This function:
(1366.0*r1+150889)%714025
implements a known method to get random numbers. I think it comes from
"Numerical recipes" by William Press.
Note that the algorithm is not tied to that function, it could be
replaced by something else (especially one that involves a private
key), but it has to be carefully chosen or the end result won't look so
random.
