Signal desktop app with end-to-end encryption now open to all

Open Whisper Systems’ Signal desktop app is now open to all. Launched in December, the private messaging app for desktops was available on an invite-only basis, but now the Desktop Signal beta is now available for all. Signal is a Chrome app that can be linked to a smartphone, allowing to display all incoming and outgoing messages on all connected devices. This free app syncs only with your Android devices for now, but the company reportedly plans to add iOS support too.
