| indomit 09. Apr 2009 | Cool! New nice .net crackme! :) |
| indomit 09. Apr 2009 | I have found key for my name! Now thinking about keygen. As always it is the hardest part :) |
| indomit 09. Apr 2009 | 2obnoxious: In function_one() after num &= 15, there is no corrections for (num >=5) && (num <10). so if num == 7 we can't create 34 different parts... |
| indomit 09. Apr 2009 | also if function_one() returns "10", there is no correct keys, since in chk() function it compares with one char. P.S. sorry for spaming %) |
| obnoxious Author 09. Apr 2009 | :) gr8 that u like it. As always, i think it sd be tougher to write a keygen rather than finding a way to crack it. BTW does it exceed 0xF id = id & 0xf so max id can be 0xF as anything & 0xF will return at max F. correct me if i am wrong. sometimes i can be very stupid :D. |
| obnoxious Author 09. Apr 2009 | Off topic: Does any one kno scheme(programming language) if yes plz leave a comment. i need some help in scheme :( |
| indomit 10. Apr 2009 | ok. let's suppose after id = id & 0xf id == 0xf then if (id >= 10) id -= 5; id == 10 then in chk() function: if (Convert.ToChar(symbol).ToString() == id.ToString()) it compares one char "?" to string with two chars "10", and never be true. Next example: let id & 15 == 7 if (id >= 10) nope; if (id < 5) nope; function_one returns 7. function_two returns 34. But now with 7 we cant create 34 different parts of key. (only 21 for 7) Or I miss something? |
