zKnow is a simple home made cipher like algorithm that was designed to be used in a  zero knowledge proof. I originally created it as a learning experience and later experimented with using it as a way to authenticate some hardware for a company that I have worked for. There has not been much research into how secure the algorithm is, being that it is only 32 bits long it would be very simple to brute force. However it can be used in simple situations described below:
