We are using EncFS. It provides an encrypted filesystem in user-space.
You may need to load fuse module:
#apt-get install encfs
Optionally you may install (EncFS system tray applet for GNOME):
#apt-get install cryptkeeper
encfs [options] rootDir mountPoint
Here I am creating a root folder name encrypt for storing encrypted files.
Also creating a mount point folder named decrypt, which we will use to read/write files.
$encfs ~/.encrypt ~/decrypt
It will ask permission for creating the directory – type y here.
Now, it will ask for expert or pre-configured mode – use pre-configured – type p here.
It will ask for a password. Use a secure password here.
done! now you can use decrypt folder as an encrypted folder.
The actual data will be stored under .encrypt folder, and will be available via decrypt folder after mounting via encfs.
You may unmount it using:
$fusermount -u ~/decrypt
