穷举破解EXCEL、WORD文档密码

摘要：本文讨论了如何使用VB编程，通过穷举法解除EXCEL文档和WORD文档的密码。并在破解过程中加入了中断，以方便用户随时中断破解过程。

关键字：穷举法、解密、EXCEL文档、WORD文档、密码

Excel和Word提供了多种限制访问用户文档，以免未经授权者的查看和更改。但在信息化的今天，用户方法需要记忆的密码太多，一旦密码丢失，用户将无法打开或访问该文档，给用户造成很大的损失。能否借助计机的高速运行，解开密码呢？通过尝试，笔者认为：在无法弄清Excel 和Word加密算法的情况下，利用算穷举法尝试解密文档，是解密唯一的选择。

1. 实现原理

本程序选用VB6.0编写，并充分利用了Office组件中的对象库，穷举尝试各种口令，达到解密文档的目的。

⑴巧用整数的取整及取余，产生密码字符串

Excel和Word文档密码可以是字母、数字、空格以及符号的任意组合，最长可达 15 个字符，且区分大小写。

本程序的破解过程利用一个两层循环，产生选定字符的排列组合（尝试密码），其中外层循环控制密码的位数，内层循环生成N位密码的所有排列组合。产生尝试密码的是：将一个N位字符串密码（password）方法作为一个“数值”，该“数值”每个位上的“数字”属于选定字符范围，且该“数值”与一个整数（X）一一对应，并满足以下条件： 0 ≤X ≤ArrayLenN-1（ArrayLen 是选定密码字符范围的总字符数，如：仅选定数字时，ArrayLen=10；仅选定数字和小写字母时，ArrayLen=10+26=36）；对X整除、取余N-1次，对每次的余数Y做以下操作：password = password

+ CharArray(Y) （注：CharArray是存放选定字符的一维数组），最后做以下操作：password = CharArray(X MOD ArrayLen) + password，产生的password 就是整数X对应的N位字符串。

⑵利用VB的错误处理功能，尝试口令破解

当运行程序尝试一个密码时（用该密码打开文档），若密码错误，则会产生运行错误。为此，必

须在尝试口令前，使用On Error 语句打开一个错误处理程序；由于本程序是尝试各种口令，当

一个口令错误时，直接尝试下一个口令即可，因此，应使用“On Error Resume Next”语句。

那么，如何得知找到口令了呢？ VB有一个内部错误对象Err，它的 Number 属性中的值是用来

确定发生错误的原因。在尝试一个口令后，检查Err.Number中的值，以确定该口令是否正确。

⑶破解过程中的中断

利用穷举法解密对系统资源的占用是十分惊人的，在解密的过程中CPU的利用率几乎是100%，

若不加入解密过程中的中断，机系统会处于一种假死机状态。为此，在破解过程的内循环中加入

了DoEvents函数。计算DoEvents函数提供了一种取消任务的简便方法，它将控制切换到操作环

境内核。只要此环境中的所有程应用序都有机会响应待处理事件，程序就又恢复控制。使用该函

数的优点是：不会使应用程序放弃焦点，且应用后台事件能够得到有效处理。

2. 具体实现过程

编程实现时，需要机器安装有VB应用程序及Microsoft Office组件。

⑴新建VB工程，并对其初始化

新建一个VB工程，取名Get_Password，将启动窗体命名为FrmMain。首先选择“工程”菜单中

的“引用”，在“引用”对话框中选择“Microsoft Excel10.0 Object Library”和“Microsoft Word10.0 Object Library”文档．

实用标准文案

（注意：如果安装的是Office2000或Office97，应该选择Excel对象库和Word对象库的9.0

版或8.0版）。其次在“工程”菜单中“部件”对话框中，选择添加“Microsoft Windows common controls -2.5(sp2)”和“Microsoft Common Dialog control 6.0”，以便在窗体设计中使用微

调控件和对话框控件。

⑵在FrmMain窗体上添加控件

在FrmMain窗体上，按照下图的位置添加表1中的控件，然后根据表1修改每个对象的属性。

表1：

序号控件名称控件属性及其属性值

1 Frame Name=Frame1，Caption=选择加密（*.DOC、*.XLS）文件

2 Frame Name=Frame2，Caption=选定密码字符范围：

3 Frame Name=Frame3，Caption=选择密码的长度：

4 ComboBow Name=Combo1

5 CommandButton Name=CmdBrowse，Caption=浏览

6 CommandButton Name=CmdStartCrack，Caption=开始破解

7 CommandButton Name=CmdQuit，Caption=退出系统

8 CheckBox Name=ChkDigital，Caption=数字(10)

9 CheckBox Name=ChkLowercase，Caption=小写字母(26)

10 CheckBox Name=ChkUppercase，Caption=大写字母(26)

11 CheckBox Name=ChkSpace，Caption=空格(1)

12 CheckBox Name=ChkBracket，Caption=括号(6)

13 CheckBox Name=ChkOthers，Caption=其他OEM字符(26)

14 TextBox Name=txtPasswordStartLong， Text=2

15 TextBox Name=txtPasswordEndLong，Text=2

16 TextBox Name=Text1

17 UpDown Name=UpDown1，BuddyProperty=Text，Wrap=TRUE，Increment=1

BuddyControl=txtPasswordStartLong，Max=15，Min=

18 UpDown Name=UpDown2，BuddyProperty=Text，Wrap=TRUE，Increment=1

BuddyControl=txtPasswordEndLong，Max=15，Min=1

19 CommonDialog Name=Dialog，DialogTitle=请选择加密的Excel或Word文档

Filter=Excel(*.xls)，Word(*.doc)|*.xls;*.doc

20 Label Name=Label1， Caption=破解进度：

21 Label Name=Label3，Caption=从：

22 Label Name=Label5，Caption=到：

⑶为以上对象编写下列代码

为了便于，程序中增加了适当的注释。理解Option Explicit

Private Sub CmdBrowse_Click()

Dialog.ShowOpen 'show the dialog

Combo1.Text = Dialog.FileName 'set the Filename text box to the selected file Combo1.Refresh

End Sub
