Extreme crackme for cracker

"I can see,that the 2015 year cracker generation will
measure their knowledge on YOUR protection DD"

Well, I think I got something from 2015.It's not Armadillo and the
algoritm is very week,but I want only to make your work harder.
And I want to recommend it to the cracker named guys...
Well,we will see, how can you handle it...

The goal is to get the correct serial and register it on my
page.I measure thru this registration,who can solve this mistery.
So I think with this,It's become a competition.

WORKS ONLY ON NT/2000/XP/ AND ABOVE!!!
The level of the crackme is 8/10.
I made it for crack it,so it's not too hard,but not too easy.

funny, is that x86-to-text algorithm home made or is there already an existing snippet to do that?

iirc one was named dissembler.

Nice crackme

I just have the time to have a very short look at it. What the hell the crackme is doing in the Entrypoint. I just get out of the crackme after tracing 6 instructions

Shellcode? Hmm...never heard of that one. Just found a bit of information and now I know a bit more of it. So, how Windows starts executing that crackme? Anyone familiar with Shellcodes are welcome

Regards.

shellcodes are something totally different, those are used when exploiting a buffer overflow and give the exploiter a shell. that's why they are called shellcode.
