I've been rather continually pinging people, asking them for an
explanation as to the design decisions of Whirlpool (namely -- it's
similar but noticably not identical to AES/Rijndael, and isn't just a
straightforward expansion of the block size up to 512 bits). I'm not
saying anything bad about Whirlpool, but I get alot of people
approaching me about the hash and I don't really know what to tell them.
