Off The Grid

Off The Grid (OTG)
--------------------------
OTG let's you send sensitive information or urgent information to someone else regardless of having internet or not.
This is done by using a encrypted Bluetooth connection between two devices.
OTG works between 10 to 100 meters depending on the terrain of the area the user is at.
Off The Grid targets people exploring wilderness, hikers, and anyone who wants to send messages with guaranteed security.

How does one use OTG?
- Simply open the app, because a username a hit the OTG button.
- One user chooses to host the OTG chat
- The other user chooses to join the OTG chat and selects the device hosting it.
- A Diffie-Hellman key exchange takes place
- The key is then converted into a shared AES Key
- The two users now have a secure Off The Grid messaging channel open

Information
- All chats are displayed in one screen for maximum simplicity
- Users can wipe the messages off their phone at any time with no trace of them taking place
