460# wpa_supplicant depends on strong random number generation being available
461# from the operating system. os_get_random() function is used to fetch random
462# data when needed, e.g., for key generation. On Linux and BSD systems, this
463# works by reading /dev/urandom. It should be noted that the OS entropy pool
464# needs to be properly initialized before wpa_supplicant is started. This is
465# important especially on embedded devices that do not have a hardware random
466# number generator and may by default start up with minimal entropy available
467# for random number generation.
468#
469# As a safety net, wpa_supplicant is by default trying to internally collect
470# additional entropy for generating random data to mix in with the data fetched
471# from the OS. This by itself is not considered to be very strong, but it may
472# help in cases where the system pool is not initialized properly. However, it
473# is very strongly recommended that the system pool is initialized with enough
474# entropy either by using hardware assisted random number generator or by
475# storing state over device reboots.
476#
477# wpa_supplicant can be configured to maintain its own entropy store over
478# restarts to enhance random number generation. This is not perfect, but it is
479# much more secure than using the same sequence of random numbers after every
480# reboot. This can be enabled with -e<entropy file> command line option. The
481# specified file needs to be readable and writable by wpa_supplicant.
482#
483# If the os_get_random() is known to provide strong random data (e.g., on
484# Linux/BSD, the board in question is known to have reliable source of random
485# data from /dev/urandom), the internal wpa_supplicant random pool can be
