Frequently asked questions

What is the difference between the two passwords?
打开密码 (user) is required to open the file. 权限密码 (owner) controls editing restrictions β€” we generate a random one unless you provide it, so restrictions cannot be casually lifted.
How strong is the encryption?
AES-256, the current standard. Choose a password of 8+ characters mixing letters and numbers.
What if I forget the password?
There is no recovery β€” that is the point of encryption. Keep the password with the file.

When this tool is not the right choice

You need audit trails and revocable access.
Use a document platform with access control β€” static encryption cannot revoke.
