|

<p><code>ReseedingRng</code> reseeds the underlying PRNG in the following cases:</p>
|
|
|
<ul>
|
|
|
<li>On a manual call to <a href="ReseedingRng::reseed"><code>reseed()</code></a>.</li>
|
|
|
<li>After <code>clone()</code>, the clone will be reseeded on first use.</li>
|
|
|
<li>After a process is forked, the RNG in the child process is reseeded within
|
|
|
the next few generated values, depending on the block size of the
|
|
|
underlying PRNG. For <a href="rand_chacha::ChaChaCore"><code>ChaChaCore</code></a> and <a href="rand_hc::Hc128Core"><code>Hc128Core</code></a> this is a maximum of
|
|
|
15 <code>u32</code> values before reseeding.</li>

<li>After the PRNG has generated a configurable number of random bytes.</li>

<h1 id="when-should-reseeding-after-a-fixed-number-of-generated-bytes-be-used" class="section-header"><a href="#when-should-reseeding-after-a-fixed-number-of-generated-bytes-be-used">When should reseeding after a fixed number of generated bytes be used?</a></h1>
|
|
|
<p>Reseeding after a fixed number of generated bytes is never strictly
|
|
|
<em>necessary</em>. Cryptographic PRNGs don't have a limited number of bytes they
|
|
|
can output, or at least not a limit reachable in any practical way. There is
|
|
|
no such thing as 'running out of entropy'.</p>
|
|
|
<p>Occasionally reseeding can be seen as some form of 'security in depth'. Even
|
|
|
if in the future a cryptographic weakness is found in the CSPRNG being used,
|
|
|
or a flaw in the implementation, occasionally reseeding should make
|
|
|
exploiting it much more difficult or even impossible.</p>
|
|
|
<p>Use <a href="ReseedingRng::new"><code>ReseedingRng::new</code></a> with a <code>threshold</code> of <code>0</code> to disable reseeding
|
|
|
after a fixed number of generated bytes.</p>
|
|
|
<h1 id="error-handling" class="section-header"><a href="#error-handling">Error handling</a></h1>
|
|
|
<p>Although unlikely, reseeding the wrapped PRNG can fail. <code>ReseedingRng</code> will
|
|
|
never panic but try to handle the error intelligently through some
|
|
|
combination of retrying and delaying reseeding until later.
|
|
|
If handling the source error fails <code>ReseedingRng</code> will continue generating
|
|
|
data from the wrapped PRNG without reseeding.</p>
|
|
|
<p>Manually calling <a href="ReseedingRng::reseed"><code>reseed()</code></a> will not have this retry or delay logic, but
|
|
|
reports the error.</p>
