Adding a DNS proof

Let's add a decentralized DNS proof to your OpenPGP keys.

Update DNS records for your website

Add the following TXT record to the DNS records of the (sub)domain you want to prove control over (make sure to replace FINGERPRINT):

openpgp4fpr:FINGERPRINT

No specific TTL value is required.

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

gpg --edit-key FINGERPRINT

Add a new notation:

notation

Enter the notation (make sure to replace DOMAIN, don't include https://):

proof@metacode.biz=dns:DOMAIN?type=TXT

Save the key:

save

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
