Signal Expands Secure App to Desktop

by Michela Menting | 4Q 2015 | IN-3905

Open Whisper Systems is the firm behind the secure messaging app, Signal, the one recommended by the infamous NSA whistleblower Edward Snowden, for secure conversations, as well as security superstar Bruce Schneier. The mobile app allows for secure messaging and calling, and has been available for iPhone and Android since 2014. The app is free and open-source, having been published by Open Whisper Systems under a GPLv3 license. Essentially, the app is a legacy of the RedPhone and TextSecure apps, which have been around for a few years already. Open Whisper Systems recently announced a desktop version of the Signal app that can sync with the mobile version. Users will have a single identifier for both. Signal Desktop will first be offered as a Chrome app (and later a plug-in) and in time, the firm is planning for broader iOS support, as well. Currently the desktop version is in beta, although at signup, the queue for testing was over 18,000 users long.
