How to setup the use of a USB pen drive as a key for an ecryptfs private directory

(i) Please refer to EncryptedFilesystems for further documentation.

Partition and format the USB stick

If it's not already done, you'll want to partition and format a filesystem to be used to hold the key data from ecryptfs:

 # fdisk /dev/sdb
 # mkfs.ext3 /dev/sdb1

Copy your .ecryptfs to the USB stick

Mount the pen drive on a temporary path, then copy .ecryptfs from your home directory to the temporary mountpoint.

 # mount /dev/sdb1 /mnt
 # cp -a /home/USERNAME/.ecryptfs/* /mnt
 # umount /mnt

Obtain the device's UUID

This step is required for automatizing the mounting of the pen drive to the proper path on boot.

 # blkid /dev/sdb1

Automatize

To mount on boot

Add the following line to /etc/fstab to mount the USB pen drive to the proper directory on boot:

 UUID=<UUID from blkid> /home/<username>/.ecryptfs          ext3     relatime        0       2

To mount on connection

There has to be a way to do this...
