Feature Request - Enable Use of Encrypted USB Disks

EDIT : oups sorry was taken to the wrong thread, I was talking about ReadyNas.... will post over there, I'll leave it here in case it helps someone.

Hello,

I would like to add my vote to this feature.

It would be in my opinion relatively easy to add this feature, as the package is available for debian Jessie as Luks is available in apt-get :

We can then create LUKS volume on USB disks, and allow automatic unlocking if a special keyfile is present.

I manually did it with a cron task that unlocks the luks volume then mount the partition, does a rsync, and then unmounts and locks the volume. I just had a surprise that if the mount operation did not work correctly I had to check for the disk, else the 4GB root partition fills up very quickly!

Here is my CRON task :

file : /media/mount_rsync_umount.sh

cryptsetup -d /secure/keyfile.luks luksOpen /dev/sdj1 LUKS0001

cryptsetup -d /secure/keyfile.luks luksOpen /dev/sdh1 LUKS0001

cryptsetup -d /secure/keyfile.luks luksOpen /dev/sdg1 LUKS0001

cryptsetup -d /secure/keyfile.luks luksOpen /dev/sdi1 LUKS0001

cryptsetup -d /secure/keyfile.luks luksOpen /dev/sdk1 LUKS0001

mount /dev/mapper/LUKS0001 /media/sdg1

mount /dev/mapper/USB /media/sdg1

rsync -av --exclude-from '/media/exclude-list.txt' "/VOLUME" "/media/sdg1/" > /VOLUME/RSYNC_LOGS/log.log

umount /media/sdg1

cryptsetup luksClose /dev/mapper/LUKS0001

cryptsetup luksClose /dev/mapper/USB

sorry if it not very clean I am not a full time Debian/Bash admin :)

Hope it helps!
