You should try Dede and look for used units, there are only few implementations of RC5 on net. I dont'n know what you're trying to crack but I'd bet that it will use DCPCrypt1/2(hxxp://www.cityinthesky.co.uk/). Load it into Delphi, make sample app, debug in Delphi internal debugger and learn.

Thanks for nonambiguous comments, I am using DeDe which is a great tool and has helped me a lot in understanding how the program works, though I still have much to learn.

I was hoping that it uses a standard library suchs as DCPCrypt, it uses something called TCipherStreamFactoryRC5 to handle the decryption.

Web searches have proved fruitless, so I can only guess it is a custom lib. Anyone heard of this ?
