222# hostapd depends on strong random number generation being available from the
223# operating system. os_get_random() function is used to fetch random data when
224# needed, e.g., for key generation. On Linux and BSD systems, this works by
225# reading /dev/urandom. It should be noted that the OS entropy pool needs to be
226# properly initialized before hostapd is started. This is important especially
227# on embedded devices that do not have a hardware random number generator and
228# may by default start up with minimal entropy available for random number
229# generation.
230#
231# As a safety net, hostapd is by default trying to internally collect
232# additional entropy for generating random data to mix in with the data
233# fetched from the OS. This by itself is not considered to be very strong, but
234# it may help in cases where the system pool is not initialized properly.
235# However, it is very strongly recommended that the system pool is initialized
236# with enough entropy either by using hardware assisted random number
237# generator or by storing state over device reboots.
238#
239# hostapd can be configured to maintain its own entropy store over restarts to
240# enhance random number generation. This is not perfect, but it is much more
241# secure than using the same sequence of random numbers after every reboot.
242# This can be enabled with -e<entropy file> command line option. The specified
243# file needs to be readable and writable by hostapd.
244#
245# If the os_get_random() is known to provide strong random data (e.g., on
246# Linux/BSD, the board in question is known to have reliable source of random
247# data from /dev/urandom), the internal hostapd random pool can be disabled.
