Adding a GitLab proof

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://keyoxide.org/guides/openpgp-proofs

After creating the project, copy the link to the project.

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:

list

Select the desired user ID (make sure to replace N):

uid N

Add a new notation:

notation

Enter the notation (make sure to update with the link to the project copied above):

proof@metacode.biz=https://gitlab.example.com/USERNAME/gitlab_proof

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

And you're done! Reload your profile page, it should now show a verified GitLab account.
