This is 407# important especially on embedded devices that do not have a hardware random 408# number generator and may by default start up with minimal entropy available 409# for random number generation. 410# 411# As a safety net, wpa_supplicant is by default trying to internally collect 412# additional entropy for generating random data to mix in with the data fetched 413# from the OS. This by itself is not considered to be very strong, but it may 414# help in cases where the system pool is not initialized properly. However, it 415# is very strongly recommended that the system pool is initialized with enough 416# entropy either by using hardware assisted random number generator or by 417# storing state over device reboots. 418# 419# wpa_supplicant can be configured to maintain its own entropy store over 420# restarts to enhance random number generation. This is not perfect, but it is 421# much more secure than using the same sequence of random numbers after every 422# reboot. This can be enabled with -e<entropy file> command line option. The 423# specified file needs to be readable and writable by wpa_supplicant. 424# 425# If the os_get_random() is known to provide strong random data (e.g., on 426# Linux/BSD, the board in question is known to have reliable source of random 427# data from /dev/urandom), the internal wpa_supplicant random pool can be 428# disabled.
