452 # wpa_supplicant depends on strong random number generation being available
453 # from the operating system. os_get_random() function is used to fetch random
454 # data when needed, e.g., for key generation. On Linux and BSD systems, this
455 # works by reading /dev/urandom. It should be noted that the OS entropy pool
456 # needs to be properly initialized before wpa_supplicant is started. This is
457 # important especially on embedded devices that do not have a hardware random
458 # number generator and may by default start up with minimal entropy available
459 # for random number generation.
461 # As a safety net, wpa_supplicant is by default trying to internally collect
462 # additional entropy for generating random data to mix in with the data fetched
463 # from the OS. This by itself is not considered to be very strong, but it may
464 # help in cases where the system pool is not initialized properly. However, it
465 # is very strongly recommended that the system pool is initialized with enough
466 # entropy either by using hardware assisted random number generator or by
467 # storing state over device reboots.
469 # wpa_supplicant can be configured to maintain its own entropy store over
