GPG Key Signing Party

When: Tue February 13, 2018 07:30 PM to 09:00 PM

Speaker: E. Frank Ball

Location: O'Reilly Media

It’s time for another GPG key signing. We had one in May 2003 & August 2014.

The point of this is to create a web of trust. By signing someone’s public key, you state that you have checked that the person that uses a certain keypair, is who he says he is and really is in control of the private key. This way a complete network of people who trust each other can be created. This network is called the strongly connected set. Information about it can be found at

Before the meeting:

  1. Generate a public/private keypair with the gpg --gen-key command (accept the defaults), see man gpg for more info.

  2. Upload your key to a keyserver:

    gpg --send-keys --keyserver
  3. Print out the key fingerprint with gpg --fingerprint Also include your full name, email address, and Key ID#. Bring this to the meeting, and optionally make extra copies to hand out.

  4. Email me at with the fingerprint, email address, full name, and Key ID. I’ll have a list of everyone’s info to hand out.

During the meeting:

Verify your GPG key fingerprint on the list I hand out and verify your identity (with photo ID).

After the meeting:

  1. Download the all of the keys for the fingerprints verified at the meeting

  2. Add them to your keyring

  3. Sign them

  4. Upload your key again.
