| HMX0101 13. Dec 2005 | for the serial calculation, look at offset 00401064 ;) |

| Eastern Dragon Author 13. Dec 2005 | I have to disappoint you, there is no serial calculation in this keygenme. Only a serial check. It is not possible to sniff a key or make a keygenerator by ripping code. |
| HMX0101 13. Dec 2005 | excuse me, for the inconvenient :) |
| kao 15. Dec 2005 | nice crackme! :) |
| jB_ 18. Dec 2005 | Very nice crackme, Eastern Dragon. I never saw such stuff in a crackme. I'll code a keygen very soon. |
| jB_ 18. Dec 2005 | Keygen ready, the code was not really time consuming :) The algorithm is fully reversed, contrary to the solution posted by gome (nice solution though). Only on my webpage ( http://jardinezchezjb.free.fr ), as I was too lazy to write a tutorial as usual :( I promise I'll do it soon, this keygenme is worth a few pages! |
| Eastern Dragon Author 19. Dec 2005 | @gome your solution works, but it is not beautiful. the keygenme was designed to be solvable without brute force, albeit probably not without reading Hint 3 (see About dialog). anyway, thanks for the time you took to reverse this thing and write the bruter and the tutorial. @jB thanks for your kind words. i really look up to you as a keygenner, you are one of the true masters of this art. your page with your crypto-keygens is an invaluable resource. greatly looking forward to your tutorial. |
