This protocol allows you to connect to a WiFi network using a 8-digit pin number that usually is predefined in the router, the problem is that the pin of many routers from different companies is known or its known how to calculate it. This app makes use of these pins to try the connection and check if the network is vulnerable. Implements several know algorithms for pin generation and some default pins. Also calculates the default key for some routers and allows you to view WiFi passwords you have stored on the device.The use is very simple, when scanning networks around us, will appear networks with a red cross, these are "safe" networks, they have disabled the WPS protocol and default password is unknown.
Which appear with a question mark have enabled the WPS protocol but the pin is unknown, in this case the app lets you try out the most common.
Finally those with a green tick are vulnerable (in principle), they have the WPS protocol enabled and the pin to connect to the network is known. It may also be that the router has turned off WPS but the password is known, in this case also appear green and you can connect with the key.
To connect with pin need be ROOT user in less than 5.0 (Lollipop) versions. The advantage of being ROOT is that if the pin connection is successful we will show the network password, if not we will connect to the network but can not show it. Each feature will be enabled or disabled depending on the situation of each terminal.
NOTICE: Not all networks are vulnerable and that the network appear as such does not guarantee 100% that it is, several companies have updated the firmware of their routers to correct the fault.
