Tox Chat is an open source application that features end-to-end encryption and relies on a P2P network in order to transmit messages. It serves users on a wide variety of platforms, including Android, iOS, MacOS, Windows and Linux. It is important to note that Tox, the platform on which Tox Chat is built, is not a single closed or defined application. Rather, it is a collection of projects that are centered on the toxcore project. As a result, there are a number of clients that users can employ in order to communicate using Tox Chat.

Features offered by Tox Chat

Users on Tox Chat have a direct connection to each other that is distributed through a P2P network which allows them to send each other files, video/voice chat, join chatrooms with strangers and friends, and messages their friends. Tox Chat users enjoy a lot of the same functionalities that VPN users do as traffic over the Tox network is cloaked using authenticated encryption as well as perfect forward secrecy.

The primary purpose of Tox clients is to offer users a variety of anonymized and secure features for communication. Even though all Tox Chat clients support messaging, different mobile and desktop clients offer users varying levels of other features; including video/voice calling, group messaging, typing indicators, conferencing, file sharing, message read-receipts, desktop streaming, and profile encryption.

You can implement additional features regarding which client you use, provided the core protocol supports them. Otherwise, the client is responsible for features that are not supported by the core networking system. Developers of Tox Chat are encouraged to stick to the Tox Client Standard so as to maintain compatibility across clients and uphold the best practices for security.

Using Tox Chat with a VPN

You can use a VPN add another layer of security to your Tox Chat communications. The combination of the Tox Chat protocol and the VPN makes it impossible for anyone to see the content of your online traffic even if they intercepted your signal. As a result, you can evade some of the most common threats faced by people who chat online.

Some of these online threats include:

  • Crash messages. Opening these messages typically cause the messaging app to crash. They’re usually 2KB to 7MB and once opened, you may be forced to reboot the device for it to function normally. When sent to a group, these messages can have the same effect, causing the devices of all members who open the group chat to crash.
  • This is the most common type of online threat. In this case, a user may inadvertently click on a malicious link that redirects them to a site infested by malware. This may provide a backdoor into your device through which it can be infected by malware.

When looking for VPN services to use together with Tox Chat, give preference to well-established providers that employ a powerful encryption standard, offer a variety of security protocols and come with additional security features such as DNS leak protection and a built-in kill switch.
