title: how to hash SHA512 string in c #
body: <p>I have this  &quot;mac key&quot; and other parameter and I need it turned into SHA512</p>
  <p>I really need working example code too</p>
  <p>I've gathered that it might have something to do with System.Security.Cryptography's SHA512Managed class, but I don't understand how to use that class  for a c sharp website at all it makes no sense to me that is why I need a working example of it turning a string into SHA512</p>
