title: What java.security.egd option is for?
body: <p>In a project I'm working on, the application is launched using a command similar to this:</p>
  
  <pre><code>java -Djava.security.egd=file:/dev/urandom -jar app.jar
  </code></pre>
  
  <p>I've never seen the <code>java.security.egd</code> option before. Searching a bit, it seems to be used to configure random number generation in a Java application.</p>
  
  <p>Is it right? When is it supposed to be applied?</p>
