408 1.1 christos # wpa_supplicant depends on strong random number generation being available
409 1.1 christos # from the operating system. os_get_random() function is used to fetch random
410 1.1 christos # data when needed, e.g., for key generation. On Linux and BSD systems, this
411 1.1 christos # works by reading /dev/urandom. It should be noted that the OS entropy pool
412 1.1 christos # needs to be properly initialized before wpa_supplicant is started. This is
413 1.1 christos # important especially on embedded devices that do not have a hardware random
414 1.1 christos # number generator and may by default start up with minimal entropy available
415 1.1 christos # for random number generation.
416 1.1 christos #
417 1.1 christos # As a safety net, wpa_supplicant is by default trying to internally collect
418 1.1 christos # additional entropy for generating random data to mix in with the data fetched
419 1.1 christos # from the OS. This by itself is not considered to be very strong, but it may
420 1.1 christos # help in cases where the system pool is not initialized properly. However, it
421 1.1 christos # is very strongly recommended that the system pool is initialized with enough
422 1.1 christos # entropy either by using hardware assisted random number generator or by
423 1.1 christos # storing state over device reboots.
424 1.1 christos #
425 1.1 christos # wpa_supplicant can be configured to maintain its own entropy store over
426 1.1 christos # restarts to enhance random number generation. This is not perfect, but it is
427 1.1 christos # much more secure than using the same sequence of random numbers after every
428 1.1 christos # reboot. This can be enabled with -e<entropy file> command line option. The
429 1.1 christos # specified file needs to be readable and writable by wpa_supplicant.

434 1.1 christos # disabled. This will save some in binary size and CPU use. However, this
