Even if sha and md5 are very strong, weak use are still in place in V42, Ethernet, FDDI, ZIP and PNG They all use a CRC I think we should allow a new value for algorithm 'crc' with three parameters provided on 'parameters' port : * size in bits (integer) * polynom as a String (or hexBinary) * polynom-form as a string amongst ("Normal", "Reverse" or 'NormalOfReciprocal") Option 1 : we could say there is no default so you need to provide the parameters Option 2 : we could say that if no parameters are provided, then it will be defaulted to size=32, polynom=0xEDB88320 and polynom-form=Reverse (which is CRC-32-IEEE 802.3 used in V42, MPEG 2 and PNG) Regards, Mohamed -- Innovimax SARL Consulting, Training & XML Development 9, impasse des Orteaux 75020 Paris Tel : +33 9 52 475787 Fax : +33 1 4356 1746 http://www.innovimax.fr RCS Paris 488.018.631 SARL au capital de 10.000 €Received on Thursday, 1 May 2008 09:26:06 GMT
