Tor 0.2.0.26-rc (Testing branch)
05-13-2008
Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. It provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals can use it to keep remote Websites from tracking them and their family members. They can also use it to connect to resources such as news sites or instant messaging services that are blocked by their local Internet service providers (ISPs).

parcimonie - privacy-friendly helper to refresh a GnuPG keyring VERSION
Version 0.7.1 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://keys.indymedia.org You obviously can choose your preferred keyserver here; if using hkps:// (which would be our second choice behind hkpms://), your GnuPG installation should support HPKS; 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://keys.mayfirst.org/ 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://zimmermann.mayfirst.org" 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.
