On Linux and BSD systems, this works by 227# reading /dev/urandom. It should be noted that the OS entropy pool needs to be 228# properly initialized before hostapd is started. This is important especially 229# on embedded devices that do not have a hardware random number generator and 230# may by default start up with minimal entropy available for random number 231# generation. 232# 233# As a safety net, hostapd is by default trying to internally collect 234# additional entropy for generating random data to mix in with the data 235# fetched from the OS. This by itself is not considered to be very strong, but 236# it may help in cases where the system pool is not initialized properly. 237# However, it is very strongly recommended that the system pool is initialized 238# with enough entropy either by using hardware assisted random number 239# generator or by storing state over device reboots. 240# 241# hostapd can be configured to maintain its own entropy store over restarts to 242# enhance random number generation. This is not perfect, but it is much more 243# secure than using the same sequence of random numbers after every reboot. 244# This can be enabled with -e<entropy file> command line option. The specified 245# file needs to be readable and writable by hostapd. 246# 247# If the os_get_random() is known to provide strong random data (e.g., on 248# Linux/BSD, the board in question is known to have reliable source of random 249# data from /dev/urandom), the internal hostapd random pool can be disabled. 250# This will save some in binary size and CPU use.
