&quot;But this is nonsense! Those 1024 bits you added before aren&#x27;t depleted just because you pulled 1024 from &#x2F;dev&#x2F;random!&quot;<p>An observer of the produced random numbers can potentially deduce the next numbers from the first 1024 random numbers. This is the reason why &#x2F;dev&#x2F;random requires more randomness added -- to prevent the guessing of the next number.
