+.B \-\-use-prediction-resistance
+Enable prediction resistance on PolarSSL's RNG.
+
+Enabling prediction resistance causes the RNG to reseed in each
+call for random. Reseeding this often can quickly deplete the kernel
+entropy pool.
+
+If you need this option, please consider running a daemon that adds
+entropy to the kernel pool.
+
+Note that this option only works with PolarSSL versions greater
+than 1.1.
