CSS(Content Scrambling System) Stream Cipher .

I need the programs to encode Content Scrambling System used in commercial DVDs and some of the attacks on this stream ciher. I prefer to use Java but I can also think about other languages . ## Deliverables I also have some implementation code that is written in C++ , what you need is to make appropriate changes or write it in java. I can also provide with the algorithm and little bit more help.
