宏密码破解方法

VBA宏代码破解法： 第一步：打开该文件，先解除默认的“宏禁用”状态，方法是点击工具栏下的“选项”状态按钮，打开“MicrosoftOffice安全选项”窗口，选择其中的“启用此内容”，“确定”退出(图2)； 再切换到“视图”选项卡，点击“宏”→“录制宏”，出现“录制新宏”窗口，在“宏名”定义一个名称为：PasswordBreaker(图3)，点击“确定”退出； 第二步：再点击“宏”→“查看宏”，选择“宏名”下的“PasswordBreaker”并点击“编辑”，打开“MicrosoftVisualBasic”编辑器，用如下内容替换右侧窗口中的所有代码： Sub PasswordBreaker() 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) ActiveWorkbook.Sheets(1).Select Range("a1").FormulaR1C1 = 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 Next: Next: Next: Next: Next: Next End Sub 第三步：再点击“宏”→“查看宏”，选择“宏名”下的“PasswordBreaker”并点击“执行”，密码就现形了(图4)。 第四步：切换“审阅”选项卡，点击“撤消工作表保护”，然后输入密码即可解除锁定。
