Add stricter checking on mac key lengths.

Authored by jhb on Jan 8 2020, 8:01 PM.



Negative lengths are always invalid. The key length should also
be zero for hash algorithms that do not accept a key.

Test Plan
  • cryptocheck passes
  • test program that provokes a panic with a length of -1 now fails with an error
