| HMX0101 15. May 2008 | Lol, this is a joke? :P I don't think its a level 3, probably a level 2 or 1 ;) This is easy even for me, which i'm a .NET noob :P |
|---|---|
| SubmiN|KinG Author 15. May 2008 | maybe easy for u bro, but what about the dedicated .NET freaks who has no clue about x86 in general? :P |
| obnoxious 17. May 2008 | Mach 4 plz make a video soln for this 1. N yeah looking forward to HMX0101 's soln. I cdnt make any sense of the code in reflector. :-( |
| Zaphod 19. May 2008 | I know very little about .NET, but I do think I understand the functions shown in Reflector. That does not help me to solve the crackme, however. Olly isn't much help here. I can break several places in ADVAPI or rsaEnh or mcorwks, but that doesn't get me anywhere. I hope someone writes a solution. What do you say, HMX0101? |
| costy 19. May 2008 | the problem is emulating the GetHashCode with another language. How do it in c++?? |
| costy 20. May 2008 | crackme uses GetHashCode. So keygen should use GetHashCode but I have not Visual Studio so I can not write a .Net application. How can I write a keygen emulating GetHashCode with another language?? |
| MACH4 20. May 2008 | I'm not sure that you can unless you can locate the hash algorithm somewhere! I don't think its very complicated, just needs to be found if you want to use it in another language. could be making things difficult for yourself though because GetHash & GetHashCode usually involves a few other cryptos in most Crackmes of that type. |
| costy 21. May 2008 | okok I'm downloading Visual Studio Trial from Microsoft Site |
| SubmiN|KinG Author 31. May 2008 | no solution yet? it cant be that hard.... |
| TiGa 31. May 2008 | MSDN has many examples on how to use GetHashCode in other languages than the .NET Framework. |
| Jim~ 31. May 2008 | costy, open up relfector and use it to analyze mscorlib->System.String.GetHashCode ;) |
| MulleDK13 01. Jun 2008 | I think it's quite easy, but damn there is a lot of functions, that needs to be analyzed -.- |
| costy 12. Jul 2008 | Could someone explain something about this crackme?? All is unreadable. |
| costy 12. Jul 2008 | I want to mean how is it possible to understand something like these lines: Dim ░2 As ░3 = ░3.op_RightShift(k, shiftVal) Return ░3.▄38(P, Q, ░2, n, constant, shiftVal) Strange net application. |
| MACH4 12. Jul 2008 | Those weird symbols have replaced the original plain names. its for making the code harder to read and also will crash VS if you try to copy & paste them. Have a look at one of my previous tutes, it shows a manual way to sort them out into understandable names. If these function hieroglyphics grow much more it will be worth considering dumping into a file a run some scripts on it (find and replace). Beware some names especially in function definitions might have to be changed back to original names to work. BTW. when I see GetHashCode in crackmes I'm always a bit cautious because the outcome is not guaranteed to be unique, at least not in a double, string or arrays... |
| costy 14. Jul 2008 | I read them. T he dump fuction of net reflector doesnt work really well. Infact if i dump a normal application it gives me a lot of problems. I usually copy and paste code manually. If it gives me problems with standard application... It surely dont work on this one. I hope someone send a solution explaining how does he solved it and what tool he used. I hope the author will give some helps. Bye. |
| MACH4 14. Jul 2008 | Their from the unicode character set, VS don't like unicode and reflector gets a bit sticky with it sometimes but you can copy and paste it after a few attempts. might be easier to dump it into notepad with the unicode option on, it will preserve the characters |
| costy 15. Jul 2008 | Really interesting. MACH4 your informations are really interesting. |
