title: Do all MD5 hexadecimal hash representations start with a number?
body: <p>Whenever I hash a name of a file with MD5 (the file was just uploaded and given a MD5 hashed name) the hexadecimal representation of the hash always starts with a number. </p>
  
  <p>Is this a coincidence of the few files I have on my server, or is this a normal case?</p>
