Off the grid

Thu, 21 Mar 2013 07:14:52 +0000

Off the Grid is effectively a password manager that will help you create different passwords for different websites. Passwords are generated by simply typing in text - the program will use a Latin square (of Sudoku fame) to scan for the password using a specific pattern. The generated Latin square (grid) can be printed out and kept safe so that passwords can be retrieved without a device.

This application is a tribute to GRC's work on password generation using Latin squares: https://www.grc.com/OffTheGrid.htm

OTG (Off the Grid) is particularly useful for sharing passwords. You can simply generate a grid and then scan in the QR code on each persons device; they will then all be able to retrieve the password for "example" by simply typing in "example".
This password sharing could be useful for couples/colleagues with various shared accounts or
IT departments that need to access the same servers with the same password.

The following permissions are used:

android.permission.CAMERA - this is to capture the QR codes for previous grids.
android.permission.INTERNET - this is used to collecting analytics on usage of the application. android.permission.WRITE_EXTERNAL_STORAGE - this is used to temporarily write an encrypted zip file to so it can be emailed.
android.permission.WAKE_LOCK - this is used to keep the screen on while the password is displayed.

There is no master password, so it is advised that you also have a remote wipe tool and lock code for your device.

Warning: this app should NOT be used if your device has been rooted. Why? - Off the Grid relies on being sandboxed by Android; when you root your device other applications may be able to read inside the sandbox created for it.

Recent changes:
Latest update includes additional features for usability: wake lock so the screen stays on while password is displayed and a "speak" button that will read out the password using the phonetic alphabet.

Ask Brian

Tue, 06 Dec 2011 23:02:41 +0000

This is a joke application based on a friend at work - ask Brian any yes/no question. The answers are canned, similar to a magic 8-ball.
