Get Your OpenPGP Key Signed

Once you have:

... you can ask others to sign your key.

Remember that to have someone sign your key, you must prove to them that:

  1. This is your key.
  2. You really are the person you say you are.

How to prove a key is yours

Create a printed identification of your key using the fingerprint of the key. The fingerprint is a summary of a key, and allows anyone to positively identify a key held on a key server.

To get the fingerprint of your key use the gpg --fingerprint command as follows:


gpg01@wally:~$ gpg --fingerprint
/home/gpg01/.gnupg/pubring.gpg
------------------------------
pub  1024D/66712F41 2003-08-17 GPG User 01 (OpenSkills developer) {gpg01@openskills.org}
     Key fingerprint = 361C D0EE C6E5 AEDE A774  EEE6 BF71 C1E3 6671 2F41
sub  1024g/B1545A3E 2003-08-17

The simplest thing to do is cut the above text into a word processor document. Make a table in your document of as many rows and columns that will fit, and copy the fingeprint information into each cell of the table. Print out the document, and cut up the sheet in to slips with one copy of the fingerprint information on each. Give one of these slips to each person you are asking to sign your key.

Each slip should look something like this:

 pub 1024D/66712F41 2003-08-17 GPG User 01 (OpenSkills developer) {gpg01@openskills.org}
Key fingerprint = 361C D0EE C6E5 AEDE A774 EEE6 BF71 C1E3 6671 2F41

Some people add this fingerprint information to their business cards, which makes getting your key signed even easier.

How to prove you are who you say you are

It is up to the individual how careful they are, but be ready for people to ask you to show them photo id (Drivers license or passport). Also be ready for people to send an email to you just to check that the address (as shown with the fingerprint above) really is yours.

Be wary of people who do not check carefully. If they are sloppy checking your identity, they may well be sloppy checking in general.
