WIFI_WEP_KEY0–3
These are the secret keys that are programmed into each device on a WLAN to use WEP
(Wired Equivalent Privacy). Each of these keys must be entered correctly in order for
WEP to work.
Each of the four WEP keys is an array of either 5 or 13
binary bytes
, not an ASCII string.
Set
len
to 5 for a 40-bit key, or 13 for a 104-bit key. Marketing literature sometimes refers
to these as 64-bit or 128-bit keys. The 24 “extra” bits that are included in the marketing
description serve as a cryptographic initialization vector.
WIFI_AUTH
The authentication option is used to configure different types of authentication that the
Wi-Fi device supports. There are three types of authentication that are supported—open-
system authentication (
WIFICONF_AUTH_OPEN_SYS
), shared-key authentication
(
WIFICONF_AUTH_SHARED_KEY
), or both (
WIFICONF_AUTH_ALL
). The most important
consideration is to use the same type of authentication as the access point you are planning
on using; hence,
WIFICONF_AUTH_ALL
is the most flexible value.
WIFI_WPA_PSK_PASSPHRASE
This WPA option is only available if the
WIFI_USE_WPA
macro has been defined.
The command sets a key for the previously specified
WIFI_SSID
value. The key is com-
puted as a hash of the passphrase and the target SSID, which could potentially take a long
time to run. See the
PASSPHRASE.C
sample program for alternatives.
If your program (or TCP configuration) defines
_WIFI_PSK_PASSPHRASE
to a quoted
string, then that string will be used automatically as a pass phrase, unless
_WIFI_PSK_HEX
is also defined (see the following command description).
WIFI_WPA_PSK_HEX
This WPA option is only available if the
WIFI_USE_WPA
macro has been defined.
The command sets a hexadecimal
WPA PSK
master key. The string must be exactly 64
hexadecimal digits (using the characters 0–9 and a–f or A–F). This is interpreted as a byte
string and parsed into the appropriate 32-byte binary key.
If your program (or TCP configuration) defines
_WIFI_PSK_HEX
to a quoted string of 64
hex digits, then that string will be used automatically as the PSK master key.
