title: Will hashing a UUID with CRC32 be always unqiue?
body: <p>For example, I have a UUID 3f107c44-336c-409b-b6d8-889d552a5339, if I hash it with a CRC32, can I ensure none of the hash of UUID will collapse?</p>
  
  <p>=========</p>
  
  <p>Reason I wanted to ask this is because I was uncertain if I am correct.</p>
  
  <p>What I really wanted to do is to generate a unique id based on an existing unique id.</p>
