Once you change an uploaded key to a Vault one, the uploaded key will be deleted; this action cannot be undone.
In the Signing Key list of keys, go to the arrow next to the uploaded key you wish to change to Vault and click it.
This opens the Change GPG/RSA Key to Vault window.
From the Vault Connector dropdown list, select the Vault connector you wish to use for the key.
Enter the details for the key.
Click Test to test the configuration.
If the test is successful, click Add GPG (RSA) Key to save the new key.
