We have a project where we are communicating with a "Black Box". Before we can communicate with it, the Box sends us a 2-byte token to which we have to respond. The response we send is based on the token the Box sends us. We don't know what the algorithm is thatís used to generate the response.

The task is to reverse engineering the algorithm used to generate the response. We have 4 examples of data the Black Box sends and the response it expects (see below). We have a fifth example we'll use to validate your algorithm.

We can pay $500 to have this algorithm reverse engineered.
