In order to make effective use of this device driver, you
should download the support software as well. Download the
latest version of the "

Character driver. Using the standard open()
and read() system calls, you can read random data from
the
i810
RNG device. This data is NOT CHECKED by any
the
hardware
RNG device. This data is NOT CHECKED by any
fitness tests, and could potentially be bogus (if the
hardware is faulty or has been tampered with). Data is only
output if the hardware "has-data" flag is set, but nevertheless
a security-conscious person would run fitness tests on the
data before assuming it is truly random.
