Well, the Via Padlock has a hardware random-number generator, so the idea was to test that. It doesn't claim to be fast, just to be truly random > > bash-2.05b$ time dd if=/dev/urandom bs=1024 count=10240 of=/dev/null > 10240+0 records in > 10240+0 records out > 10485760 bytes transferred in 0.154649 secs (67803598 bytes/sec) > > bash-2.05b$ time dd if=/dev/urandom bs=8k count=10240 of=/dev/null > 10240+0 records in > 10240+0 records out > 83886080 bytes transferred in 1.165706 secs (71961615 bytes/sec)
