It is as simple as using a SMS app.
- Send your public information to your friend using whatever app you want
- ask them to send their own information
- add their devices
- start sending messages ; nobody except you and your recipient can read them :)
The app is using strong encryption technic.
The roadmap include :
- ability to rename local recipient (better to call a device "Dave" or "Steve" ... your friends name ;) )
- ability to use PGP/GPG ; currently it is using RSA+signature(RSA)
- ability to use bluetooth connectivity to create proxy connection (students, etc...)
- encrypted DAO
The whole app is open source :
- main source tree
- cyptographic library
