And why I always favoured SHA1 instead of CRC. I don't have vast knowledge on the subject, but SHA1 seems more standardised than CRC. At least with the tests I have done, using various SHA1 implementations, they gave me consistent results. I know this doesn't help your cause Juha. I too read that article you quoted, and was very impressed by the speed increase of the SSE enabled CRC, but returning different results makes it unusable with existing code and stored CRC values - at least you spotted that part too. ;-) Regards, - Graeme - -- fpGUI Toolkit - a cross-platform GUI toolkit using Free Pascal http://fpgui.sourceforge.net/ _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
