coyim - a safe and secure chat client
CoyIM is a new client for the XMPP protocol. It is built upon https://github.com/agl/xmpp-client and https://github.com/twstrike/otr3. It adds a graphical user interface and tries to be safe and secure by default. Our ambition is that it should be possible for even the most high-risk people on the planet to safely use CoyIM, without having to make any configuration changes.
To do this, we enable OTR by default, we default to use Tor and we will use the Tor Onion Service for a server if we know it, and also to use TLS and TLS certificates to verify the connection - no configuration necessary. The implementation is written in the Go language, to avoid many common types of vulnerabilities that come from using unsafe languages.
Security warning
CoyIM is currently under active development. There have been no security audits of the code, and you should currently not use this for anything sensitive.
Installation instructions
GUI version
The GUI version requires GTK+ >= 3.6.16, which installation depends on your OS:
Ubuntu:
sudo apt-get install gtk+3.0 libgtk-3-dev
Mac:
brew install gtk+3
Then install coyim:
export GTK_VERSION=$(pkg-config --modversion gtk+-3.0 | tr . _ | cut -d '_' -f 1-2)
go get -u -tags "gtk_${GTK_VERSION}" github.com/twstrike/coyim
CLI version (xmpp-client)
go get -u -tags cli github.com/twstrike/coyim
