428 | # wpa_supplicant depends on strong random number generation being available | |
429 | # from the operating system. os_get_random() function is used to fetch random | |
430 | # data when needed, e.g., for key generation. On Linux and BSD systems, this | |
431 | # works by reading /dev/urandom. It should be noted that the OS entropy pool | |
432 | # needs to be properly initialized before wpa_supplicant is started. This is | |
433 | # important especially on embedded devices that do not have a hardware random | |
434 | # number generator and may by default start up with minimal entropy available | |
435 | # for random number generation. | |
436 | # | |
437 | # As a safety net, wpa_supplicant is by default trying to internally collect | |
438 | # additional entropy for generating random data to mix in with the data fetched | |
439 | # from the OS. This by itself is not considered to be very strong, but it may | |
440 | # help in cases where the system pool is not initialized properly. However, it | |
441 | # is very strongly recommended that the system pool is initialized with enough | |
38e24575 | 442 | # entropy either by using hardware assisted random number generator or by |
bbb921da JM |
443 | # storing state over device reboots. |
444 | # | |

445 | # wpa_supplicant can be configured to maintain its own entropy store over |
446 | # restarts to enhance random number generation. This is not perfect, but it is | |
447 | # much more secure than using the same sequence of random numbers after every | |
448 | # reboot. This can be enabled with -e<entropy file> command line option. The | |
449 | # specified file needs to be readable and writable by wpa_supplicant. | |
450 | # | |
451 | # If the os_get_random() is known to provide strong random data (e.g., on | |
bbb921da JM |
452 | # Linux/BSD, the board in question is known to have reliable source of random |
453 | # data from /dev/urandom), the internal wpa_supplicant random pool can be | |
454 | # disabled. This will save some in binary size and CPU use. However, this | |
455 | # should only be considered for builds that are known to be used on devices | |
456 | # that meet the requirements described above. | |
