys that were submitted from <> (an ASCII copy will also be available from <>).

3. At 9pm, come prepared with the PGP Key fingerprint of your PGP public key; we will have handouts with all of the key fingerprints of the keys that people have mailed in.

4. In turn, readers at the front of the room will recite people's keys; as your key fingerprint is read, stand up, and at the end of reading of your PGP key fingerprint, acknowledge that the fingerprint as read was correct.

5. While everybody is in the room together, it's a good chance to verify the identities of people whose key fingerprints you have checked, if you don't already know them personally. You might want to bring photo id with you (drivers licence, passport, etc) to make it easier for other people to confirm your identity.

6. Later that day, or perhaps when you get home, you can sign the keys corresponding to the fingerprints which you were able to verify on the handout; 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.

7. Submit the keys you have signed to the PGP keyservers. A good one to use is the one at MIT: simply send mail containing the ascii armored version of your PGP public key to

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 handout, and then take the handout home and sign the keys later.
