A lot people have been talking about the signal app. Well here is what you need to know about this new emerging application.
The Signal app is free to download and was developed to send encrypted text, image, audio, and video messages for individuals and groups. It can also be used for encrypted phone calls between Signal users for mobile users. Here’s a quick look at what this app is all about, and why there’s been a sudden surge of new users for it.
The origins of the Signal app goes back to 2010, when a company called Whisper Systems first launched two Android apps: One was TextSecure, which encrypted text messages, and the other was RedPhone, which did the same for voice calls. In 2011, the company was bought by Twitter and the apps were released as free open-source software.
In 2013, one of the founders of Whisper Systems, Moxie Marlinspike, departed Twitter. He formed another startup, Open Whisper Systems, and continued to develop TextSecure and RedPhone. In 2014, it was announced that the company would merge the two apps into one, with the new name Signal. In 2018, Marlinspike and WhatsApp co-founder Brian Acton formed the non-profit Signal Foundation to continue the development of the app, and to keep it free and open-source software.
