I am looking at building a network scanner that will tell the user what type of security is implemented on the network that they are connected too, for example they are using WPA, the application would tell the user this and tell them how insecure it is. I was looking to see if anyone had any ideas, or if anyone had done anything similar that they could help me? Any help would be appreciated, Thanks Chris.
Have a look at the documentation here:
