Wrapper for the Briar Headless REST API

Project description

Briar Wrapper

pipeline status coverage report

A wrapper library for Briar to run on Python platforms. It uses the Briar REST API and therefore requires Java.


The easiest way to install Briar Wrapper is to install the package from pip install briar_wrapper


The documentation of the project can be found at To generate it locally, call tools/


You can also build it yourself by runninng the following command: flit build

Note that you need to have installed flit to do this.


First, install some dependencies:

sudo apt install build-essential devscripts debhelper python3-all flit dh-python

During building the package, we will also run tests:

sudo apt install python3-pytest python3-requests python3-websockets python3-requests-mock python3-pytest-mock

In order to generate the original source package, install flit and use it to build python-briar-wrapper:

flit build

You can now use the archive generated in the dist directory to build the Debian package:

mv dist/briar_wrapper-0.0.3.tar.gz ../python-briar-wrapper_0.0.3.orig.tar.gz
cd ..
tar -zxf python-briar-wrapper_0.0.3.orig.tar.gz
cd briar_wrapper-0.0.3

Now, build the .deb like this:

debuild -us -uc

And install the .deb like this:

sudo dpkg -i ../python3-briar-wrapper_0.0.3-1_all.deb

Design Goals

  • Main platform is GNU/Linux, but should also support (at least) Windows and macOS
  • Analogously, main platform is x86, but should also support (at least) arm


I forgot my password.

In case you forgot your password, there's no other way than to delete your old account and start from scratch. Call rm -rf ~/.briar/ to delete your current account.

How can I transfer a Briar account from my Android device?

By using adb, you can copy the database and keys from a Briar Android installation. Note that your smartphone needs to be rooted for this.

You shouldn't use this technique to clone your Briar account to another device and then use the same account on both devices. If you do this, you open up yourself to many possible threats. See this comment on Briar's issue tracker for more information. Therefore, make sure to delete the old copy of your Briar account after you've transferred it to another device to protect yourself against attacks circumventing forward secrecy.

In case you just want to transfer contacts from one account to another, better use the "contact introduction feature" which is already available on Android devices and which is planned to land in python-briar-wrapper, too.

You can either use the script at tools/ or do it manually:

  1. Start briar-gtk and register a dummy account. This will create the needed directory structure at ~/.briar/. Close the program afterwards.
  2. Enable adb on your smartphone and give it root permissions.
  3. Connect via adb and gain root permissions using adb root.
  4. Copy all important files using adb pull: /data/data/, /data/data/, /data/data/
  5. Replace the respecting files in ~/.briar/db and ~/.briar/key.
