EXCEL的密码相关

1 test1.xlsx修改后缀名为test1.rar 或者test1.zip (只是改后缀,不是真压缩!)

2 双击test1.rar,打开文件
- 找到xl,这里是存的xl表格相关
- 其中workbook.xml是工作簿,如果要解的密码是这一层就打开这个文件
- 而worksheets存的是 sheet.xml,如果是解开的某sheet的,找到哪个sheet



3 查找关键词
- 现在一般是MD5加密,找到如下这些关键词
- protect
- sha-512
- hash
- 等等
- 删掉这个<> 之间内容,这些就类html的一句语句,删掉


<workbookProtection workbookAlgorithmName="SHA-512" workbookHashValue="by3TMLq1syl1z5xB8YUw7icytH4gHnr1Keqg4MB5sa4YWh33wnx4VPJZK4+/Mo+YoUV4Km/G6wROivU2xDryZg==" workbookSaltValue="vM+iGfEswjNoYO+jzFzoYw==" workbookSpinCount="100000" lockStructure="1"/>
4 保存 / 另存为新的文件
- 直接保存为新文件
- 另存为新文件,然后保存,替换这个文件
5 test1.rar 或者test1.zip 重新修改后缀名为 xlsx 或 xlsm(以前的名字)
6 亲测好使,但是有些表的加密不行,可能更复杂
