unmessage 0.2.0

Privacy enhanced instant messenger

unMessage

unMessage is a peer-to-peer instant messaging application designed to enhance privacy and anonymity.

Warning

unMessage is alpha software. While every effort has been made to make sure unMessage operates in a secure and bug-free fashion, the code has not been audited. Please do not use unMessage for any activity that your life depends upon.

Features

• Transport makes use of Twisted, Tor Onion Services and txtorcon

• Encryption is performed using the Double Ratchet Algorithm implemented in pyaxo (using PyNaCl)

• Authentication makes use of the Socialist Millionaire Protocol implemented in Cryptully

• Transport metadata is minimized by Tor and application metadata by the unMessage protocol

• User interfaces are created with Tkinter (graphical) and curses (command-line)

Quick Start

Install the following requirements via package manager:

# If using Debian/Ubuntu
$ sudo apt-get install build-essential gcc libffi-dev libopus0 \
  libsodium-dev libssl-dev portaudio19-dev python-dev python-tk

# If using Fedora
$ sudo dnf install gcc libffi-devel libsodium-devel \
  openssl-devel opus portaudio-devel python-devel \
  redhat-rpm-config tkinter

If you have tor installed, make sure its version is at least 0.2.7.1:

$ tor --version

If you must update it or do not have it installed, check the version provided by the package manager:

# If using Debian/Ubuntu
$ apt-cache show tor

# If using Fedora
$ dnf info tor

If the version to be provided is not at least 0.2.7.1, you will have to set up Tor’s package repository. Once you have a repository which can provide an updated tor, install it:

# If using Debian/Ubuntu
$ sudo apt-get install tor

# If using Fedora
$ sudo dnf install tor

Installing

Finally, if you use pip and setuptools (probably installed automatically with pip), you can easily install unMessage with:

$ sudo pip install unmessage

Launch unMessage with any of the commands:

$ unmessage-gui # graphical user interface (GUI)
$ unmessage-cli # command-line interface (CLI)
$ unmessage # last interface used

Updating

If you installed unMessage with pip, you can also use it for updates:

$ sudo pip install --upgrade unmessage

Documentation

You can find installation and usage instructions (for the GUI and the CLI) on the documentation.
