What is the best software protection?

to ARC: Its possible create keygen for Armadillo without valid license key or without run of application.

to gorge: Hehe. "Code-Lock has never been cracked", I think its really bullshit. Maybe thier example for competition. But I can create something like this with ASProtect, PELock or SVKP too. I will use RSA encrypted blocks and I will never release license key for it. Then try to crack it. Its not possible, maybe for Armadillo
