On Linux and BSD systems, this works by 238# reading /dev/urandom. It should be noted that the OS entropy pool needs to be 239# properly initialized before hostapd is started. This is important especially 240# on embedded devices that do not have a hardware random number generator and 241# may by default start up with minimal entropy available for random number 242# generation. 243# 244# As a safety net, hostapd is by default trying to internally collect 245# additional entropy for generating random data to mix in with the data 246# fetched from the OS. This by itself is not considered to be very strong, but 247# it may help in cases where the system pool is not initialized properly. 248# However, it is very strongly recommended that the system pool is initialized 249# with enough entropy either by using hardware assisted random number 250# generator or by storing state over device reboots. 251# 252# hostapd can be configured to maintain its own entropy store over restarts to 253# enhance random number generation. This is not perfect, but it is much more 254# secure than using the same sequence of random numbers after every reboot. 255# This can be enabled with -e<entropy file> command line option. The specified 256# file needs to be readable and writable by hostapd. 257# 258# If the os_get_random() is known to provide strong random data (e.g., on 259# Linux/BSD, the board in question is known to have reliable source of random 260# data from /dev/urandom), the internal hostapd random pool can be disabled. 261# This will save some in binary size and CPU use.
