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):
No specific TTL value is required.
Update the PGP key ¶
First, edit the key (make sure to replace FINGERPRINT):
gpg --edit-key FINGERPRINT
Add a new notation:
Enter the notation (make sure to replace DOMAIN, don’t include https://):
Save the key:
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
