Then as in RFC 1750 6.1.1 A Trivial Mixing Function (page 14), make a 3rd bit file stream such that We xor For i=0 to n bit(i)file3=bit(i)file1 (xor) bit(i) file2 and follow idea 1? Is the problem solved and idea 1 worthy? Regards Data. __________________________________________________ Do You Yahoo!? Yahoo! Games - play chess, backgammon, pool and more http://games.yahoo.com/
