excel后缀名xlsm加密文件破解

1、新建一个EXCEL文件“BOOK1”，在工具栏空白位置，任意右击，选择Visual Basic项，d出Visual Basic工具栏：

2

2、在Visual Basic工具栏尘答桐中，点击“录制”按钮，d出“录制新宏”对话框，选择“个人宏工作簿”： 

3、选择“个人宏工作簿”后按确定，d出如下“暂停”按钮，点击停止： 

4、在Visual Basic工具栏中，点击“编辑”按钮： 

5、点击“编辑”按钮后，d出如下图的编辑界面：

找到“VBAProject（PERSONAL.XLS）－模块－模块1（也可能是模块N-其他数字）”

双击模块1－将右边代码内容清空  

6、复制“工作保护密码破解”代码到右边框中，点保存，然后关闭“BOOK1” 

7、运行需要解密的“EXCEL文件”，在Visual Basic工具栏中，点击“运行”按钮 

8、点击“运行”按钮后，d出“宏”对话框，

点击运行“PERSONAL.XLS!工作保护密码破解”这个宏 

9、运行“PERSONAL.XLS!工作保护密码破解”这个宏后，

如下图示意就可以 解除工作表的密码保护了 

（这个图，如果工举态作表中有多组不同密码，

每解开一组，就会提示一次，也就说可能会出现几次）

<工作表保护密码破解放代码>是放在VBAProject(PERSONAL.XLS)[个人宏工作簿]——[模块]中的，如上图是放在红色标号2[模块1]中

首先，先去唤友下载一款代码编辑器Notepad++

第二步，将待破解的档案后缀名称由.xlsm改为.rar或者.zip

第三步，使用压缩软件打开，进入xl目录找到vbaProject.bin文件

右键【打开】，选择已下载好的代码编辑器Notepad++

第四步，查找字符DPB并将其替换成DPx，保存文件，确定更新，关闭压缩档案，再重新修改后缀名.rar(或者是.zip)为.xlsm

第五步，使用汪唯excel打开.xlsm文件，d出警告框，点击“是”，【开发工具】，【查看代码】，d出未知错误提示框，点击“确定”。【工具】菜单，【VBAProject属性】打开工程属性，切换到【困链培保护】标签，重新填入密码或者不填写密码（不填写密码时不要勾选查看是锁定工程），最后确定。

最后，保存后关闭档案，重新打开档案就可以看到里面的代码了

PS. 破解仅用来学习，但不要挡了别人的财路

e和d是选择出来的， e的选择需要满足gcd(e,160)=1，即互质，7和1 60互质 d的选搭让择需要满足ed mod 160＝1,即ed除以1 60余1，7*23 mod 160=161 mod 160＝1 加拆枝源解密过程的计算 M是需要加密旅态的数据， 加密时C=M^e mod N 所以C＝88^7 mod187＝11 解密时M=C^d mod N 解密时M＝11^23 mod 187＝88
