Let's add a decentralized GitLab proof to your OpenPGP keys. This will also work on self-hosted instances.
Post a GitLab proof message
Log in to gitlab.com or any other GitLab instance (your profile must be "public", not "private") and click on New project.
Set the project name to a name of your choosing.
Set the project slug to gitlab_proof.
Set the project description to (make sure to replace FINGERPRINT):
[Verifying my OpenPGP key: openpgp4fpr:FINGERPRINT]
Optional: edit the README.md to this:
This is an OpenPGP proof that connects my OpenPGP key to this GitLab account. For details check out https://docs.keyoxide.org/advanced/openpgp-proofs/
After creating the project, copy the link to the project.
Update the PGP key
First, edit the key (make sure to replace FINGERPRINT):
gpg --edit-key FINGERPRINT
Get a list of user IDs and find the index of the one to assign the notation to:
Select the desired user ID (make sure to replace N):
Add a new notation:
Enter the notation (make sure to update with the link to the project copied above):
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
And you're done! Reload your profile page, it should now show a verified GitLab account.
