Real VNC Auth-Method Vuln Test Client  (free)
The Real-VNC client compiled to select NO_AUTH as it's primary method of authentication.  Real-VNC versions prior to Jun 2006 are likely to suffer from this particular flaw.  Some of our workstations had this issue and we were able to diagnose it using this program.  DO NOT USE THIS PROGRAM TO TEST ANY SYSTEMS BUT YOUR OWN!!!!  

OverClocker Source / Overclocker EXE  (free)
Overclocker will set the time in Windows to some date in the distant future and attempt a reboot, then it will try to load a web page to test firewall stability.  1 year ago this program would allow you to send email into the future (since fixed in outlook) and kill 6 different anti-virus programs as well as two of the best personal firewalls.  Now it still will crash some things.  Let me know if you do anything cool with it.
 
Clockwatch is a program that will catch clock problems and fix the system clock before your system has a chance to crash from over-clocking.  DO NOT USE THIS PROGRAM TO TEST ANY SYSTEMS BUT YOUR OWN!!!!

Puzzler Chess Puzzle Player (Freeware alpha - in progress)
A chess program that allows you to play, create and experiment with chess puzzles.  I ported this to a new version of Delphi and now it has an occasional exception in it as well as some hard to diagnose bugs.  I'll be working on it more soon but for now I'm giving it away if you feel like putting up with the strangeness that sometimes happens. Come back in a month or two and I should have a major fix for it.

1000 Words Steganographic Encryption  ($495)
Encrypt files of any type inside of a photo or graphic image.  Ex: you can put a zip file inside of a picture, picture inside of a picture inside of a picture... you get the idea!   The file is Twofish encrypted and then hidden inside of a picture.   You can also store a text message in the picture and the reader is not allowed to cut or copy the text out.  A shared secret key is the only way to unlock the data inside.  A typical method would be the words from a specific book on a specific page that matches the date of the file.

The picture is viewable in any standard image program and there is no way to tell if there is data inside unless you know the exact password and also happen to have a copy of this very program. If the photo is re-saved in a paint program or edited it will no longer contain the data thereby increasing plausible deniability.

This is probably the strongest encryption available anywhere so due to export rules etc. if you want a copy please contact us.
