Re: [softwaredev-113] Detecting if a windows executable has been tampered with

Signing won't really offer any protection (and it is really easy to get around). It was only intended to show someone that the assembly came from you. Microsoft is pretty much obsoleting this in vnext and is not recommending / signing their assemblies. The best route is to obfuscate your assemblies with a tool like Red-Gate (highly recommended).

I'm looking at adding some kind of crack detection to my windows applications. For some reason I thought if I sign the .exe with SignTool, and then open up the exe in a hex editor and change some bytes around, that Windows wouldn't launch it, but that doesn't seem to be the case.

Is there some "standard" method of detecting if the binary has been tampered with, or is this something I'll need to implement myself? Otherwise, what's the point of the codesign step?
