+  urngd is OpenWrt's micro non-physical true random number generator based on
+  timing jitter.
+
+  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.
