440 # data when needed, e.g., for key generation. On Linux and BSD systems, this
441 # works by reading /dev/urandom. It should be noted that the OS entropy pool
442 # needs to be properly initialized before wpa_supplicant is started. This is

444 # number generator and may by default start up with minimal entropy available
445 # for random number generation.
447 # As a safety net, wpa_supplicant is by default trying to internally collect
448 # additional entropy for generating random data to mix in with the data fetched
449 # from the OS. This by itself is not considered to be very strong, but it may
450 # help in cases where the system pool is not initialized properly. However, it
451 # is very strongly recommended that the system pool is initialized with enough
452 # entropy either by using hardware assisted random number generator or by
