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.)"
