| Tenshi 21. Dec 2005 | this is crapp....how will u make an key gen if the key is time beased ???? first an "U" u take seconds for example "40" then u take last to chars of the date ( for example 19-12-2005 = "05") And then "Grand-Theft-Auto-Vice-Citybbidhan-ThE-Great" so u have U+Sec+Year+String = serial greets ps: i wil build an fischer if i could i would post it here.... |
|---|---|
| Tenshi 21. Dec 2005 | sorry the "U" is the first char of name + 1 exmpl. "T" -> "U", "3" -> "4" |
| konstAnt 22. Dec 2005 | Wow I also found that I'll also write a solution |
| EsKiMo 22. Dec 2005 | The crackme is quite interesting. Although the serial generation is easy to understand, creating the KeyGen is not so easy! Submitted a solution. |
| Tenshi 23. Dec 2005 | the only thing u can do is to "froze" the time when the keygen is started.when the keygen is closed the "real" time has to to be set. the problem is that the keygen must run to work ;-) |
| konstAnt 23. Dec 2005 | Yah that was my idea too but I didn't get favourable condition to write a tut due to college days |
| Tenshi 23. Dec 2005 | there is an other idea from me, combine an loader and an key gen....load the crackme and than alway let him think that the seconds are "00" and then the keygen should work to..... its easyest way i think ;-) maybe i will write an solution.... |
| EsKiMo 23. Dec 2005 | Or... you could generate the serial based in the current time. Write a loader that read the username typed in the crackme, compute the serial and set it back in the keygen textbox! You have to do this procedure for every second. This way you don't change anything in your OS neither in the crackme. I think the author was excepting something like this. That's the solution I submitted. |
| Tenshi 24. Dec 2005 | buts not that effektive like the first idea, its the fastest and best way in my mind, but u are right u could do..... greets |
| konstAnt 25. Dec 2005 | Another easy way is tell the user to click the button only when the clock rings the correct time :P :lol |
| HMX0101 25. Dec 2005 | other way, make a small app for click the button |
| microplant[mp] 26. Dec 2005 | ok, the serial was pretty easy to find, but the keygen took me a while ^^ well, its finally ready and sent as solution :) |
| Tenshi 26. Dec 2005 | nice solutions.....merry christmas ;-) |
| konstAnt 28. Dec 2005 | Merry Christmas???? Happy New Year ... :P :lol |
