| ability to reseed it.</p> |
| <p><code>ReseedingRng</code> reseeds the underlying PRNG in the following cases:</p> |
| <ul> |
| <li>On a manual call to <a href="struct.ReseedingRng.html#method.reseed"><code>reseed()</code></a>.</li> |
| <li>After <code>clone()</code>, the clone will be reseeded on first use.</li> |
| <li>When a process is forked on UNIX, the RNGs in both the parent and child |
| processes will be reseeded just before the next call to |
| <a href="../../../rand_core/block/trait.BlockRngCore.html#tymethod.generate" title="BlockRngCore::generate"><code>BlockRngCore::generate</code></a>, i.e. “soon”. For ChaCha and Hc128 this is a |
| maximum of fifteen <code>u32</code> values before reseeding.</li> |
| <li>After the PRNG has generated a configurable number of random bytes.</li> |
| </ul> |
| <h2 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></h2> |
| <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="struct.ReseedingRng.html#method.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> |
| <h2 id="limitations" class="section-header"><a href="#limitations">Limitations</a></h2> |
| <p>It is recommended that a <code>ReseedingRng</code> (including <code>ThreadRng</code>) not be used |
| from a fork handler. |
| Use <code>OsRng</code> or <code>getrandom</code>, or defer your use of the RNG until later.</p> |
| <h2 id="error-handling" class="section-header"><a href="#error-handling">Error handling</a></h2> |
| <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="struct.ReseedingRng.html#method.reseed"><code>reseed()</code></a> will not have this retry or delay logic, but |
| reports the error.</p> |
