Isotoxin Portable

While instant messengers have been around for years - if not decades - there haven’t been a lot of applications that also provide the means to chat securely, without the fear of communications being intercepted. Nonetheless, if you’re looking for this type of software, you might have found what you need in Isotoxin, a multiprotocol secure messenger for Microsoft’s Windows operating system.

Aside from being a secure messenger providing access to file transfers, audio/video calls and encryption across multiple profiles, Isotoxin also includes a few additional perks that some users might really enjoy, like skinnable and multilingual UI, emoticons, avatars, spell checking and auto-update options.

Unfortunately, Isotoxin’s user interface isn’t as impressive as its feature set. It uses the now classic layout with contacts on the left and messages on the right, but the overall look will probably still feel dated for most experienced users.

Although the developer doesn't provide any documentation for the app, getting started is pretty easy, since Isotoxin works out of the box with no special requirements and after joining a network and adding a contact you'll be good to go. Please keep in mind in that in order to add a contact, you'll require that person's public ID - which is a long string of letters and numbers - so be mindful of how you acquire, copy and store this information.

As far as networks are concerned, you can either use a TOX/XMPP connection or a LAN connection. While testing the program, we've experienced some connectivity issues with the latter, but most people will probably only be accessing TOX connections, which seem to work pretty much flawlessly. However, we do hope to see support added for more protocols in the future.

In spite of some minor glitches we've encountered, Isotoxin provided us exactly what it promised: an easy-to-use platform for secure conversations. If you're only interested in a small, accessible and easy to set up messenger for secure calls and messages, you should give Isotoxin a try.
