After not being in this scene for a while, I decided to whip up a little crackme. I wrote this application in .NET35 so you will need that framework to run it (http://www.microsoft.com/download/DybolicCrackMe_V1.zips/details.aspx?FamilyId=333325FD-AE52-4E35-B531-508D977D32A6&displaylang=en).

I have Obfuscated the code so you cannot see the details of what I am doing (that would be too easy) :). That being said I would like to see a keygen on this application, I doubt it would not be hard to crack (give it a shot if you really want, but you will not impress me :) ). Good luck!

18. Nov 2008		hello dybloic,
it is still (?) possible to open the .net application with Reflector to see the source code.

[Reflector is free - download at http://www.red-gate.com/products/reflector/ ]

have fun with this crackme

@Alsor: of course Reflector, Dis# and similar tools will work, just most of the function names are obfuscated using a commercial obfuscator..

18. Nov 2008		@kao .. thanks for the compliment, let me know if you have any questions. I can provide a few keys if necessary, however, if I do that then it will make patching really really easy (and not an acceptable solution)

20. Nov 2008		Good crackme!
But there is a simple bug:
public string generateNameString(string name)
{
if (name.Length > 3)
{

Instead of this name.Length > 4 was correct.
Otherwise it will make exception :)
