True, but even encryption is little more than security though obscurity if the keys are stored locally. Requesting a key to decrypt the code via some key exchange mechanism with a remote host is unfortunately not an option in the case I am looking at. The purpose here is really to make it just painful enough to discourage reverse engineering.

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. You should be aware that information theory dictates that all unencrypted, obfuscated object code can be deobfuscated via static analysis; this is probably not worth your time to pursue. -- Terry This email sent to site_archiver@lists.apple.com
