This utility helps you to easily install root certificates: just copy them in "my_certificates" folder on your (internal) sd card and run the utility.
When you'll add a new WPA-Enterprise network from wireless setting menu, you'll find them "ready to go" ;-)
Your certificates should be in PEM-encoded x509 certificate-file format; other formats could work too, but they are not officially supported.
The application needs INTERNET permission because it uses a local web server to make browser download certificates.
ATTENTION! I'll not take any responsibility for any problems or damages or side effect you may experience using this application: run it at your risk!
