Latest commit 1894743 Jun 14, 2018

The majority of user data today is stored on massive, server-centric systems that are often vulnerable to data breaches. is a cross-platform app developed to implement a self-sovereign identity system. uses an RSA public-key cryptosystem to share business cards and messages using encrypted json files. Users connect to each other via bluetooth and can be assured that the information shared is genuine and verified, since every user has full control over their data and with whom they choose to share it.

react-native run-android

Attempts to open the app on a connected Android device or emulator. Requires an installation of Android build tools (see React Native docs for detailed setup).
