新建一個Excel工作簿,Alt+F11 開啟VBA編輯器,新建一個模組 ,複製以下程式碼,注意如提示變數未定義,則把Option Explicit行刪除即可,經測試已經透過.

'移除VBA編碼保護
Sub MoveProtect()
    Dim FileName As String
    FileName = Application.GetOpenFilename("Excel檔案(*.xls & *.xla),*.xls;*.xla", , "VBA破解")
    If FileName = CStr(False) Then
       Exit Sub
    Else
       VBAPassword FileName, False
    End If
End Sub

'設定VBA編碼保護
Sub SetProtect()
    Dim FileName As String
    FileName = Application.GetOpenFilename("Excel檔案(*.xls & *.xla),*.xls;*.xla", , "VBA破解")
    If FileName = CStr(False) Then
       Exit Sub
    Else
       VBAPassword FileName, True
    End If
End Sub

Private Function VBAPassword(FileName As String, Optional Protect As Boolean = False)
      If Dir(FileName) = "" Then
         Exit Function
      Else
         FileCopy FileName, FileName & ".bak"
      End If

      Dim GetData As String * 5
      Open FileName For Binary As #1
      Dim CMGs As Long
      Dim DPBo As Long
      For i = 1 To LOF(1)
          Get #1, i, GetData
          If GetData = "CMG=""" Then CMGs = i
          If GetData = "[Host" Then DPBo = i - 2: Exit For
      Next
      If CMGs = 0 Then
         MsgBox "請先對VBA編碼設定一個保護密碼...", 32, "提示"
         Exit Function
      End If
      If Protect = False Then
         Dim St As String * 2
         Dim s20 As String * 1
         '取得一個0D0A十六進位制字串
         Get #1, CMGs - 2, St
         '取得一個20十六制字串
         Get #1, DPBo + 16, s20
         '替換加密部份機碼
         For i = CMGs To DPBo Step 2
             Put #1, i, St
         Next
         '加入不配對符號
         If (DPBo - CMGs) Mod 2 <> 0 Then
            Put #1, DPBo + 1, s20
         End If
         MsgBox "檔案解密成功......", 32, "提示"
      Else
         Dim MMs As String * 5
         MMs = "DPB="""
         Put #1, CMGs, MMs
         MsgBox "對檔案特殊加密成功......", 32, "提示"
      End If
      Close #1
End Function
