Recently, I am working on java card security study. The first test I would like to do is trying to load a modified CAP file into java card.
I modify one byte of the CAP file at will via WinHex. What make me strange is that my modified CAP file can still be uploaded and installed with its standard method. Why? It's not correct in my view. Could anyone clarify it for me?

I just change one byte at will. And I am not clear that which component I modified? How can I confirm that?
