That's exactly what I believe.
I'm still quite stunned about the amount of work you put in anti piracy measures. :o Would be a good idea to think about making it available for others too, as i can't imagine every developer being able and willing to put so much effort in it.
My passion to talk about it is much larger than the effort actually spent on coding things.

Back then, when Team AiR douched out with their premature Zebra keygen, I made the decision to make this a hobby of mine. Nevertheless, I deal with CP for a day or two whenever a crack comes out, no more no less. However, there's a bit of a thinktank around, and we came up with many concepts that I haven't even implemented yet, simply because there wasn't any necessity to do so.

But yes, sharing those concepts with other developers - not just on forum-post level, but with detailed description - would be the next level of the protection scheme itself.

The author of IDA already explained it in quite some detail. You can find a lot of information about the halting problem described by Alan Turing in the 1930s.

TLDR; If they were to implement one method of identifying code it is absolutely certain to have false positives. If they implement a solution for the false positives it will no longer identify some of the previously identified code. Et cetera.

It can be reduced to the halting problem, which we have a proof is unsolvable since Alan Turing published it.

I'm working in AI research (and development) so I'm aware of what it is and who came up with it (Turing is one of my heroes for obvious reasons). I've read his papers, and also read most of the significant papers opposing his ideas (and many agreeing to his ideas).

I asked, because throwing in something like the halting problem into this discussion seems pretty irrelevant to it. The halting problem itself has been deemed irrelevant in many computational areas (although this can be, and is widely, debated), especially as we are now moving into the design of 'complex systems' (also known as 'bizarre' systems), where the question of predictability is totally irrelevant to begin with.

As a side note, and within the scope of this topic, a 'complex system' could actually create a uncrackable system, simply because it's state (at any moment) can not be mathematically predicted ;)

You seem to like to flaunt your knowledge, but posting things like this just makes you look like a know-it-all. Now, if you had mentioned 'P versus NP' in relation to CP, that would have been somewhat relevant (but still probably way out of the comfort zone for most participants in this discussion).

So what would be the point? It is related to the halting problem, it is the very same problem. Saying anything else would be really "flaunting knowledge" as it would serve no other purpose.

Looking up "what the heck is the halting problem?" will take anyone five minutes of reading and they'll understand why it is impossible to reliably detect stub functions.

The missing bit of info is exactly how IDA detects functions, which is proprietary. I do know however that it relies heavily upon alignment, stack push/pop and return opcodes, which stub functions do not contain.

I cannot believe you guys have been arguing about this for 20 pages when in the same edition is an inteview with Ulrich Schnauss, and his absolute droolworthy collection of gear. :love:

Well, the idea that a thread like this is kept alive be continued regular high profile 'offenses' is just ridiculous.

Can't find it on YouTube though :(

You seem to underestimate the knowledge & power of some reverse engineers out there! :hihi: You can study some of their clips even on YouTube. Be sure, if one of those extraordinary skilled men decides to crack your stuff you can't do nothing against it except implementing new protections in the next builds.

One thing that might save you from direct attacks is: You're a small developer. So they might feel sorry for you and let you go. It's like in nature: the big sharks come when they detect a big prey!

All hail the crackers and their omnipotent and infinite skill, mercy and grace! :hihi:
