+# wpa_supplicant depends on strong random number generation being available
+# from the operating system. os_get_random() function is used to fetch random
+# data when needed, e.g., for key generation. On Linux and BSD systems, this
+# works by reading /dev/urandom. It should be noted that the OS entropy pool
+# needs to be properly initialized before wpa_supplicant is started. This is
+# important especially on embedded devices that do not have a hardware random
+# number generator and may by default start up with minimal entropy available
+# for random number generation.
+#
+# As a safety net, wpa_supplicant is by default trying to internally collect
+# additional entropy for generating random data to mix in with the data fetched
+# from the OS. This by itself is not considered to be very strong, but it may
+# help in cases where the system pool is not initialized properly. However, it
+# is very strongly recommended that the system pool is initialized with enough
+# entropy either by using hardware assisted random number generator or by
+# storing state over device reboots.
+#
+# wpa_supplicant can be configured to maintain its own entropy store over
+# restarts to enhance random number generation. This is not perfect, but it is
+# much more secure than using the same sequence of random numbers after every
+# reboot. This can be enabled with -e<entropy file> command line option. The
+# specified file needs to be readable and writable by wpa_supplicant.
+#
+# If the os_get_random() is known to provide strong random data (e.g., on
+# Linux/BSD, the board in question is known to have reliable source of random
+# data from /dev/urandom), the internal wpa_supplicant random pool can be
+# disabled. This will save some in binary size and CPU use. However, this
+# should only be considered for builds that are known to be used on devices
