tommyteavee/panickit

a framework for providing trusted connections between panic button apps and other apps that should be triggered by them

PanicKit is a collection of tools for letting panic trigger and panic receiver apps safely and easily connect to each other. The trigger apps are the part that the user will actual engage when in a panic situation. The receiver apps receive the trigger signal from the trigger apps when the user has initiated the panic response. The connections between trigger and receiver can be strictly enforced based on packageName and APK signing key.

An overview of the PanicKit and how to use it is here: https://guardianproject.info/code/panickit

Reproducible Build

To build your own jars from source and recreate the exact same files, bit-for-bit, as the official releases, strip-nondeterminism is required to set the timestamps in the ZIP headers to match the timestamp in the git release tag (e.g. 0.2).

To install it on Debian/jessie, Ubuntu/vivid/15.04 or newer, just do:

sudo apt-get install dh-strip-nondeterminism
