comment Why are Fortuna entropy pools reset after a reseed?
Thanks! The explanation about restarting SHA256 makes perfect sense, so that helps it fall into place correctly in my mind - much appreciated.

comment Why are Fortuna entropy pools reset after a reseed?
Well, the question here is more about whether the pools should or shouldn't be reset, based on an example implementation which does reset them. What I want to know is whether the algorithm requires the pools to be reset and what the reasons are for that.

comment Can a LFSR be cryptographically secure?
So effectively the LFSR adds little value, and even if it is reseeded the next value can be predicted after 64 bits are emitted. But I am guessing that it would be very difficult to predict those first 64-bits (assuming a reseed each time)?
