Getting md5sum from a cd.

[IYIaster]

I'm trying to figure out how to get the md5sum of a cd/dvd in Java. This is what I'm doing to get the md5sum of the iso & it works great but, what do I need to change to get the md5sum of the cd so I can compare them.

     public static byte[] createChecksum(String filename) throws
       Exception
   {
     InputStream fis =  new FileInputStream(filename);

     byte[] buffer = new byte[1024];
     MessageDigest complete = MessageDigest.getInstance("MD5");
     int numRead;
     do {
      numRead = fis.read(buffer);
      if (numRead > 0) {
        complete.update(buffer, 0, numRead);
        }
      } while (numRead != -1);
     fis.close();
     return complete.digest();
   }

   public static String getMD5Checksum(String filename) throws Exception {
     byte[] b = createChecksum(filename);
     String result = "";
     for (int i=0; i < b.length; i++) {
       result +=
          Integer.toString( ( b[i] & 0xff ) + 0x100, 16).substring( 1 );
      }
     return result;
   }
