[CRYPTO] lrw: Liskov Rivest Wagner, a tweakable narrow block cipher mode
Main module, this implements the Liskov Rivest Wagner block cipher mode
in the new blockcipher API. The implementation is based on ecb.c.
The LRW-32-AES specification I used can be found at:
http://grouper.ieee.org/groups/1619/email/pdf00017.pdf
It implements the optimization specified as optional in the
specification, and in addition it uses optimized multiplication
routines from gf128mul.c.
Since gf128mul.[ch] is not tested on bigendian, this cipher mode
may currently fail badly on bigendian machines.
