Different files have different methods of implementing password protection. For ZIP you can find that information in the ZIP specification (Google should help you find that), for Office 2007 that might also be public, for Office 2003 you might be out of luck since I believe that is a proprietary format and I do not know of any APIs to work with those files.
Need information on a function I've posted? Chances are it's at the
MSDN.
