A random data generator.
<p>
Data is generated using /dev/urandom, and is cryptographically secure. Unlike rand() and friends, <a class="el" href="classPassenger_1_1RandomGenerator.html" title="A random data generator.">RandomGenerator</a> does not require seeding.<p>
The reason why <a class="el" href="classPassenger_1_1RandomGenerator.html" title="A random data generator.">RandomGenerator</a> isn't a singleton is because opening /dev/urandom is *very* slow on Mac OS X and OpenBSD. Each object of this class caches the /dev/urandom file handle.<p>
This class is thread-safe as long as there are no concurrent calls to reopen() or close(). <hr>The documentation for this class was generated from the following file:<ul>
<li><a class="el" href="RandomGenerator_8h-source.html">RandomGenerator.h</a></ul>
