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 hostapd 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, hostapd 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. # # hostapd 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 command line option. The specified # file needs to be readable and writable by hostapd. # # 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 hostapd random pool can be disabled. # This will save some in binary size and CPU use.
