For many a modern-day hero, for some an old-fashioned anarchist and traitor, for all a seasoned computer professional obsessed with encrypted communication services. NSA whistleblower and former CIA employee Edward Snowden is a lot of things to a lot of people, but if you’re as anal as him about keeping your voice calls and texts away from prying ears and eyes, a free mobile app dubbed Signal should put all concerns to bed.
Rolled out to iOS back in March, the private messenger client can now be installed on Android devices as well through Google’s Play Store. Hopefully, law enforcement won’t ban Signal and similar services anytime soon, but to be on the safe side of things, you may want to download it ASAP, and take a gander at the source code.
The open-source project blends together two different apps developed by Open Whisper Systems, TextSecure and RedPhone, the former obviously handling your impenetrable SMS exchanges, and the latter taking care of voice scrambling, including cross-platform, from an Android to an iPhone and vice versa.
If you happened to already use one of the intertwined OWS services, you’ll be urged to either update TextSecure or replace RedPhone with Signal. In both cases, you’re promised “advanced end to end encryption” for universal privacy, safeguarded group chats, instant delivery of messages, and no long-distance charges, regardless of the town or country you’re reaching out to and from.
Alas, Signal Private Messenger isn’t compatible with tablets and desktops yet, although support for “larger screens” is “on the roadmap and will be included in a future release.”
