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