CS50 Key-Signing Party Registration


Before you register

It is very important that you capture your public key fingerprint in a human-readable form. For example, if your key's e-mail address is user@domain.tld, you can run
% gpg --fingerprint user@domain.tld
The response should be something like 

pub  1024D/3970227D 2003-05-12 Sam User <user@domain.tld>
     Key fingerprint = 83D9 A36B 7DA5 3C2B 8EFD  6ADB B778 07E6 3970 227D
sub  2048g/2E465894 2003-05-12

If you use PGP, the command is:
% pgp -kvc user@domain.tld
and the output looks like this: 
Pretty Good Privacy(tm) Version 6.5.8
(c) 1999 Network Associates Inc.

Looking for user ID "user@domain.tld".
Type bits      keyID      Date       User ID
DSS   769/1024 0xA2F355EC 2005/04/23 *** DEFAULT SIGNING KEY ***
                                     Sam User <user@domain.tld>
          Key fingerprint =  21 52 CD 03 DF C5 16 2F  1C 8B A4 A1 D9 07 B6 B6  A2 F3 55 EC

You need to obtain your fingerprint from a trusted source (i.e., your key ring) and transport it securely to the key-signing party--perhaps in your wallet.

Registration

To register for the event, submit your public key to our temporary local key server. Here are your options:

Upload directly to the server

For example, if you use GPG and your key's e-mail address is user@domain.tld, submit via
% gpg --keyserver facloan14.fac.cs.cmu.edu --send-keys user@domain.tld
The response should be
gpg: success sending to `facloan14.fac.cs.cmu.edu' (status=200)
If you use a GUI PGP client, the server's hostname is facloan14.fac.cs.cmu.edu, it speaks the HKP protocol, and it's running on the standard port (11371).

Submit your key as ASCII-armored text

  1. Export your key using one of the following commands:
    % gpg --export -a user@domain.tld > mykey.asc (gpg)
    % pgp -kxa user@domain.tld mykey.asc (pgp 2.6.2)
    % pgpk -xa user@domain.tld > mykey.asc (pgp 5.x)
  2. Paste contents of the whole file, including the BEGIN and END lines, into the form below. Here's an example of what it should look like.
