Class CatDecoder 

java.lang.Object

   +----CatDecoder
public class CatDecoder
extends Object
The "CatDecoder" class provides a means of decoding the :Cue:C.A.T. encrypted string read as though typed on the keyboard by the :Cue:C.A.T. barcode scanner.

These scanners (and their software) are provided "free" by Digital Convergence:.Com (initially through Radio Shack stores).  Each scanner has its own built-in serial number which it reports as part of each scan.  The output of the scanner is (slightly) encrypted using a modified MIME-style base64 pattern with either of 2 exclusive-OR masks (one for the special :Cue:C.A.T. "cues", another for all other bar codes).
