The values presented are &quot;N bits per character&quot;.
8 is the maximum, 0 is the minimum.
The less value is the worse.
The ugly test results show that &quot;true&quot;-random tool does not perform better than openssl &#x2F; &#x2F;dev&#x2F;urandom. What makes it even worse is that the entropy decreases with the amount of iterations. These are simple bash tests, you can try on your own, playing with the values. Though, I suggest to understand some theory in the first place:<p>- randomness <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Randomness" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Randomness</a><p>- entropy <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Entropy_(computing)" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Entropy_(computing)</a><p>- ent <a href="http:&#x2F;&#x2F;www.fourmilab.ch&#x2F;random&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.fourmilab.ch&#x2F;random&#x2F;</a>
