title: What is the most secure seed for random number generation?
body: <p>What are the most secure sources of entropy to seed a random number generator?  This question is language and platform independent and applies to any machine on a network.  Ideally I'm looking for sources available to a machine in a cloud environment or server provided by a hosting company.</p>
  
  <p>There are two important weaknesses to keep in mind. The use of time for sending a random number generator is a violation of <a href="http://cwe.mitre.org/data/definitions/337.html" rel="noreferrer">CWE-337</a>.  The use of a small seed space would be a violation of <a href="http://cwe.mitre.org/data/definitions/339.html" rel="noreferrer">CWE-339</a>.</p>
