| DigitalAcid 24. Jun 2008 | All you need, is some grey matter ;). |
|---|---|
| WinFan Author 24. Jun 2008 | It's quite simple, yes. |
| obnoxious 27. Jun 2008 | i aint good with delphi but as digital acid has pointed out all it requires is some grey matter......:) |
| WinFan Author 27. Jun 2008 | You don't have to be good at delphi for this one! ;) |
| costy 27. Jun 2008 | I founded the solution but i didn't understand the code i just tried a lot of times and ... my brain is on fire |
| WinFan Author 27. Jun 2008 | You have to explain how it works :) |
| costy 29. Jun 2008 | I haven't explained the solution becouse I need 2 brains to solve this |
| Zaphod 01. Jul 2008 | I found the solution, too - but unfortunately just by trial and error. I cannot follow the code :( |
| br0ken 09. Jul 2008 | I patched stage 1 and found a valid name/serial combination for stage 2. However, a keygen might prove difficult. Selfkeygen is valid? |
| TiGa 10. Jul 2008 | As it is written in the crackme's description: Your task is to find the password, which lets you see the "correct" message! In your solution you should describe how the program checks for the right password. A self-bruteforcer or self-keygen doesn't explain much. |
| costy 26. Jul 2008 | @moderators I don't understand the algo in the debugger but I understand perfectly how the program works. I made a program that decript the message in the same way. I can explain exactly how the message is generated and i fouded the valid key. But I cannot comment the code that i can see in olly. Is this a valid solution?? I don't understand the code but I understood the program by trial and error!! |
| TiGa 27. Jul 2008 | Do your best and I'll give it a fair look. |
| costy 27. Jul 2008 | I will try to understand a bit about the code. |
| DigitalAcid 27. Jul 2008 | I don't really see what the code is doing either, but i know for 85% how to get the valid serial. It's really easy actually. Little example: 1 + 4 = 5 So to find 1(the solution), you need to do 5 - 4. Maybe i said too much with this. |
| WinFan Author 28. Jul 2008 | Look at the strings in Olly. The first 4 letters of the password is the first part of an language used in the program. |
| WinFan Author 09. Aug 2009 | Wow, no solution for this one yet? Almost a year ago ... |
