> Assuming its a permutation and you output the whole thing. I'm assuming the state-mixing function is a permutation (i.e. the counter affects the whole state in a reversible way), but it is not required that the whole state is outputted. > However, you wouldn't output the whole thing (or you instantly leak the state), and I think in that case you don't get an automatic useful guarantee about the period anymore: For some seeds you could have the whole 0..2^64-1 counter span just output a few repeating values (or even a constant). The counter will always have the full period of 2^N (assuming…
