if one really cared, the right thing to do
would be fastrand() calls.
truerand is only for things that absolutely
must be random (not pseudo-random)
or for seeding random number generators,

all the auth protocols are due for a rework,
but honestly i don't think anyone cares
enough to see it through, myself included.
