The Democratic National Committee has apparently embraced the smartphone app that ex-National Security Agency contractor Edward Snowden says he uses every day, according to Vanity Fair’s Nick Bilton.

It’s called Signal, an app designed for secure text messages and phone calls, and it’s easy to see why it would be beneficial.

In June, at least two different hacker groups tied to the Russian government were expelled from the servers of the DNC, where they had burrowed in and downloaded reams of data for roughly a year. Much of that data, in the form of leaked internal emails, were later posted to the website WikiLeaks.

A month before the hacking revelations, Bilton reported, DNC staffers were told they should use this “Snowden-approved” app whenever they were mentioning Donald Trump, especially if their message was disparaging.

Signal is an incredibly easy-to-use app for iPhone and Android that allows both encrypted text and voice communications. Founded by Moxie Marlinspike in 2014, it requires no sign-up, registration, or exchange of information between parties. You just download the app, install it on your phone, and call whoever you want to talk to, using regular phone number.

It features end-to-end encryption — meaning there is no middleman able to intercept — and it just works. “Even if we wanted to, we can’t hand your information over to anyone,” Marlinspike told TechCrunch.
