Re: A patch to loop.c for better cryption support

[Ingo Rohloff]

Hi

Please have a look at
http://www.in.tum.de/~rohloff

I put two implementations of twofish on the site
and also a modified loop.c 
(which uses requested sector number as IV and
 fixes another problem with xfer->lock and unlock.)

The first implementation of twofish basically
uses an IV seed which is added to the requested 
sector number to get a per sector IV.

The second implementation encrypts the sector number
with the key to get a per sector IV.

(Look at the source for the exact details.)

The implementation should build without modifying
your linux-kernel source tree, so testing should
be easy.
 
Please get it and give me some feedback.

so long
  Ingo

PS: The web site is slow :-( but it should work.
