一、加密

代碼如下:

Dim ObjectFSO

If (lcase(right(wscript.fullname,11))="wscript.exe") Then

WScript.Quit(0)

End If

If wscript.arguments.count<2 Then

Wscript.Echo "VBS Code Encoder v1.0 Powered by ENUN. http://www.enun.net/"

Wscript.Echo "Notes: dFileName Must be '*.vbe'!"

Wscript.Echo "Usage: cscript.exe //nologo sFileName dFileName"

Wscript.Echo " eg: cscript.exe //nologo test.vbs enc.vbe"

WScript.Quit(0)

End If

sFileName = Wscript.Arguments(0)

dFileName = Wscript.Arguments(1)

Set ObjectFSO = CreateObject("Scripting.FileSystemObject")

Set ReadData = ObjectFSO.OpenTextFile(sFileName, 1)

ObjectFSO.OpenTextFile(dFileName, 8, true).Write(Encoder(ReadData.Readall))

Function Encoder(data)

Encoder = CreateObject("Scripting.Encoder").EncodeScriptFile(".vbs", data, 0, "VBScript")

End Function

二、解密

代碼如下:

option explicit

Dim oArgs, NomFichier

'Optional argument : the encoded filename

NomFichier=""

Set oArgs = WScript.Arguments

Select Case oArgs.Count

Case 0 'No Arg, popup a dialog box to choose the file

Case 1

If Instr(oArgs(0),"?")=0 Then '-? ou /? => aide

NomFichier=oArgs(0)

End If

Case Else

WScript.Echo "Too many parameters"

End Select

Set oArgs = Nothing

Dim fso

Set fso=WScript.CreateObject("Scripting.FileSystemObject")
