The Android lock pattern works as follows: nine pads are arranged in the form of a grid numbered from 1 to 9. Whene the user define his password (lock pattern), Android encode the password in Hexadecimal and encrypte it in SHA-1 then store it in: /android/data/system/gesture.key`.

Android lock pattern finder open the gesture.key file and read the encrypted password then generate SHA-1 hashes using permutations of numbers (0 to 8) untill it found the same hash stored in gesture.key.
The numbers used to find this hash will incremented by 1 to display the right password.
