# Example wpa_supplicant build time configuration

# wpa_supplicant depends on strong random number generation being available

# from the operating system. os_get_random() function is used to fetch random

# data when needed, e.g., for key generation. On Linux and BSD systems, this

# works by reading /dev/urandom. It should be noted that the OS entropy pool

# needs to be properly initialized before wpa_supplicant is started. This is

# important especially on embedded devices that do not have a hardware random

# number generator and may by default start up with minimal entropy available

# for random number generation.

#

# As a safety net, wpa_supplicant is by default trying to internally collect

# additional entropy for generating random data to mix in with the data fetched

# from the OS. This by itself is not considered to be very strong, but it may

# help in cases where the system pool is not initialized properly. However, it

# is very strongly recommended that the system pool is initialized with enough

# entropy either by using hardware assisted random number generator or by

# storing state over device reboots.

#

# wpa_supplicant can be configured to maintain its own entropy store over

# restarts to enhance random number generation. This is not perfect, but it is

# much more secure than using the same sequence of random numbers after every

# reboot. This can be enabled with -e<entropy file> command line option. The

# specified file needs to be readable and writable by wpa_supplicant.

#

# If the os_get_random() is known to provide strong random data (e.g., on

# Linux/BSD, the board in question is known to have reliable source of random

# data from /dev/urandom), the internal wpa_supplicant random pool can be

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

# should only be considered for builds that are known to be used on devices
