Generate WiFI QR codes on Ubuntu

New versions of Android and iPhone can connect to wifi just by scanning QR code in the default camera application. I think this is pretty cool. Creating these QR code is a bit cumbersome in my experience. You have to generate it manually which requires remembering the password in the first place.

To make it a bit easier I wanted to just type the wifi name and get the QR code, which is what this project does!

Warning

This is very hacky:

it directly reads the .ini files in /etc/NetworkManager/system-connections and . This is almost certainly a bad way of getting wifi passwords.
It needs sudo access.
It's my first Go utility and it was written mostly for fun and learning.
I don't plan to maintain it whatsoever :)

Example

Installation:

$ go get github.com/Visgean/qr-wifi

(Plus you need to make sure that you have a $GO_PATH/bin in your .bashrc path.)

Usage

Show QR codes for all networks:

$  sudo $GOPATH/bin/qr-wifi

Filter networks by name:

$  sudo $GOPATH/bin/qr-wifi cafe1

Hacky way to get rid of sudo:

I only use it on personal, encrypted computer to which no-one else has access to, so I don't care much for security on this level. Therefore I am happy to use this permission to avoid typing sudo:

$ sudo chown root:root `which qr-wifi`
$ sudo chmod 4775 `which qr-wifi`

Kudos:

This project is based on @fumiyas/qrc.
