An easy to use program to find regular expressions in tripcodes such as those used on the popular 4chan imageboard.

• Regular expressions are converted into one RunAutomaton.
• (More or less) random password strings are generated.
• The tripcode of a given string is calculated.
• The RunAutomaton determines whether there is a match.
• The GUI displays matches.

• CUDA.
• Optimizing the DES crypt algorithm. It is dreadfully slow.
• Solving the issue of different threads calculating the same tripcodes.
• Adding support for auto-saving to file.
• Writing explanation of regular expressions - possibly in a new tab.

You'll want to use ant. Doing so, everything is very simple:

• ant compile compiles the project.
• ant test lanches the GUI.
• ant jar creates everything you need for a stand-alone run in the dist dir.
• ant zip creates housefire.zip in the root, containing the dist dir.
