Subject: [PATCH 1/1] salsa20: Salsa20 stream cipher

This patch implements the Salsa20 stream cipher using the blkcipher interface.

The core cipher code comes from Daniel Bernstein's submission to eSTREAM:
http://www.ecrypt.eu.org/stream/svn/viewcvs.cgi/ecrypt/trunk/submissions/salsa20/full/ref/

The test vectors comes from:
http://www.ecrypt.eu.org/stream/svn/viewcvs.cgi/ecrypt/trunk/submissions/salsa20/full/

It has been tested successfully with "modprobe tcrypt mode=34" on an
UML instance.

I was going to apply this but you didn't give a Signed-off-by
header. Please follow the instructions in Documentation/SubmittingPatches.

Thanks,

Patch applied. Thanks for the quick response!

BTW I made a small change to the Kconfig file so that it now selects
BLKCIPHER instead of ALGAPI.

Cheers,
