I'm writing some kind of exe obfuscator, and this exe is output result of obfuscating by
my program. It contains some trash instructions (very few) and code is "breaked" on small
parts, putted in random parts of exe and connected with jumps :)

Tasks:

- for newbies:
just remove trash and get source code for this exe
- for pro's:
write a program for automated deobfuscation of this exe

Difficulty: 3 - Getting harder
Platform: Windows
Language: Assembler

Sweet crackme! :)

However, due to your ugly usage of EBX register and jump to procedure, its almost impossible to write perfect "automagic" tool... I am trying nevertheless...

Can I get some more samples for testing? ;)
