[KeyGenMe] Dioniso's Crackme

[tarequl.hassan]

"Good gentlemen,

I created a small crackme to be entertained for a ratillo.

It is programmed in MASM32 and no tricks antidebugger.

The mission, as usual, is to create the keygen. As I think is very simple try it without a bruteforce program.

Greetings.

Without the permission of peter punk friend of (www.portalhacker.net) portalhacker forum i have posted this keygenme as i found it great in keygenning. I posted this here for educational purpose for those who want to learn.

A great thanks to friend PetePunk for his great keygenme.

Hi

Valid Serial:

Raham

ZXZZ<XWZZ=YXZW>YWYZ

and Main XOR Key:

0xd105bac0

Kind R3g4rd5

[tarequl.hassan]

Great Work Raham. Could you please write a tutorial?

[Levis]

I'm waiting for a nice tutorial too. This crackme is very exciting

[Raham]

Hi

Sorry Mates, Im Busy on other stuff, so i couldnt make a tut...

but for XOR key i coded a small brute force program...

Kind Regards

[tarequl.hassan]

could you please upload that program "but for XOR key i coded a small brute force program..."

[tarequl.hassan]

for my name "tarequl" the XOR key C0BA05D1 Now how to make a key?

[Raham]

hi

Here is the my Brute Force Program...(Optimized for 8 Thread Processor, Like Core i7)

well, im Noob on Keygenning...when i saw your Algorithm...(ReadByte from Key,OR lastStuff with this, then LastStuff*4 and...)

i felt its better to do just some Test by my hand...not writing some keygen or something similar...

CRC of Your User XOR Value(of Calced from Serial) should be Orginal Key that I Brute Forced....

so XOR Main Key with your own CRC, the Serial Value shoule be that....

so just play a bit with Serial to Reach your Serial.

Kind Regards

Thank you Raham. Could you please give an example?

I also made a bruteforcer...Its only running in only in 1 thread and not very optimised but it works

The source is included (Lazarus/FPC).

And i also made a small tutorial. Attached as PDF

Update :

I added a keygen to this post and an update on the tutorial. Its indeed possible to skip the bruteforce and calculate the serial immediate.

Simply Amazing DE! Amazing. I was trying it for almost a month and failed to understand. I could xor ed but could not find out a way. A salute to you DE! Thanks again.
