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