On Linux and BSD systems, this works by 218 # reading /dev/urandom. It should be noted that the OS entropy pool needs to be 219 # properly initialized before hostapd is started. This is important especially 220 # on embedded devices that do not have a hardware random number generator and 221 # may by default start up with minimal entropy available for random number 222 # generation. 223 # 224 # As a safety net, hostapd is by default trying to internally collect 225 # additional entropy for generating random data to mix in with the data 226 # fetched from the OS. This by itself is not considered to be very strong, but 227 # it may help in cases where the system pool is not initialized properly. 228 # However, it is very strongly recommended that the system pool is initialized 229 # with enough entropy either by using hardware assisted random number 230 # generator or by storing state over device reboots. 231 # 232 # hostapd can be configured to maintain its own entropy store over restarts to 233 # enhance random number generation. This is not perfect, but it is much more 234 # secure than using the same sequence of random numbers after every reboot. 235 # This can be enabled with -e<entropy file> command line option. The specified 236 # file needs to be readable and writable by hostapd. 237 # 238 # If the os_get_random() is known to provide strong random data (e.g., on 239 # Linux/BSD, the board in question is known to have reliable source of random 240 # data from /dev/urandom), the internal hostapd random pool can be disabled. 241 # This will save some in binary size and CPU use.
