KSP Linuxwochen Linz 2015

The following website addresses all people who (i) attend the Linuxwochen Linz 2015, (ii) possess a PGP key, and (iii) want to participate in a key-signing party where all participants sign each others’ key.

If you missed the deadline for key submission, you can still participate in the key signing by the traditional way.

Instructions

It is very important that everyone precisely follows these instructions.

1. Before the party.

   • Until Thu, May 28, 21:59 CET:

     Submit your key to the keyserver¹ by calling

         gpg --keyserver ksp-lwlinz2015.sthu.org --send-keys KEYID
     

     with your KEYID. You can check whether uploading worked by inspecting ksp-lwlinz2015.txt. It is regenerated when a key is submitted and should contain your key.²

     If you want to create a new key (because your current key expires soon, or you want a more secure key, etc.) then now is a good time.

   • I will compile a text file with all submitted keys and send it to you.

     You need to print the file and follow the instructions on it. At the party, I will announce the correct checksum. Everyone needs to check the checksum such that we can be sure that we all have exactly the same file printed. You should also check that the fingerprint of your key on the list is correct.

   • If you could not submit your key until the deadline, you can still participate in the key signing, but not in the Zimmermann–Sassaman protocol. Just bring a sufficient number of printouts of your fingerprints with you, e.g., by printing the output of

         gpg --fingerprint KEYID
     

     All participants can exchange fingerprints and verify IDs in the traditional way after we executed the protocol. In fact, it also makes sense for people that do participate in the Zimmermann–Sassaman protocol to bring printouts of their fingerprints with them.

2. At the event.

   • You need to bring your (!) printed list and a pen. You must not copy the list of someone else.
   • You need to bring a document of identification³ (e.g., passport, driving license) that contains a photo of you.
   • I will moderate the procedure by which we will efficiently check each others’ ID document and the validity of the fingerprints.

3. After the event.

   • Sign the keys of those owners where you checked the identity and send them their signed keys back by mail.
