Keylookup is a perl script to search keyservers for GnuPG/PGP Keys and import them into your keyring.
Echolot is a Pinger for anonymous remailers.
Mixmaster is a type II anonymous remailing protocol and network. Remailers provide protection against traffic analysis and allow sending email mail anonymously or pseudonymously. There are currently (May 2002) about three dozens functional mixmasters in the Mix Net most running either the Reliable (on Microsoft Windows) or the (non-free) Mixmaster v3 software.
This project improves and bugfixes the current Mixmaster v3 software. In the long run a rewrite is planned.
Curious what's on my book shelf? See for yourself.
awm is Weasel's mail archiver for Maildir style mailfolders.
A Perl module for doing all the operation mixmaster clients and remailers need as well as an implementation of an actual client and a remailer.

I'm currently waiting for the people over at savannah to tell me whether they can provide CVS for software implementing or using crypto.
My CA-Bot is a collection of small scripts that help me do the paperwork which comes with doing GPG/PGP-Keysigning properly.
The code and everything is there, just not in a very releaseable status (It works for me and did so for the last year but it's not cleaned up). If you cannot wait for an official release, you'll find the tarball here.
Here be dragons
I started the #debian.de (on IRCnet and OPN) channel homepage. Even if many contributors do the main work - adding FAQ entries and fortunes - today, I'm still the one who autobuilds the page once a day.
The CVS can be viewed with ViewCVS or via anonymous cvs.
Libsis is a simple wrapper library which allows you to set the source address of outgoing TCP and UDP traffic.
Regular analysis on the Web of Trust within the Debian Keyring.
Code2HTML is a perl script that converts a program's source code to html to be displayed on a web site.
phpindent is a slow source code indenter for php which does not even work. More a proof of concept than anything else. It's just here because a friend said I wouldn't dare to publish it.
Over at www.noreply.org you can find some information about the rot26 remailer (an anonymous mixmaster remailer) and current stats from its pinger.
I maintain a few packages for the Debian GNU/Linux Distribution:
I'm also helping with Debian's Quality Assurance efforts (debcheck), sponsor prospective developers from time to time (check their packages, provide feedback and if everything is well done upload it into the archive), and do the Keyring Analyses regularily. I'm also getting involved with Software in the Public Interest, Inc., Debian's legal umbrella.
It is a small perl script I hacked together to make it simplier for the subscribers of one particular mailinglist to change their settings, subsccribe to the list, unsubscribe, get their forgotten passwords and so.
There are no admin functions (yet?) since I never needed them.
An anonymous pseudonym email server, such as that which runs nym.alias.net.
It lets you create an email address in an anonymous and secure fashion. You can then use this address to send and receive mail anonymously.
The next generation (type III) anonymous (emailing) network. Currently being designed, speficied, and implemented. Mixmaster 4.0 will also support Mixminion.
a small paper that descibes how hashing works (was only written to test code2html's inline feature).
A quick hack that updates ones dynamic dns entry over at dhs.org. Old, obsolete, probably doesn't work any longer.
Another quick hack which changes the output of ls, to make it display filesizes more readable. Probably doesn't apply against latest fileutils/coreutils.
Some stuff regarding my studies. Be warned that some/most of this is in German.
There's a short introduction into Digital Cash which I wrote for Hauptseminar Kryptographische Verfahren. [dir]
A paper I wrote with two friends (Wolfgang Klier and Bernhard Stader) for Proseminar Einführung in die Bioinformatik: Growing Artificial Neural Networks. [dir] (English).
For the Praktikum Automatische Verifikation reaktiver Systeme we developed a simple Model Checker. Its source can be found on my cvsweb: http://cvs.noreply.org/cgi-bin/viewcvs.cgi/avrs/?cvsroot=Praktikum+Automatische+Verifikation+Reaktiver+Systeme. With the release of bison 1.5, bison's parser is a lot stricter than it used to be, so it might not build any more. If you're interested in getting it to work just drop me a line - fixing is probably not very hard or time consuming.
In Praktikum Augmented Reality we played with real time 3D tracking, visualisation, and other fun stuff. For a overview visit the Praktikum's homepage, for a more detailed view on what my group did check out http://wwwbruegge.in.tum.de/projects/fixit/visualization/. (English).
