implementation is supposed to be cryptographically secure.</p>
<p><em>Cryptographically secure generators</em>, also known as <em>CSPRNGs</em>, should
satisfy an additional properties over other generators: given the first
<em>k</em> bits of an algorithm's output
sequence, it should not be possible using polynomial-time algorithms to
predict the next bit with probability significantly greater than 50%.</p>
<p>Some generators may satisfy an additional property, however this is not
required by this trait: if the CSPRNG's state is revealed, it should not be
computationally-feasible to reconstruct output prior to this. Some other
generators allow backwards-computation and are consided <em>reversible</em>.</p>
<p>Note that this trait is provided for guidance only and cannot guarantee
suitability for cryptographic applications. In general it should only be
implemented for well-reviewed code implementing well-regarded algorithms.</p>
<p>Note also that use of a <code>CryptoRng</code> does not protect against other
weaknesses such as seeding from a weak entropy source or leaking state.</p>
