412 # wpa_supplicant depends on strong random number generation being available
413 # from the operating system. os_get_random() function is used to fetch random
414 # data when needed, e.g., for key generation. On Linux and BSD systems, this
415 # works by reading /dev/urandom. It should be noted that the OS entropy pool
416 # needs to be properly initialized before wpa_supplicant is started. This is
417 # important especially on embedded devices that do not have a hardware random
418 # number generator and may by default start up with minimal entropy available
419 # for random number generation.
421 # As a safety net, wpa_supplicant is by default trying to internally collect
422 # additional entropy for generating random data to mix in with the data fetched
423 # from the OS. This by itself is not considered to be very strong, but it may
424 # help in cases where the system pool is not initialized properly. However, it
425 # is very strongly recommended that the system pool is initialized with enough
426 # entropy either by using hardware assisted random number generator or by
427 # storing state over device reboots.
429 # wpa_supplicant can be configured to maintain its own entropy store over
430 # restarts to enhance random number generation. This is not perfect, but it is
431 # much more secure than using the same sequence of random numbers after every
432 # reboot. This can be enabled with -e<entropy file> command line option. The
433 # specified file needs to be readable and writable by wpa_supplicant.
435 # If the os_get_random() is known to provide strong random data (e.g., on
436 # Linux/BSD, the board in question is known to have reliable source of random
437 # data from /dev/urandom), the internal wpa_supplicant random pool can be
438 # disabled. This will save some in binary size and CPU use. However, this
439 # should only be considered for builds that are known to be used on devices
440 # that meet the requirements described above.
442 # Wpa_supplicant's random pool is not necessary on Android. Randomness is
