I certainly don't want to assist in creating hysteria, nor do I
want to help spread misinformation. I am concerned, however, by
the potential for DESChall's work to be impacted by its emphasis
on Pentium hardware.

Could the possible math bug in the Pentium Pro affect the DES
cracking project? Please reference the following article:,4,10342,00.html



It's not a problem for Deschall, as the bug is in the FPU and
Deschall doesn't use any FPU math just Integer.
