title: Fastest ASP.NET hash function for hashing filenames
body: <p>I'm trying to optimize my ASP.NET thumbnailing script, so it doesn't resize all the images all the time, and one part of the problem is choosing the hash function for the thumbnail naming/checking procedure.</p>
  
  <p>Is crc32 up to the task? I'm asking cause the input data is small (only relative path, size and date).</p>
