Anti-Spam SMTP Proxy Server implements multiple spam filters
The Anti-Spam SMTP Proxy (ASSP) Server project aims to create an open source platform-independent SMTP Proxy server which implements auto-whitelists, self learning Hidden-Markov-Model and/or Bayesian, Greylisting, DNSBL, DNSWL, URIBL, SPF, SRS, Backscatter, Virus scanning, attachment blocking, Senderbase and multiple other filter methods. Click 'Files' to download the professional version 2.6.1 build 17355. An linux and a freeBSD based OVA of ASSP V2 are also available for download. NOTICE: V1 development has been stopped at the end of 2014 (1.10.1 build 16060). Possibly there will be done some bugfixing in future. Please upgrade to V2, which is and will be actively maintained.
System for anonymous Web browsing
Our goal is to develop, implement, evaluate and provide a secure and scaleable technical infrastructure for anonymous communication. This project is supported by Deutsche Forschungsgemeinschaft (DFG).
No-Name Instant Messenger is a secure (strong cryptography), cross platform communications program that supports existing IM networks (AIM, Yahoo, ICQ, etc.).
siggen is a cool email signature generator for encrypted ansi c (confused), brainf*ck, ... signatures. Use it in combination with vi(m), emacs, mutt, pine, or what ever. (tested on Solaris, Linux and Windoze). Optimized only for geeks :-)
The purpose of wxSSL is to allow wxWindows programmers to write SSL programs using socket classes similar to what exists in the current wxWindows. wxSSL will implement the IPC and socket classes over SSL.
password safe / manager for linux and windows (and mac ?) via qt
Password safe for Windows and Linux. If you want to manage your passwords (or other information) in one file and access that file with Windows and with Linux, this could be your choice. You create trees where each knot and leaf contains as many key/value pairs as you like. Then the whole thing is written encrypted to one file. Windows binaries and Debian32/64 binaries are downloadable. If you want to build it yourself - I suggest Linux users do that - get Qt4, call qmake and make in the directory where the .pro file is and you should be done. When building with Windows I suggest MinGw. The encryption is taken from a c-sample from Bruce Schneiers site. If someone could check it, that would be nice.
