title: Convert string to hash and then reform the string later
body: <p>I need to hash some strings so I can pass them into some libraries, this is straight forward using the String.hashCode call. </p>
  
  <p>However once everything is processed I'd like to convert the integer generated from the hashCode back into the String value. I could obviously track the string and hashcode values somewhere else and do the conversion there, but I'm wondering is there anything in Java that will do this automatically.</p>
