Yubikey Ownership Proof

This document proves ownership of two Yubikeys by the same person.

Yubikey A (Primary)

  • Key ID: C85159D1D1496A315A7E01466BF45F815F702663
  • Card Serial: 15906842
  • UID: Nathan Berkopec (5 NFC Master) [email protected]

Yubikey B (Secondary)

  • Key ID: 3C3E54D4F0A2218E1C1AA1A2ED9299DFE432C3A1
  • Card Serial: 19194228
  • UID: Nate Berkopec (Yubikey B) [email protected]

Proof of Ownership

Yubikey B's public key has been signed by Yubikey A, establishing that both keys are controlled by the same person.

Verification Steps

  1. Import the signed public key:

    curl -s https://gist.github.com/[username]/[gist-id]/raw/yubikey-b-signed.asc | gpg --import

  2. Verify the signature:

    gpg --check-sigs 3C3E54D4F0A2218E1C1AA1A2ED9299DFE432C3A1

  3. You should see that key 6BF45F815F702663 (Yubikey A) has signed key ED9299DFE432C3A1 (Yubikey B).
