Thanks!
Will try it on a temporary dir first.

Interested in how to do it?
I got an email off-list to post the instructions. Again: I created the
container around ten years ago. Did it on Debian. But used that approach
for years once I created this container.
Here we go (Read the notes at the end, please):
----------------------------------------------------------------------->
Making an ecrypted file container:
$ nice -+19 /usr/bin/dcfldd bs=1M count=6000 statusinterval=10 if=/dev/urandom
of=/home/<your.user.name>/encrypt.ctr
# losetup /dev/loop0 /home/<your.user.name>/encrypt.ctr
# cryptsetup --verbose --verify-passphrase --cipher aes-xts-benbi --key-size
512 luksFormat /dev/loop0
# cryptsetup luksOpen /dev/loop0 encfs
# /sbin/mkfs.ext3 -j -O dir_index,filetype,sparse_super /dev/mapper/encfs
# chown <your.user.name>:<your.user.name> /home/<your.user.name>/enc
# chmod 0700 /home/<your.user.name>/enc
added to fstab this line
/dev/mapper/encfs /home/<your.user.name>/enc ext3
user,noauto,rw,dev,exec,suid 0 0
Backup before:
# cp /etc/fstab~ /etc/fstab.2008.12.21
`/etc/fstab~' -> `/etc/fstab.2008.12.21'
mount:
# losetup /dev/loop0 /home/<your.user.name>/encrypt.ctr
# cryptsetup luksOpen /dev/loop0 encfs
as <your.user.name>:
$ mount enc/
umount:
$ umount enc/
# cryptsetup luksClose encfs
# losetup -d /dev/loop0
<-------------------------------------------------------------------------------------
A few short notes (it's late, I want some sleep ..)
0:
the stuff after the 'mount'/'umount' lines is what I did to
activate/deactivate the container after logging in.
1:
"--cipher aes-xts-benbi" - I'd change that to a cipher you want. I
think aes-xts-benbi is oldand not be what you want today ....
2:
$ nice -+19 /usr/bin/dcfldd bs=1M count=6000 statusinterval=10 if=/dev/urandom
of=/home/<your.user.name>/encrypt.ctr
"bs=1M count=6000" : should create a container size of 6000Mb ..
3:
IIRC:
'#' from above: done as root; '$' done as <your.user.name>
4:
In your /home dir I think you should do this - probably wasn't created
automatically via fstab:
mkdir enc
so /home/<your.user.name>/enc is simply the mount point for your
encrypted container, IIRC ...
I got these instructions from somewhere on the internets. Not my
work, IIRC. Just tried and probably modified it. And successfully.
Good luck, all!
Wolfgang
