            fmd5 = hashlib.md5 (reached, f.read () encode ( "UTF-. 8").) reached, f.read ## () read out unicode data is encoded format, and

# Hashlib.md5 not recognize this format, it is necessary to perform encoding format, such as utf-8, gb2312 like 

            return fmd5.hexdigest () ## returns the signature file 
        the except Exception AS E: 
            logger.info ( "% S = error", the repr (E))
