VBS 加解密 For MS Script Encode

這篇文章主要介紹了微軟自己的代碼加解密實現方法，需要的朋友可以參考下  

一、加密

復制代碼 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

復制代碼 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
        NomFichier=BrowseForFolder("Choose an encoded file", &H4031, &H0011)
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

If NomFichier<>"" Then
        Dim fso
        Set fso=WScript.CreateObject("Scripting.FileSystemObject")
        If fso.FileExists(NomFichier) Then
                Dim fic,contenu
                Set fic = fso.OpenTextFile(NomFichier, 1)
                Contenu=fic.readAll
                fic.close
                Set fic=Nothing
                Const TagInit="#@~^" '#@~^awQAAA==
                Const TagFin="==^#~@" '& chr(0)
                Dim DebutCode, FinCode
                Do
     FinCode=0
     DebutCode=Instr(Contenu,TagInit)
     If DebutCode>0 Then
      If (Instr(DebutCode,Contenu,"==")-DebutCode)=10 Then 'If "==" follows the tag
       FinCode=Instr(DebutCode,Contenu,TagFin)
       If FinCode>0 Then
        Contenu=Left(Contenu,DebutCode-1) & _
        Decode(Mid(Contenu,DebutCode+12,FinCode-DebutCode-12-6)) & _
        Mid(Contenu,FinCode+6)
       End If
      End If
     End If
                Loop Until FinCode=0
                WScript.Echo Contenu
        Else
                WScript.Echo Nomfichier & " not found"
        End If
        Set fso=Nothing

Else
        WScript.Echo "Please give a filename"
        WScript.Echo "Usage : " & wscript.fullname  & " " & WScript.ScriptFullName & " <filename>"

End If
 

Function Decode(Chaine)
        Dim se,i,c,j,index,ChaineTemp
        Dim tDecode(127)
        Const Combinaison="1231232332321323132311233213233211323231311231321323112331123132"
        Set se=WSCript.CreateObject("Scripting.Encoder")
        For i=9 to 127
                tDecode(i)="JLA"
        Next

        For i=9 to 127
                ChaineTemp=Mid(se.EncodeScriptFile(".vbs",string(3,i),0,""),13,3)
                For j=1 to 3
                        c=Asc(Mid(ChaineTemp,j,1))
                        tDecode(c)=Left(tDecode(c),j-1) & chr(i) & Mid(tDecode(c),j+1)
                Next
        Next

        'Next line we correct a bug, otherwise a ")" could be decoded to a ">"
        tDecode(42)=Left(tDecode(42),1) & ")" & Right(tDecode(42),1)
        Set se=Nothing
        Chaine=Replace(Replace(Chaine,"@&",chr(10)),"@#",chr(13))
        Chaine=Replace(Replace(Chaine,"@*",">"),"@!","<")
        Chaine=Replace(Chaine,"@$","@")
        index=-1
        For i=1 to Len(Chaine)
                c=asc(Mid(Chaine,i,1))
