 The table below shows the time for calculating digest of a message as a function of message size size for both SHA-1 and MD-5:

     KEY SIZE = 1024 bits
                                                             TIME in milliseconds
                                           **************************************************************
                Message Size in bytes                    SHA-1                   MD-5   
                   250                                    91			  90
