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 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.
