For reference, that would be p512 of http://www.amd.com/files/connectivitysolutions/geode/geode_lx/33234E_LX_databook.pdf and chapter 18 of Applied Cryptography, "ONE-WAY HASH FUNCTIONS USING SYMMETRIC BLOCK ALGORITHMS". As a stopgap, using only SHA-512 (and leaving off the whirlpool hash) will more than double our authentication speed. --scott -- ( http://cscott.net/ ) _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
