Ever wanted to create a cool QR code for your guests? But never wanted to type in your WiFi credentials into a form that submits them to a remote webserver to render the QR code? QiFi for the rescue! It will render the code in your browser, on your machine, so the WiFi stays as secure as it was before (read the code if you do not trust text on the internet :-))!
If you use the Save-button to store a code, this is still secure, as the data is stored in HTML5 localStorage and is never transmitted to the server (in contrast to cookie-based solutions).
Don't trust your browser either? Just pipe the string
WIFI:S:<SSID>;T:<WPA|WEP|>;P:<password>;;
through the QR code generator of your choice after reading the documentation.

Every other QR scanner out there should be able to scan the code too, but probably won't interpret it as intended. If your scanner supports WiFi QR codes, please send me a mail!
