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