1# Example wpa_supplicant build time configuration

3# This file lists the configuration options that are used when building the
4# wpa_supplicant binary. All lines starting with # are ignored. Configuration
5# option lines must be commented out complete, if they are not to be included,
6# i.e., just setting VARIABLE=n is not disabling that variable.

405# wpa_supplicant depends on strong random number generation being available
406# from the operating system. os_get_random() function is used to fetch random
407# data when needed, e.g., for key generation. On Linux and BSD systems, this
408# works by reading /dev/urandom. It should be noted that the OS entropy pool
409# needs to be properly initialized before wpa_supplicant is started. This is
410# important especially on embedded devices that do not have a hardware random
411# number generator and may by default start up with minimal entropy available
412# for random number generation.
413#
414# As a safety net, wpa_supplicant is by default trying to internally collect
415# additional entropy for generating random data to mix in with the data fetched
416# from the OS. This by itself is not considered to be very strong, but it may
417# help in cases where the system pool is not initialized properly. However, it
418# is very strongly recommended that the system pool is initialized with enough
419# entropy either by using hardware assisted random number generator or by
420# storing state over device reboots.
421#
422# wpa_supplicant can be configured to maintain its own entropy store over
423# restarts to enhance random number generation. This is not perfect, but it is
424# much more secure than using the same sequence of random numbers after every
425# reboot. This can be enabled with -e<entropy file> command line option. The
426# specified file needs to be readable and writable by wpa_supplicant.
427#
428# If the os_get_random() is known to provide strong random data (e.g., on
429# Linux/BSD, the board in question is known to have reliable source of random
430# data from /dev/urandom), the internal wpa_supplicant random pool can be
431# disabled. This will save some in binary size and CPU use. However, this
432# should only be considered for builds that are known to be used on devices
433# that meet the requirements described above.
434
435# Wpa_supplicant's random pool is not necessary on Android. Randomness is
