       | Every modern OS has a secure RNG. Except for the problem of early
       | boot time entropy (which you can avoid if you have the right API
       | calls that block before enough entropy has been collected),
       | there's never been any major problem with those. Otherwise the
       | only problems with RNGs are either simple bugs (i.e. you're not
       | really using the secure RNG) or people calling pseudorandom
       | functions that weren't meant to be used for secure use cases.
