tarequl.hassan Posted February 11, 2012 Share Posted February 11, 2012 "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.http://www.4shared.com/file/Hir0vWj_/Dioniso_s_Crackme.htmlGreetings.PeterPunk"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.Dioniso_s_Crackme.zip 1 Link to comment Share on other sites More sharing options...
Raham Posted February 11, 2012 Share Posted February 11, 2012 HiValid Serial:RahamZXZZ<XWZZ=YXZW>YWYZand Main XOR Key:0xd105bac0Kind R3g4rd5 Link to comment Share on other sites More sharing options...
tarequl.hassan Posted February 12, 2012 Author Share Posted February 12, 2012 Great Work Raham. Could you please write a tutorial? Link to comment Share on other sites More sharing options...

tarequl.hassan Posted February 13, 2012 Author Share Posted February 13, 2012 for my name "tarequl" the XOR key C0BA05D1 Now how to make a key? Link to comment Share on other sites More sharing options...
Raham Posted February 13, 2012 Share Posted February 13, 2012 hiHere 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 RegardsCRC BruteForce.zip 1 Link to comment Share on other sites More sharing options...

Solution DE! Posted February 15, 2012 Solution Share Posted February 15, 2012 (edited) 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.

tarequl.hassan Posted February 17, 2012 Author Share Posted February 17, 2012 Simply 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.
