EXCEL密码破解

小子快跑

@@这是写保护的破解：


各位可以试一下：www.020outdoor.com

设置密码：

    打开excel文件： 工具-》保护-》设置密码

然后打开





方法:
1\打开文件
2\工具---宏----录制新宏---输入名字如:aa
3\停止录制(这样得到一个空宏)
4\工具---宏----宏,选aa,点编辑按钮，你会看到如下代码

Sub aa()
'
' aa Macro
' 宏由 X 录制，时间: 2009-7-18
'

'
    Application.Run "Book1.xls!aa"
    Application.Goto Reference:="aa"
End Sub

你要做的将中间那段替换成下面所示的附件sub PasswordBreaker() 和end sub得中间那段


　Dim i As Integer, j As Integer, k As Integer
　　Dim l As Integer, m As Integer, n As Integer
。。。

结果就像这样：
Sub aa()

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


6. 然后执行便可获得密码

　　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

今天解决的大问题！！

解释一下：


当Excel工作表采用密码保护时，就会生成一个16位(双字节)长hash值。当输入密码进行验证时，真正进行比较的就是这个hash值。事实上，有很多不同的密码都可以生成同样的hash值。

　　大家可以试试：

　　当你用“test”(不含双引号)作为Excel工作表保护密码，你同样可以用“zzyw”(同样不含双引号)这个密码进行解锁。怎么样，神奇吧?
