Things that I'm working on.
Or was working on.
I wrote a tool to encrypt files in DOS. It's appropriately enough called PBP for Pretty Bad Privacy. Don't use it for anything else except as something that should be broken to learn how to reverse engineer basic encryption.
This is the simulator that I wrote for my final year undergrad project.
This is a secure VoIP implementation that uses AES and RSA to ensure data integrity. Currently, a Windows only version is available. The source and the binary are available on request.
This is a C++ based implementation of the Yarrow PRNG. This is a secure random number generator that can be used in a variety of systems. It derives it's randomness from using system specific information. Currently, a Linux only version is available, but very few plans are on to develop a Windows version of the same. :)
This is an implementation of a Genetic Algorithm Toolkit that allows a programmer to quickly code and test various genetic solutions to conventional problems. This code, while heavily relying on Unix utilities, should be cross platform portable.
