Even I can detect where the key was stored in 2-3 minutes, or even less. All I have to do is to keep the original key then restore it every day. Imagine that a hacker will find much better and quicker 'solutions'. Storing a key is unsafe. This is why I choose sending an unlock key based on hardware. They hacked my application one year ago in the part where it acted as a trial and stored data in registry. Now I removed that part and it is still holding un-cracked since then. Anyway, I am proud that somebody cracked my application. It means it is important. :) ___ Do you know how the hackers decided to crack an application? They answer to requests or are they paid or what?
