CrackMe3 Hellsp@wn Solution

This tutorial doesn't want to describe the methods I used to reverse this crackme, but rather the questions born in the mind of novel reverser like me … . So, you will ask: "Why did you choose this crackme" The answer is simple: THE CHALLENGE! The name of Hellsp@wn (coauthor of the principal Ollydbg's hide plugin: Phantom) and a crackme of level 5, dated 2006 and not yet resolved, are the right mix to test my abilities; indeed, the possibility to discover a new anti debug technique is behind the corner so good lecture and, as always, sorry for my poor English.
