title: crc32 decrypt short string
body: <p>I am retrieving lists of crc32 hashes that contain names of files, not there contents.</p>
  
  <p>I need to be able to decrypt the strings which are hashed names like "vacationplans_2010.txt"</p>
  
  <p>which are less then 25 characters long.</p>
  
  <p>is this possible?</p>
