| TQN 10. Jul 2006 | I think this crackme have a bug. ECX was changed after the call GetWindowTextLengthA at 00401106. So the value of ECX will be a random value after the call, and the hash function at 004012CA will return a random value of ECX too. Regards, |

| zairon Moderator 10. Jul 2006 | A new version of the file has been updated. Problem should be fixed now. |
| m@rio_crk 10. Jul 2006 | Is this a bug?: .text:0040118B push offset dword_40321C .text:00401190 push offset dword_403218 .text:00401195 call sub_401278 Inside this call: .text:0040127F mov eax, [ebp+arg_0] .text:00401282 mov ebx, [ebp+arg_4] eax and ebx holds the offset value, not the 'hash' value, so the serial depends not on the name but on the offsets. I think it's a bug.. I hope you think that too ;) |
| Ox87k 10. Jul 2006 | Here is my kgn in C (only exe obviosly) Works fine on my machine, h*tp://rapidshare.de/files/25487085/kgn.zip.html Sorry but i'm too lazy to write a solution :P btw good j0b Kostya, i hope to see another keygenme, more hard than this ;) ! |
| TQN 11. Jul 2006 | Sorry Kostya, but your crackme crashed on my Win2000. The EBX register was changed in DlgProc. We need push EBX on the stack before we can use it. We should not modify EBX, ESI, EDI register. Regards, |
| Kostya Author 11. Jul 2006 | Oh, Damn! Misprints... no need in offset values in this func... :(.. .. Ox87k, Thanx for keygen... :) to TQN: It was my first keygenme. I'll try to fix these problems in my second crackme. Thanks again! |
