Given the recent potential weaknesses in the SHA and MD families,
I thought it might not be a bad idea to include another hash/digest
algorithm in the kernel.

So here is Whirlpool.  I chose it for a couple of reasons.

o - It is by the same people who did Khazad. I feel pretty good about their work.
o - It has been evaluated by NESSIE
  https://www.cosic.esat.kuleuven.ac.be/nessie/reports/phase1/sagwp3-037_1.pdf
o - NESSIE has accepted it as one of the cryptographic primitives
o - It will be part of an ISO standard in the revised ISO/IEC 10118-3:2003(E) standard, thanks to
NESSIE
o - It is patent free and has an implementation in the public domain.
