Excel xlsx password - remove or crack?
提问by Hymano058
I have a excel file and set a password by 'bashing' at they keyboard..
我有一个 excel 文件，并通过在键盘上“猛击”来设置密码。
I was basically testing it and pressed everything.. Got me thinking, Is they a way to crack/remove the password?
我基本上是在测试它并按下所有东西..让我想，他们是一种破解/删除密码的方法吗？
I'm not on about just a sheet, I mean the actual file..
我不只是在一张纸上，我的意思是实际文件..
When I click to open the xlsx file a pop up box comes up asking for the password.. Easy way around it?
当我单击打开 xlsx 文件时，会出现一个要求输入密码的弹出框.. 简单的方法吗？

No there isn't. An xlsx(which is essentially a zipfile) uses a far superior encryption model than earlier Excel formats (e.g. xls). In short, the wholefile is encrypted as opposed to a password hash being embedded in an otherwise readable file.
不，没有。An xlsx（本质上是一个zip文件）使用比早期 Excel 格式（例如xls）优越得多的加密模型。简而言之，整个文件是加密的，而不是嵌入在其他可读文件中的密码哈希。
Your only hope is to write a brute force cracker that mimics the bashing behaviour you describe. (e.g. unlikely that you have mixed case etc.).
您唯一的希望是编写一个模仿您描述的攻击行为的蛮力破解程序。（例如，您不太可能有大小写混合等）。
