To spike interest: "PadLock ACE encrypts at rates of up to 12.5 Gigabits per second (Gbps) with a 1GHz VIA C3 processor, more than eight times faster than the best software AES implementation from a power hungry 3GHz IntelŪ PentiumŪ 4 processor based system that encrypts at a rate of a mere 1.5 Gbps." 25 times faster, clock by clock :) Regards, Nuno Silva [...] > > P.S.
