Hi,

I found many guides on harddisk encryption with
cryptsetup-LUKS but none of them clarifies if it makes sense
to use a hash-function (like sha256) with xts-plain. I would
appreciate any hint.

Best,
Jehovah

Hi again,

am I mistaken to assume that there are only 3 correct
combinations?

anycipher-cbc-essiv:sha256
anycipher-lrw-benbi
anycipher-xts-plain

I've found a mailinglist-post stating that it's also
possible to use anycipher-xts-benbi. Are there any
security-advantages using this?

Best,
Jehova

There are two wikipedia articles which explain disk
encryption theory in
general:

h
ttp://en.wikipedia.org/wiki/Disk_encryption_theory
http://en.wikipedia.org/wiki/Block_cipher_modes_of_o
peration

The latter is particularly good and illustrates the problem
with naive
ECB mode using pictures.

I hope this helps
