Hi,
What I was really looking for is a way to prevent
hacked copies of an app from circulating. I believe
there may be such versions available already, or
possibly an app that attacks any other apps that use
our licensing engine. (I can't prove it, though, so I
can't design around _a_ specific type of attack, as
yet.)
Plugin signing would be nice, too, but I was thinking
primarily of the main app and/or anything else. I was
hoping for a system-level service such that the user
could be prompted by the OS before running the app.
You know, "This application does not appear to match
its digitial signature. Continue?" or something along
those lines.
In my limited experience with code signing, the file
size, a CRC value, etc. are usually included with the
signature to prevent exactly the sort of thing I'm
trying to prevent.
Yes, I realize that to some extent, nearly every
system is hackable. I'm only looking for more stuff to
slow 'em down. ;)
Thanks!
