[keygenme] Crypto Keygenme2

[grizzmo]

Hi,

 

Another keygenme, therefore called keygenme2. This time with a bit of crypto.

 

Packed with : confuser.

 

Unpacked the keygenme shouldn't be too hard for the bit experienced keygenners.

 

Crypto, level 2.

 

Kept simple!

 

Here is the keygenme in winrar for you all:

    End If

    If Me.method_5("REFLECTOR") Then

    End If

    If Me.method_5("SimpleAssemblyExplorer") Then

    End If

    If Me.method_5("simpleassemblyexplorer") Then

        Delegate66.smethod_0(Me)

    End If

    If Me.method_5("SIMPLEASSEMBLYEXPLORER") Then

        Delegate66.smethod_0(Me)

    End If

    If Me.method_5("OllyDBG") Then

        Delegate66.smethod_0(Me)

    End If

    If Me.method_5("ollydbg") Then

        Delegate66.smethod_0(Me)

    End If

    If Me.method_5("OLLYDBG") Then

        Delegate66.smethod_0(Me)

    End If

End Sub

Well, if you look further you would see that not all these closes are actually closing.

I implented these and decided to see, when you f.e., read these and responded. Reflector and Simple Assembly Explorer won't close my keygenme, but I was too lazy to select these code and delete, but yes, OllyDBG makes my keygenme close.

Btw nexttime Olly closes.

 

Regards.

 

P.s. I am not little, don't get me wrong Michael!

Btw nice video tut.

Easy keygenning for everyone with the cleaned file by GIV.

 

Really simple algo. If you never keygenned crypto you should try this one.

I wrote a keygen which is attached along with the source and a fully "unconfused" version of the keygenme (decrypted resources, strings, delegates, no control-flow and no anti-debug) using my deobfuscator. Wasn't very hard, basically copied and pasted the code.

 @master131 ,

 

Very good, unpacked file runs ok and the serial generation is as supposed to do.

Your keygen has been accepted as a valid solution. 

 

Thanks for posting the keygen and the keygen source.

Greetz.

Sorry for delay.

To GIV,

 

Thanks, the keygen is tested and working.

The source for the keygen is ok.

 

For the .NET starters in short, for help:

 

1. C# source by master131 in post #7.

 

2. VB.NET source by GIV in post #9
