  • summary changed from [with patch, needs review] allow finite field elements in SBox constructor to [with patch, positive review] allow finite field elements in SBox constructor.

The code does something that looks reasonable, and doctests pass. (I don't know enough crypto to be sure that this is a useful thing to do, so I'm relying on malb for that part.)

Positive review.
