Open Source Security Software

-- WARNING -- HiJackThis is an inactive project and it is not updated anymore. You may want to look at the existent unofficial forks though: https://github.com/dragokas/hijackthis/ -- HijackThis is a free utility that generates an in depth report of registry and file settings from your computer. HijackThis scan results make no separation between safe and unsafe settings , which gives you the ability to selectively remove items from your machine. In addition to scan and remove capabilities, HijackThis comes with several useful tools to manually remove malware from your computer. However, HijackThis does not make value based calls between what is considered good or bad. It is important to exercise caution and avoid making changes to your computer settings, unless you have expert knowledge. Source code is available SourceForge, under Code and also as a zip file under Files.

The Arcanum Editor is a small but powerful tool to encrypt and decrypt messages. The program also comes with it's own format CTXT. This format is based on XML and allows you to save texts with the Advanced Encryption Standard.

Cryptex is a fast and simple easy to use open source software for encryption and decryption of files and folders. The software has a proprietary format for password management. Cryptex use AES and TripleDES algorithms.

IMPORTANT -- This is an old project that is no longer supported and should not be relied upon for serious applications. If your looking for encryption software, I suggest OpenSSL or GnuPG which are better equipped.

SEPIA provides implementations for various types of Petri nets. Along Place/Transition-nets, it supports Petri nets with distinguishable token colors and defines coloured workflow nets, where coloured tokens are interpreted as data elements used during process execution. To support information flow analysis of processes, SEPIA defines so-called IF-Nets, tailored for security-oriented workflow modeling which enable users to assign security-levels (HIGH, LOW) to transitions, data elements and persons/agents participating in the process execution. SEPIA builds upon TOVAL (http://sourceforge.net/p/toval), JAGAL (http://sourceforge.net/p/jagal) and SEWOL (https://sourceforge.net/projects/jawl/). To use SEPIA, make sure these libraries are on the build path. SEPIA encloses the Multi Schema Validator (https://msv.java.net/) and isorelax (http://iso-relax.sourceforge.net/) The documentation can be found under http://doku.telematik.uni-freiburg.de/sepia.
