I have an application that generates the /etc/network/interfaces file for connecting to the users wifi network. This application uses wpa_passphrase to generate the psk, which is then copied into the interfaces file.
is exposing the psk in /etc/network/interfaces a security risk?
For example: (the passphrase in this case is asdfASDF123)
auto wlan0 iface wlan0 inet dhcp wpa-ssid homeWifi wpa-psk f4a4c36b738fd7340d0959e307dd76f05a9c5da5801a5f1ba08a5b2fafdfc067
