Tox is a peer-to-peer instant messaging and video calling protocol that offers end-to-end encryption. The stated goal of the project is to provide secure yet easily accessible communication for everyone
The Tox Project
"Tox began a few years ago, in the wake of Edward Snowden's leaks regarding NSA spying activity. The idea was to create an instant messaging application that ran without any kind of central servers. The system would be distributed, peer-to-peer, and end-to-end encrypted, with no way to disable any of the encryption features; at the same time, the application would be easily usable by the layperson with no practical knowledge of cryptography or distributed systems. During the Summer of 2013 a small group of developers from all around the globe was formed and began working on a library implementing the Tox protocol. The library provides all of the messaging and encryption facilities, and is completely decoupled from any user-interface; for an end-user to make use of Tox, they need a Tox client. Fast-forward a few years to today, and there exist several independent Tox client projects, and the original Tox core library implementation is continues improving. Tox (both core library and clients) has thousands of users, hundreds of contributors, and the project shows no sign of slowing down.
Tox is a FOSS (Free and Open Source) project. All Tox code is open source and all development occurs in the open. Tox is developed by volunteer developers who spend their after work hours on it, believing in the idea of the project. Tox is not a company or any other legal organization. Currently we don't accept donations as a project, but you are welcome to reach out to developers individually."
"With the rise of government monitoring programs, qTox provides an easy to use application that allows you to connect with friends and family without anyone else listening in. While other big-name services require you to pay for features, qTox is totally free, and comes without advertising."
qTox can be installed via repository or .deb file . In this tutorial we will be installing it by downloading the binary package and running it with gdebi .
Locate the .deb file right click it > Open With > Gdebi Package Installer (if you do not have gdebi installed open a terminal and type sudo apt install gdebi) . This is one of the easiest way to install .deb files hence the package installer pulling all the required dependencies .
Once installed qTox can be accessed from the Dash :
