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