393 # wpa_supplicant depends on strong random number generation being available
394 # from the operating system. os_get_random() function is used to fetch random
395 # data when needed, e.g., for key generation. On Linux and BSD systems, this
396 # works by reading /dev/urandom. It should be noted that the OS entropy pool
397 # needs to be properly initialized before wpa_supplicant is started. This is
398 # important especially on embedded devices that do not have a hardware random
399 # number generator and may by default start up with minimal entropy available
400 # for random number generation.
402 # As a safety net, wpa_supplicant is by default trying to internally collect
403 # additional entropy for generating random data to mix in with the data fetched
404 # from the OS. This by itself is not considered to be very strong, but it may
405 # help in cases where the system pool is not initialized properly. However, it
406 # is very strongly recommended that the system pool is initialized with enough
407 # entropy either by using hardware assisted random number generator or by
408 # storing state over device reboots.
410 # wpa_supplicant can be configured to maintain its own entropy store over
411 # restarts to enhance random number generation. This is not perfect, but it is
412 # much more secure than using the same sequence of random numbers after every
413 # reboot. This can be enabled with -e<entropy file> command line option. The
