We want to offer an option for regularly refreshing OpenPGP certificates.

It should be configurable:

• how often this happens, e.g. every day, every second day, etc but no period longer than every week
• how long (plus a random additional time period) after the start of Kleopatra the process should start

The user should normally not be notified, but a log would be good, so that it is possible to check if the process did run and if there were errors (keyserver not responding, no WKD configured…). An option to export the updated certificates should be made available, so that the information can be transferred to an offline computer.

If any revocations were retrieved, the user should be informed via a dialog window.
