| obnoxious 26. Apr 2009 | huh so thers no goodboy msg just a serial length check ????? |
| Peroxaide 27. Apr 2009 | I don't think we understand what we're supposed to do -- By the looks of it, you input a userID, it outputs a PassID; You press the return key and the program exits. There's no distinctive place to input a serial. This is what's confusing us. |
| j2innet Author 29. Apr 2009 | oh, i think u are right. i will recompile a new one with key generated and let user to key in. |
| j2innet Author 06. May 2009 | hi obnoxious/peroxaide, this version require u to key in the right passid. |

| j2innet Author 12. May 2009 | someone found the mechanism of this crackme. his name is indivisible_int. he hasn't post any comment in this thread. my conversation with him-> "yah. you found it. the (password length)==(input length) the password is filled from series of state machines. each character password is filled by one state machine." most cases, the goodboy key is always one line of code. to find the goodboy key generator is the challenge. |
