Hey guys,

I've created a driver that injects my dll's into target applications. I however, want to protect my driver so that only I can use it. In order to ensure my driver isn't loaded and exploited by other people I want to make my driver read a signature file before injecting the dll to ensure that the signature file has been generated by my certification application and that the signature file has a matching signature with the signature found with the driver through the DLL that will be injected.

That way, even if other people took their own dll's and renamed them to match mine, it still won't work because the second signature would not match as the second signature is a unique signature separating all files.

However, I don't know where to start for the second signature. Is there a unique signature that labels every file? Where can I find it?

Thank you

Check http://code.google.com/p/cheat-engine/source/browse/trunk/DBKKernel/sigcheck.c

It checks with the public key if the signature provided in the .sig file has been signed with my private key and matches the accompanying file's signature that you generate at runtime
