Whee -- SHA-3 is out! I wanted to explore the new toy a bit, and
so, here is a blatantly untested rough draft of SHA-3 kernel support.
Why rough draft? Because answers to the questions below will inform a
more polished version.
Just to update people... this has been in a holding pattern, because
apparently there are revisions to SHA-3 coming down the pipe. They want
to address preimage resistance, and make things faster in hardware.
Random quote from NIST, on the NIST hash-forum, which doesn't provide
detail but does summarize general feeling: "As best we can tell,
continuing to pay that performance penalty for all future uses of SHA3
has no benefit. (All this is a longwinded way of saying: we were wrong,
but hopefully we got better.)"
