| Ox87k 04. Jan 2006 | ollydump has some problem with iat and i don't understand what is this problem.. however importrec works! i unpack it, the 3 routine is very simple, so i hope to find some time for write a little tut+kgn! thanks for this crackme.. |
|---|---|
| HMX0101 04. Jan 2006 | i have ripped the code to make the keygen |
| HMX0101 04. Jan 2006 | i can't rip the code of 2nd serial generation, i'm trying the old method |
| Geminias 05. Jan 2006 | the tutorials i've read seem to launch right into the reversing. Can someone please explain step 1, as in, you get an executable crack me and nothing else. So you look at this box with a text field with a label beside it saying "enter password" what would be the first steps you would take? like don't you have to retrieve hashes from memory somewhere? or dont you have to brute it to see what kinds of serials it accepts? |
| KLiZMA Author 05. Jan 2006 | Lots of thanx: Ox87k and HMX0101 |
| Ank83 05. Jan 2006 | i'm writing a keygen as the first one this is very nice crackme. Not so hard algoritams. If you understand the first cracme - it's almoust imposible not to solved this one ! Thanks Klizma for giving us target to practice ! Best Regards Ank83 |
| Ox87k 05. Jan 2006 | self-keygenning is allowed?? :) |
| HMX0101 05. Jan 2006 | this is more easy than the first, i'm writing the keygen |
| Ank83 06. Jan 2006 | hi i need help ! what function is in c++ or vb the IMUL in asm ! I have problems with generating the third serial ! |
| m@[tador] 06. Jan 2006 | Ank83: IMUL is signed multiplication. Maybe in C++ and VB is '*' operation? |
| KLiZMA Author 06. Jan 2006 | Who can write the solution or keygen? Ha. |
| Ox87k 06. Jan 2006 | i submitted my solution yesterday... i wrote a tutorial and i made a selfkeygen.. i hope that the moderators approve my solution! :) |
| fangrenxing 28. Apr, 04:04 | 이것이 나의 대답이다. s_sn1 = 3 * v_id1 / 2 + 330333; s_sn2 = (s_sn1 / 3 + 263524) / 2; s_sn3 = (s_sn2 + v_id1 + s_sn1) / 11; |
