Hi Harald:

I'm working on making the export format of hash algorithms compatible
so that you can switch between implementations seamlessly.

I've got a question about the s390 hmac implementation.  How does
the hardware tell if it's the first update (where the cv from the
param block contains undefined state) or not? Is it a bit in
s390_kmac_gr0 or is it the imbl?

Thanks,
--
