The one time it's faster to doing checksum/CRC/Hash based comparisons is when the value is already known or cheaply computed. An example of this is when using FTP... some FTP servers can give you the CRC of the file, saving you the time it takes to download the entire file. Another good example is comparing the contents of a ZIP file, where the CRC is stored in the directory header of the ZIP file which saves you the trouble of expanding the file to do byte-by-bytes. -- Marc C.
