| indomit 16. Apr 2009 | Can't fully understand this logic, but found the key! :) |
| kao 16. Apr 2009 | Due to some coding errors, there are 74449344 valid passwords. And it can be easily bruteforced. :( That's a shame because otherwise it could have been a damn nice crackme... |
| DoomsDay Author 16. Apr 2009 | I've uploaded a fixed version. Unless I missed something out, there should be no more exploits. |
| simonzack Moderator 17. Apr 2009 | I think it still can be easily bruteforced, but anyway I'll analyze the whole thing |
| simonzack Moderator 17. Apr 2009 | took 10 minutes of guessing to find it out x.x now need to analyze it |
| kao 17. Apr 2009 | @simonzack: when you write a tutorial, please tell us how you managed to guess the key in 10 minutes, I'm very curious.. ;) |
| DoomsDay Author 17. Apr 2009 | I will attempt to fix the fault caused by my algebra and misuse of my macros (A final version will be uploaded shortly). I'm deeply sorry for the inconvenience =\; I guess my calculations were wrong. |
