%description
Using the Jitter RNG core, the rngd provides an entropy source that feeds into
the Linux /dev/random device if its entropy runs low. It updates the
/dev/random entropy estimator such that the newly provided entropy unblocks
/dev/random.

The seeding of /dev/random also ensures that /dev/urandom benefits from
entropy. Especially during boot time, when the entropy of Linux is low, the
Jitter RNGd provides a source of sufficient entropy.

By using the SP800-90B-compliant Jitter RNG core library, the RNGd itself is
now fully SP800-90B compliant.
