WiFi networks, despite advancing in security thanks to the work of security researchers, are not a completely secure environment. Unlike wired networks, connecting via WiFi poses an additional security challenge because its signals are accessible to the public.

The different security features like WPA2 they can encrypt traffic, but there are techniques that have the power to alter its security. In the application stores, especially in Google Play, we find Android applications that manage to hack the WiFi connection and that can be used not for profit or criminal purposes, but simply to check the level of security and advance in that aspect.
Somehow, hacking into these networks or unlock WiFi it also serves to access good quality connection and get rid of the vulnerabilities and risks of connecting to free public networks. To learn more about some of these applications that achieve this goal, in this link from the web Your App For they make a review of some tools that help to decrypt keys and check the level of network security. In this article, we have selected the most popular ones and analyzed them below.
Kali Linux NetHunter
Kali Linux is one of the best operating systems for ethical hacking purposes. Developed by Offensive Security, this tool is the first open source Android penetration testing platform.
With this application to hack Android it is essential run the Wifite tool of Kali to move forward with the process. Its interface allows you to unblock all the configuration files of the network you want to access.
Your custom kernel, which supports 802.11 wireless injection, makes Kali Nethunter be one of the most popular tools when it comes to unblocking WiFi networks. However, the work of unlocking is not easy, because it takes a lot of time and insistence.
Router Keygen
With this app you can calculate and decrypt WiFi tracks and browse for free anywhere from Android. As in the previous case, to achieve this, it is not enough to approach a WiFi network, since it is possibly password-protected.
Router Keygen calculate and decrypt WiFi passwords, whether they are WEP or WPA, and thus gain access to the network. With this application, and as long as they do not change the modem password, it is possible to unlock those networks.
If we return to ethical behavior, this app it allows us to connect to our own network in case we have lost access to the connection key. Router Keygen e is compatible with most known routers and its results are very reliable if the password is the one that came as standard on the device.
AndroDumper
AndroDumper is a very recent app that works in a powerful way. It is a WiFi key breaker and it takes advantage of the vulnerability of the WPS protocol. With this application it is possible to decrypt WiFi networks and it differs from other similar ones that what they do is pull dictionary and test if the router key is the one it has by default.
AndroDumper it can be used in Root mode and without Root. For those who do not know how to root the mobile, the procedure is quite simple and it is enough to attend one of the many tutorials that we find on the net.
Wlan Audit
The Wlan Audit Android app it allows you to know the Mac of the Router and the type of security that it has. It works differently than Router Keygen. This app also shows the quality of the network signal, but it does not go much further because it is not valid for decrypting keys or unlocking passwords.
Yes it can be useful for check the connection coverage at the domestic level, know all the corners and make decisions about including access points that strengthen the signal, as repeaters.
WPSApp
A final proposal is WPSAppp, which it works with networks that have WPS encryption. This app highlights its interface for its simplicity, since in it it is shown with a green ticket the possibility of decrypting passwords. If the ticket is red and X-shaped, the result is that the key is not decipherable.
As with AndroDumper it can be used with Root or Without Root. The difference between both methods is that in the first the app shows the key to enter it manually and in the second you access the network directly.
