mrexodia Posted December 15, 2011 Share Posted December 15, 2011 Hello everyone, I had some time and in that time I decided to write a small KeygenMe challenge... You need to find a name/serial combination (multiple serials for one name are possible) and it would be nice if you create a small tutorial and not say: "this is weak because: [list of weak places]" this is not really nice for the users who are still trying to solve it Don't expect many special things, the only real protection is the (lame) anti-referenced text strings feature. Solutions (with tutorial) can be send to mr.exodia.tpodt@gmail.com/by pm and will be placed on my website.. Download here (failed to attach) Greetings, Mr. eXoDia PS Forgive me for the GFX, art not my best subject 1 Link to comment Share on other sites More sharing options...

Congratulations! Now could you please tell me which level (1-10) you would rate this... Greetings, Mr. eXoDia Link to comment Share on other sites More sharing options...
ChOoKi Posted December 18, 2011 Share Posted December 18, 2011 Based on my findings Difficulty : 3/10 (simple yet cheeky, what you find in today's softwares) Implementation/Code : 6/10 +6 : mixed order of checks -2 : bug/feature (you decide) @ 0040154C MOVSX EDX,DL -1 : name box length changing to suite display despite algo shows 40 chrs (10 xors) -1 : GetDlgItem grabbing 39 of 40 name chrs GFX : 5/10 SFX : 5/10 I must admit I enjoyed it though, a good exercise especially when coding a keygen for it, so many ways, hard to choose Link to comment Share on other sites More sharing options...

mrexodia Posted December 21, 2011 Author Share Posted December 21, 2011 (edited) The original idea is based on a 4x4 sudoku with a 2x2 field in the middle... I have to say the name checksum thing is kinda badly implemented... At first I wanted to do some 2.000.000 round sha+md5 hash which would be the checksum (just like in armadillo) but solving such an algo takes waays to long and therefore I decided to leave that @Chooki: Thanks for the tut, I'll put it on my website if you don't mind... And you can have the sources if you bother looking at my crappy coded c code @Mixuss: Your patch isn't working properly... @BeBoss: Keep trying, you'll solve it some day..

ChOoKi Posted April 29, 2014 Share Posted April 29, 2014 A new step-by-step presentation on how to solve this challenge, hope someone finds it useful. p.s: For further info, please refer to the tutorial posted earlier (above) . @eXoDia: Still waiting here for the name of the software Sol2014.7z 2 Link to comment Share on other sites More sharing options...
mrexodia Posted April 29, 2014 Author Share Posted April 29, 2014 @ChOoKi: I designed the algorithm 100% by myself, so there is no software linked to it. If I recall correctly I found inspiration on a 4x4 sudoku Greetings 1 Link to comment Share on other sites More sharing options...
