On Linux and BSD systems, this 404# works by reading /dev/urandom. It should be noted that the OS entropy pool 405# needs to be properly initialized before wpa_supplicant is started. This is 406# important especially on embedded devices that do not have a hardware random 407# number generator and may by default start up with minimal entropy available 408# for random number generation. 409# 410# As a safety net, wpa_supplicant is by default trying to internally collect 411# additional entropy for generating random data to mix in with the data fetched 412# from the OS. This by itself is not considered to be very strong, but it may 413# help in cases where the system pool is not initialized properly. However, it 414# is very strongly recommended that the system pool is initialized with enough 415# entropy either by using hardware assisted random number generator or by 416# storing state over device reboots. 417# 418# wpa_supplicant can be configured to maintain its own entropy store over 419# restarts to enhance random number generation. This is not perfect, but it is 420# much more secure than using the same sequence of random numbers after every 421# reboot. This can be enabled with -e<entropy file> command line option. The 422# specified file needs to be readable and writable by wpa_supplicant. 423# 424# If the os_get_random() is known to provide strong random data (e.g., on 425# Linux/BSD, the board in question is known to have reliable source of random 426# data from /dev/urandom), the internal wpa_supplicant random pool can be 427# disabled.

However, this 428# should only be considered for builds that are known to be used on devices 429# that meet the requirements described above. 430 431# Wpa_supplicant's random pool is not necessary on Android.
