PGP Subkey refresh for Yubikey

This is my workflow and might not be applicable to yours. I am not rotating subkeys but only extending their expiration.

  1. Boot to Tails
  2. Go to the place of backedup GPG folder and run export GNUPGHOME="$(pwd)"
  3. gpg --list-keys
  4. export KEY="<<KEYID>>"
  5. gpg --edit-key $KEY
  6. key 1 and repeat for 2 and 3
  7. expire and set the new expiration
  8. save
  9. gpg --output public.pub --armor --export $KEY
  10. Go to online machine
  11. gpg --import public.pub
  12. gpg --send-key $KEY
  13. Update website with new key
