Hello Sebastian,
Thanks for your review of the patch. I will address your points below.

Hello list (cc: Herbert, Christoph),
In my previous mail you will find a proposed patch to
implement XTS (a block cipher mode alike LRW, but unlike
LRW, no known security problems (LRW has problems encrypting
it's own key)). An email from Cristoph sparked my interest,
and the lrw.c file was a good

WARNING: untested on bigendian, please test.
A lot of cypher modes need multiplications in GF(2^128). LRW, ABL, GCM...
I use functions from this library in my LRW implementation and I will
also use them in my ABL (Arbitrary Block Length, an unencumbered (correct
Hello Herbert/list,
Here is the updated version of my LRW patch set.
Greetings,

Just some minor comment nits.
- little-endian is better than low-endian
- and since it is called essiv everywere it should also be essiv

LRW-32-AES needs a certain IV. This IV should be provided dm-crypt.
The block cipher mode could, in principle generate the correct IV from
the plain IV, but I think that it is cleaner to supply the right IV
directly.
The sector -> narrow block calculation uses a

128bit is a common blocksize in linux kernel cryptography, so it helps to
centralize some common operations. The data must be aligned at sizeof(int)
for decent performance.
The code, while mostly trivial, is based on a header file mode_hdr.h in
