It looks like I may have to implement something similar. Not trivial, and obviously hackable, but better than nothing. I'm fairly sure this patent is referring to Apple's method of encrypting certain binaries (Finder, Dock, etc.) which can "only" (I think it's been cracked now?) be decrypted with the "Dont Steal Mac OS X.kext" kernel extension (check out your /System/ Library/Extensions folder). A very nice article on the subject can be found here: http:// www.osxbook.com/book/bonus/chapter7/binaryprotection/ This may be slightly off topic, but does anyone know of any object code obfuscators which will work with mach-o binaries (PPC and x86)? I've looked around but haven't had much luck. The only product even remotely related I've been able to find is a C/C++ source code obfuscator from stunnix (http://stunnix.com/prod/cxxo/ overview.shtml), which I assume won't much good in terms obfuscating the generated object code. Apparently Apple applied for a patent a couple years ago on some object code obfuscation technology (http://www.macsimumnews.com/ index.php/archive/ apple_files_patent_system_and_method_for_creating_tamper_resistant_co de/). But if they've done anything with it, they haven't made it public. Other than the somewhat irrelevant product from stunnix above, I haven't been able to find any other third party commercial or open source technologies.
