how can i block my excel file from password cracking. Is there a way/function that can remove all formulas when someone cracks the password.

推荐答案

否。



当数据文件上的密码被破解时，所发生的一切就是用户在软件方面有效地猜测了密码 - 它无法区分您合法输入密码，以及海盗非法输入密码。因此，除非您希望在需要自己打开文件时删除公式...



相反，使用强密码 - 这些确实很难破解任何方式的密码（不是不可能，但非常耗时）。在此处尝试使用现有密码： https://howsecureismypassword.net/ [ ^ ]它会让你知道破解它需要多长时间。

然后将它与这个比较： 2285c451-efba-4ec7-8b2e-9c5b7999e1b1这是一个GUID值......

No.

When a password is "cracked" on a datafile, all that happens is that the user has effectively "guessed" the password as far as the software is concerned - it can't tell the difference between you legitimately entering the password, and the pirate illegally entering the password. So unless you want the formulas removed whenever you need to open the file yourself...

Instead, use Strong passwords - these make it very difficult indeed to "crack" a password by any means (not impossible, but very time consuming). Try your existing password here: https://howsecureismypassword.net/[^] and it will give you an idea how long it would take to "crack" it.
Then compare it with this one: "2285c451-efba-4ec7-8b2e-9c5b7999e1b1" which is a GUID value...
