By default raspi-config adds an unencrypted WiFi password to the wpa_supplicant.conf file.
To remove it do the following:
# get root
sudo su -
# change to the wpa_supplicant dir
cd /etc/wpa_supplicant
# append a hashed Wifi password block
wpa_passphrase "YOURSSID" "YourWifiPassword" >> /etc/wpa_supplicant/wpa_supplicant.conf
Once you have done the above your /etc/wpa_supplicant/wps_supplicant.conf will look similar to this:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=AU
network={
ssid="YOURWIFISSID"
psk="YOURWIFIPASSWORD"
}
network={
ssid="YOURWIFISSID"
#psk="YOURWIFIPASSWORD"
psk=444ed0f3a0a84d62d54827847318ffd227affed4b29c7f5406eec43037c33027
}
You now need to remove the duplicated network block and any references to your unencrypted WiFi password so it looks like this:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=AU
network={
ssid="YOURWIFISSID"
psk=444ed0f3a0a84d62d54827847318ffd227affed4b29c7f5406eec43037c33027
}
