@Andu : You made me very curious ! So many questions about a way to protect your precious code, What are you developing ?
Is it a really very secret code or very expensive algos that you are trying to protect ?
So many commercial targets were cracked and also will be cracked, and I don't think that however any one tries ! If It's worth it then someone will crack it and that's what many years of reversing proved.
You can ask whatever you want here
I'm just curious !
