I had a busy week so I decided to leave it for the weekend, if I only knew how easy it was back then

 

Thanks for the challenge...

Good job also on this.  I guess removing the nag was also no problem!

@Maxx0r can you share with us source code of keygen?

Why do you complicate your life with ridiculous rules? There is no difference to use the ripped cryptocode inside or outside of the keygenme. It's like ripping whole the programm into my keygen. Goals are achieved. as I said the ways used for, does not matter.

 

What you said does not apply to this keygenme. Show me where the real serial is stored

 

No, no no no no no.

 

it DOES matter how you do stuff. You are meant to learn something from doing keygenmes. Not just doing stuff for the sake of stuff.

Oh, come on guys, be nice to each other!

Since 95% of code is ripped from crackme, it will look really ugly in IDA/Olly. Sorry about that.

njkermk did the almost the same thing, just didn't waste his time and energy copy-pasting code from original EXE to his keygen template. Is his work somehow less valuable?

In that case, only ChOoKi has made a proper keygen - by understanding the entire algorithm and reimplementing it in the most efficient way.

If i recall correct you say that a code ripping is a job that even a trained monkey can do. So why bother?

The "real" keygen is the solution IMHO. Food for the brain.

Sorry for little adding.

Yes, I still think that ripping code is a task for trained monkey. So, I was disappointed about how MaxX0r implemented the serial check..

 

However, in this case, one had to apply lots of patches to the original code, as it was generating only one correct symbol at a time, checking for "-", etc. Therefore, I still think njkermk deserves some appreciation for his ingenuity.

Sure.

Great RESPECT to all who solved this keygenme.
