Re: why does RAND_add() take "randomness" as a "double"?

Good options inspired by other cryptographic libraries include:

- Number of bits of entropy passed in call (For example, a
  perfectly balanced coin flipper could provide the 4 byte
  values "head" or "tail" with an entropy of 1 bit).

Let's drop the coin flipper. It was an off hand remark and by now we
all know there ain't no such thing as a good coin flip for rng.

    See Professor Persi Diaconis at Stanford for that :

Bell's theorem and kolmogorov aside get a radiation decay source as
that is really the *only* real rng that we know of.
Or that I know of.   http://www.fourmilab.ch/hotbits/hardware.html
