I also think that hashtable keys are usualy too small by several
magnitudes to benefit from it. The cost of setting up the hardware
crypto engine from userspace will be way higher than hashing e.g. 64
byte yourself. I would expect that anything below page size at least
won't be faster in hardware but that is just a guess.
