Well, i dont "have to" do it, iam just playing with this for fun. Brute force is a bit boring. So heres my implementation of finding the seeds from 10+ output values and probably too terse description of how that works. But bascially it iterates over the 17-19 MSB of a compute the corresponding MSB of b and c from that (c requires us to explore multiple cases) and then move around so we split the now "known" part of c so the lower part becomes the MSB of c and then check that. That allows us to discard...

Hi all Wasnt sure i should start a new thread but i guess as its about sfc64 this would reach people interrested. I was playing around first wondering how hard it would be to find the seeds from the output and then instead looking for patterns in the output based on my plan on how to find the seeds from the output. The shortest code i found that shows statistical defects in sfc64 i got after maybe an hour today of looking into it is this: uint64_t v1 = 0, v0 = 0, c = 0, a = 0; for (int i = 0; i<128;...
