layman -a flow && emerge gajim-omemo

Install the current stable version via the Gajim PluginManager. You need Gajim version 0.16.5. If your package manager does not provide an up to date version you can install it from the official Mercurial repository. DO NOT USE gajim 0.16.4 it contains a vulnerability, which is fixed in 0.16.5.

hg clone https://hg.gajim.org/gajim
cd gajim
hg update gajim-0.16.5 --clean

NOTE: You have to install python-axolotl via pip. Depending on your setup you might want to use pip2 as Gajim is using python2.7. If you are using the official repository, do not forget to install the nbxmpp dependency via pip or you package manager.

Enable OMEMO Multi-End Message and Object Encryption in the Plugin-Manager. Before exchanging encrypted messages with a contact you have to hit the Get Device Keys button. (Repeat that if you or your contact get new devices.)

Currently the plugin has no user interface for confirming the own and foreign device keys. It uses trust on first use. This will be added in near future.

To see OMEMO related debug output start Gajim with the parameter -l gajim.plugin_system.omemo=DEBUG.

This repository contains the current development version. If you want to contribute clone the git repository into your Gajim's plugin directory.

mkdir ~/.local/share/gajim/plugins -p
cd ~/.local/share/gajim/plugins
git clone https://github.com/omemo/gajim-omemo
