Is there any way to lock a folder from terminal(protected with password) without using any third party applications like truecrypt,crypteeper nor giving user permissions.
It was just like whenever a user try to open that folder,it suddenly prompt for password.The given password must not be similar to sudo password.
May be too naive but how about the following:
Let Dir be the directory to be password protected with password qwerty.
mv -n Dir qwerty
mkdir Dir
mv qwerty Dir/.
chmod a-r Dir
This just creates a folder called querty inside Dir with the contents of Dir and removes read permissions to Dir.
To access from terminal:
cd Dir/qwerty
or
cd Dir/
cd qwerty/
Note that pressing tab or typing ls won't reveal qwerty. In other words you need to know qwerty to reach the original contents of Dir.
To access from nautilus:
Navigate to Dir. Press Ctrl+L. Type qwerty in the location bar to enter.
Changing password:
cd Dir
mv qwerty newpassword
This method has quite a few issues.
Dir which depend on their exact location in the filesystem won't work properly.Apart from these there could be other security flaws: this was never intended to be an encryption scheme. That said, from the sound of the question, I guess this might be sufficient.
