Deleting Proofs using GnuPG

Over time, you may need to delete proofs. Changing proofs can be achieved by deleting proofs and adding new ones.

Delete all proofs

First, edit the key (make sure to replace FINGERPRINT):

gpg --edit-key FINGERPRINT

Launch the notation prompt:

notation

Enter the ‘none’ notation to delete all notations:

none

Save the changes:

save

Delete one of your proofs

First, edit the key (make sure to replace FINGERPRINT):

gpg --edit-key FINGERPRINT

Launch the notation prompt:

notation

Enter the - (minus) symbol followed by the proof you want to delete. Make sure you type the proof exactly like it is in your key.

-proof@metacode.biz=dns:yourdomain.org?type=TXT

To make it easier to enter the right proof, you could first list all proofs and simply copy the proof (including “proof@metacode.biz=”) you want to delete.

Upload the key to WKD or use the following command to upload the key to keys.openpgp.org (make sure to replace FINGERPRINT):

gpg --keyserver hkps://keys.openpgp.org --send-keys FINGERPRINT
