First of all we already have a sync non-SG hash interface, it's
called shash.
If we had enough sync-only users of skcipher then I'll consider
adding an interface for it. However, at this point in time it
appears to more sense to convert such users over to the async
interface rather than the other way around.
As for AEAD we never had a sync interface to begin with and I
don't think I'm going to add one.
Cheers,
