[openssl-users] PRNG is not seeded

[FooCrypt]

Are you a Dr Who fan ?

Place a teaspoon of fine grade white sand onto the skin of a snare drum

Place an isolating isoscrope above the snare drum that can measure the fractional movements of the grains of sand based on the ambient noise.

Do something that moves the sand so you can measure the factorial movements based on different events.

There was a documentary on the ABC about it all a few years back, someone at ANU or somewhere else in Oz was woking on the research.
