Discussion and comments
| Zaphod 12. Oct 2008 | I finally found a working serial for this very nice crackme, but I cannot make a keygen. If someone can, I would be very interested in seeing it. ( There must be more than one solution ). |

| JoKa 16. Oct 2008 | You're right, many solutions. I can make keygen, but it will use some exhaustive searching. I did it so. I take pre-defined strings for four last EditBox as arguments. Calculate string in first EditBox and AllCharXor as result. Then slightly change middle chars in pre-defined strings to get only typable (and uppercase if letter) characters in first string. Then change minor chars in pre-defined strings to get AllCharXor=1. |
| Zaphod 16. Oct 2008 | I'm impressed, JoKa - you are good and you are fast! Are you writing a tutorial? |
| JoKa 17. Oct 2008 | I've written keygen which does this, but this slightly changing is not easy to automate, so this keygen can give keygen not for all initial pre-defined strings (if keygen cannot find it loops doesn't exit). pre-defined strings are changed very strong in this keygen for example: Enter four 5-char strings for starting keygenning: crack crack crack crack <Z-)\BQ@BJBQ@BJBQ@@I@Q@BJ |
| JoKa 17. Oct 2008 | I've changed keygen source, now it works better. It gives serial for many pre-define strings sets and does not change pre-defined strings too strong. Enter four 5-char strings for starting keygenning: crack crack crack crack LI<8[CRACKCRACKCRBAJTRACK |
