When you start TorChat for the first time you see a list of available chat partners. The list is empty except for the identity of the logged in user.

New contacts are added with a right-click and the selection of Add Contact from the context menu.

Setup is a bit more complicated considering that the unique ID of each user needs to be added. It is also important to add a display name for easier user identification. That’s different from many other Instant messengers where it is easier to add contacts by importing them.

Online users are indicated with a green icon in front of their username. A double-click on an icon opens a chat window to talk to the selected contact.

TorChat supports file transfers which can be started with a right-click on the chat window. It currently does not offer “gimmicks” lick chat smileys for instance.

But what are the advantages of using TorChat? The use of TOR ensures that nobody can monitor the Internet traffic to find out with whom you are chatting and sharing files and where they and you are located in the world. TorChat initiates a “fully encrypted peer-to-peer connection” between two Tor clients which means that the traffic is never leaving the TOR network. That’s different from how many people perceive TOR. For web surfing and TOR, it is necessary to leave the network at some time to connect to the destination. With TorChat, that’s not necessary.

TorChat is a portable application for Windows and Linux that can be downloaded directly from the project website at Google Code.

Torchat utilizes the power of the Tor network to create a peer to peer instant messaging system, effectively a secure anonymous and encrypted instant messenger that runs right of the box. The software program is fully portable and can be run from external drives or local hard drives.

One limitation of the current version is that the listening port cannot be changed unless the user is doing it in the source which would mean that it would have to be compiled again. The author promised to add a configuration option to change the listening port of the application in a later version.

Once started the user is greeted with a window similar to the one on the above screenshot with the difference that no other contacts are added obviously. To add users one needs their Torchat ID which is a series of random chars, a nickname to identify the person and a initial message. The easiest way to exchange these would be by email, website, phone or other Instant Messengers. Paranoids will probably exchange them during a real-life meeting.

The author has some plans for his Instant Messenger. He plans multi-user chats, file transfers, customization options and block lists among other things. One to look out for.
