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