NAME

       parcimonie - privacy-friendly helper to refresh a GnuPG keyring

VERSION

       Version 0.8

SYNOPSIS

       parcimonie [options]

DESCRIPTION

       parcimonie is a daemon that slowly refreshes a GnuPG public keyring from a keyserver.

       Its refreshes one 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 design.mdwn document to learn more about the threat and risk models parcimonie
       attempts to help coping with.

USAGE

       1. Configure GnuPG to be able to use a keyserver.

       You can skip this section if you already have configured a keyserver in ~/.gnupg/gpg.conf.

       Else, add to your gpg.conf something along these lines:

               keyserver hkp://pool.sks-keyservers.net

       You obviously can choose your preferred keyserver here; if using hkps:// (which would be
       our second choice behind hkpms://), your GnuPG installation should support HKPS; on Debian
       systems, enabling such support is done by installing the gnupg-curl package; see those web
       pages for help with GnuPG hkps:// configuration:

               http://sks-keyservers.net/overview-of-pools.php#pool_hkps
               http://keys.indymedia.org/

       You may want parcimonie to use a different keyserver than the one your usual GnuPG
       invocations do. This can be achieved by passing to parcimonie a command-line option such
       as:

               --gnupg-extra-arg "--keyserver=hkps://hkps.pool.sks-keyservers.net"

       2. Run "parcimonie --verbose".

       3. Check the output for misconfiguration or bugs.

       4. Once happy, start the daemon without the --verbose option.
          Note: the Debian package automatically starts the daemon with your X session.
          For example, GNOME users can configure its startup from the
          "System -> Preferences -> Startup Applications" menu.

OPTIONS

       The following command lists available options:

           parcimonie --help

   Tor configuration vs. --minimum-lapse-time
       In case you set the Tor MaxCircuitDirtiness setting yourself, you probably want to pass
       parcimonie a matching --minimum-lapse-time option so that subsequent key fetches use
       different Tor circuits.

       Just make sure this remains true:

               minimum-lapse-time >= Tor MaxCircuitDirtiness

   hkpms://
       We recommend using hkpms; see http://web.monkeysphere.info/ for details. When a hkpms://
       keyserver is being used, one needs to do two additional steps since gpgkeys_hkpms does not
       work in the torsocks wrapped environment parcimonie uses by default to run gpg.

       Torify gpgkeys_hkpms

       Just add the following line to gpg.conf:

           keyserver-options http-proxy=socks://127.0.0.1:9050

       Hey, parcimonie, gpg is already torified

       Pass the --gnupg-already-torified switch to the parcimonie daemon command-line. parcimonie
       will then rely on the keyserver-options previously added to gpg.conf, and won't attempt to
       torify gpg connections itself.
