That *is* math. If a judge has ruled that it isn't, he doesn't know what the
hell he's talking about. The bitstream A, the key B, and the output are
mathematical objects, and the "method" is a mathematical algorithm. Unless
it involves measuring the local wind velocity or some other non-mathematical
Everything I said remains true. If a judge really has ruled that that isn't a
mathematical method, then there is indeed caselaw which is wrong as a matter
of fact. Which would suck, but there you are.
