Cracks Android Screenlock Gesture Pattern using Dictionary Attack

Description

A Java tool to crack the Gesture Screenlock pattern of an Android Phone. Android's pattern lock contains a SHA1 hash of the pattern in a gesture.key file in /data/system folder in the internal memory of the android. It has been tested on Android API Level 15 and up, but should work with lower versions as well. As long as you extract the gesture.key file this tool will work

The key is a SHA1 hash of the sequence of bytes for the gesture pattern. The hash is unsalted and hence is easier to crack. The code uses the dictionary which you can download from the link below:-
