Excel VBA工程密码破解

只看楼主收藏回复

如果要查看别人的有密码保护的VBA代码,可使用此程序。使用方法:新建Excel工作簿, 打开VBA编辑器,新建一模块 ,复制以下代码。然后运行MoveProtect程序。运行过程中会出现提示,以指示要破解的文件路径和名称。被破解的文件一定是关闭状态的。
Sub MoveProtect()
Dim FileName As String
FileName = Application.GetOpenFilename_
("Excel文件(*.xls & *.xla),*.xls;*.xla", , "VBA破解")
If FileName = CStr(False) Then
Exit Sub
Else
VBAPassword FileName, False ' 引用下面的自定义函数
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 "请先对VBA编码设置一个保护密码...", 32, "提示"
Exit Function
End If If Protect = False Then
Dim St As String * 2
Dim s20 As String * 1 '取得一个0D0A十六进制字串
Get #1, CMGs - 2, St '取得一个20十六制字串
Get #1, DPBo + 16, s20 '替换加密部份机码
For i = CMGs To DPBo Step 2
Put #1, i, St
Next '加入不配对符号
If (DPBo - CMGs) Mod 2 <> 0 Then
Put #1, DPBo + 1, s20
End If
MsgBox "文件解密成功......", 32, "提示"
Else
Dim MMs As String * 5
MMs = "DPB="""
Put #1, CMGs, MMs
MsgBox "对文件特殊加密成功......", 32, "提示"
End If
Close #1
End Function
所谓破解只是清除VBA密码,并不是真正的破解。
