HMAC testing with pre-computed key blocks

[jvdsn]

FIPS 198-1, Section 6 specifies that:

Conceptually, the intermediate results of the compression function on the B-byte blocks
(K0 ⊕ ipad) and (K0 ⊕ opad) can be precomputed once, at the time of generation of the
key K, or before its first use.

It would be useful if ACVP could include a test (e.g. maybe an option in the HMAC capabilities registration) for these pre-computed key blocks. Then, instead of providing a key, the ACVP server provides the pre-computed key blocks to the IUT.

@jvdsn, thanks for the suggestion, I'll run it by Chris and find out what can be done. Thanks!
