HeaderCleaner is a small SMTP server plugin that will only allow a set of predefined headers in an outgoing email message and will strip all other headers from the message. This is meant to improve your privacy and better protect the mail handling server. This version is made for Communigate-Pro, but can be adapted for other systems.
GTK+ Recent Files Scrubber is a compact, lightweight Python script which uses GTK's RecentManager to watch for updates to all globally-available "Recently Used" lists (the ones which appear in Open dialogs and the like) and filter out anything in the folders you blacklist. Blacklist entries are hashed to make reading the blacklist not worth the effort.
Fluxfont is a specialized tool that attempts to tackle the privacy concerns raised by the possibility to collect information about the fonts installed on a system. Such information can be used to uniquely identify a system. With Fluxfonts, new fonts are randomly created and removed to prevent the same fingerprint from being recreated.
ecca-proxy is a Web proxy server that transparently handles Eccentric Authentication key and certificate management.

The proxy handles the difficult cryptographic details and provides an easy to use interface to the user.
The goal of Cheix USB is a Linux image executing from a USB storage device into a running OS, either Linux or Windows, so that the host machine does not have to support booting from the USB device. The root filesystem and boot partitions are read-only to preserve the USB device. All writes are done in a tmpfs. The only writes to the USB storage device are those explicitly made by the user. Cheix's ISO can currently be used to create either a bootable USB or a hard-drive installation.
Whonix is an anonymous general-purpose operating system based on Virtual Box, Debian GNU/Linux, and Tor. By design, IP and DNS leaks are impossible. Not even malware with root rights can find out the user's real IP/location, because Whonix consists of two (virtual) machines. One machine solely runs Tor and acts as a gateway, called Whonix-Gateway. The other machine, Whonix-Workstation, is on a completely isolated network. Only connections through Tor are possible.
