Excel 2013及更高版本中使用VBA的受保护工作表的密码破解程序

Question

有人知道是否有其他方法可以破解excel中受保护工作表的密码？从那以后我一直在使用这些代码,但现在它似乎不再起作用了.每次运行代码时,文件都会显示"Not Responding".我正在使用MS Office 2013.

Sub PasswordBreaker()
'Breaks worksheet password protection.
Dim i As Integer, j As Integer, k As Integer
Dim l As Integer, m As Integer, n As Integer
Dim i1 As Integer, i2 As Integer, i3 As Integer
Dim i4 As Integer, i5 As Integer, i6 As Integer
On Error Resume Next
For i = 65 To 66: For j = 65 To 66: For k = 65 To 66
For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66
For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66
For i5 = 65 To 66: For i6 = 65 To 66: For n = 32 To 126
ActiveSheet.Unprotect Chr(i) & Chr(j) & Chr(k) & _
    Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & _
    Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
If ActiveSheet.ProtectContents = False Then
    MsgBox "One usable password is " & Chr(i) & Chr(j) & _
        Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _
        Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
     Exit Sub
End If
Next: Next: Next: Next: Next: Next

Answer 1

Excel已在Excel 2013及更新版本中更新了其表单保护安全性,因此此宏将不再起作用,请参见此处.

从链接听起来如果您将文件保存为xls文件(Excel 1997-2003),它被迫删除较新的安全性,因为它与文件类型不兼容.然后,您可以运行您的宏.

保存为较旧的文件版本可能会使工作簿的某些部分无法正常工作.

谢谢 Kawi，它完美地工作。

这是 Kawi 修改后的完整代码：
