parcimonie

privacy-friendly helper to refresh a GnuPG keyring

parcimonie is a daemon that slowly refreshes a gpg public keyring from a keyserver. Its refreshes one OpenPGP key at a time; between every key update, parcimonie sleeps a random amount of time, long enough for the previously used Tor circuit to expire. This process is meant to make it hard for an attacker to correlate the multiple performed key update operations. See the included design document to learn more about the threat and risk models parcimonie attempts to help coping with. parcimonie also ships a deprecated desktop applet that allows one to monitor the background daemon's activities with a graphical user interface. It may or may not work for you, depending on your desktop environment.
