torchat
(Typically launches a GUI application)

TorChat is a peer-to-peer instant messenger utilizing Tor hidden services for anonymous and decentralized communication. It enables users to chat securely without revealing their IP addresses, routing all traffic through the Tor network. Each user is identified by a unique Tor hidden service address (a .onion address). Running TorChat creates a local hidden service, allowing direct, encrypted message exchange with others via their .onion addresses, bypassing central servers. Designed for simplicity and privacy, it was a pioneering effort in anonymous messaging. However, its development has largely ceased, rendering it outdated and potentially insecure for current use. Despite its obsolescence, TorChat holds historical significance as an early and influential example of a truly anonymous messenger application.

TorChat is an unmaintained and outdated project, which may pose significant security risks due to unpatched vulnerabilities. It may not function correctly with modern Tor versions or operating systems without manual adjustments. As a graphical application, its utility from the command line is limited to launching the GUI. It relies entirely on the Tor network; Tor must be running and accessible for TorChat to function.

TorChat functions primarily as a graphical user interface (GUI) application. Executing the command typically launches an interactive window rather than providing command-line output or functionality for scripting.

Successful operation of TorChat requires the Tor daemon to be actively running and accessible on the system. It also depends on a compatible Python runtime environment.

Developed by Bernd Ulmann in 2007, TorChat emerged as one of the first truly anonymous and decentralized instant messengers. Its appeal lay in its serverless design, simplicity, and reliance on Tor hidden services for privacy-preserving communication. Written primarily in Python, TorChat gained a user base among privacy advocates. However, active development largely ceased around 2014-2015, leading to its eventual deprecation. Lack of ongoing maintenance resulted in compatibility issues with newer Tor versions and unaddressed security flaws, making it obsolete. More modern and actively developed alternatives have since superseded it.
