encrypting the users' folders
Currently, the default setting is that root can see and modify
anything, including the contents of the users' folders, moreover,
users can also see the contents of other users' folders by default.
These pose a significant confidentiality and security risk.
Therefore is there any way to encrypt all users' folders and making
the computer to set this up by default when a new user is generated?
So that even the root can't see the contents of the users' folders.
