%description
The rngd daemon acts as a bridge between a Hardware TRNG (true random number
generator) such as the ones in some Intel/AMD/VIA chipsets, and the kernel's
PRNG (pseudo-random number generator).

It tests the data received from the TRNG using the FIPS 140-2 (2002-10-10)
tests to verify that it is indeed random, and feeds the random data to the
kernel entropy pool.

This increases the bandwidth of the /dev/random device, from a source that
does not depend on outside activity.  It may also improve the quality
(entropy) of the randomness of /dev/random.

A TRNG kernel module such as hw_random, or some other source of true
entropy that is accessible as a device or fifo, is required to use this
package.
