WhatsApp, Facebook’s Messenger and Google embedded Signal’s encrypted messaging system into their own apps this year.Įven so, security researchers said they preferred Signal over other messaging apps because it was more thorough in protecting users’ privacy. Signal’s technology sets the standard for other messaging services, with its protocol being an open-source system that other companies can freely use. That means that if a government agency had a wiretapping order for your Signal messages, Open Whisper Systems would not have the key to decipher the messages and would be unable to comply.
Only the person who receives your message holds the key to decrypt and read it. When you initiate a conversation with someone on Signal, you and the recipient exchange so-called cryptographic keys. Signal offers end-to-end encryption, meaning a message is scrambled so that it becomes indecipherable to anyone but its intended recipient when it is sent from your device, and it remains so when it passes through the app’s server and reaches the recipient. “A lot of people are justifiably concerned about that.” How Signal Stands Out “Trump has threatened a lot of people and he’s about to be in control of the most pervasive and least accountable surveillance infrastructure in the world,” Mr. Marlinspike, the surge in downloads reflects anxiety among Americans about the implications of Mr. Trump won the election, according to Moxie Marlinspike, who founded Open Whisper Systems, the nonprofit that developed Signal.

And during my tests, the service had some glitches. It lacks some features of other messaging apps, like the ability to send stickers. “The default recommendation you’ll get from most security researchers for a messaging app is Signal,” said Joseph Bonneau, a postdoctoral researcher at the Applied Crypto Group at Stanford University. What’s more, messages remain encrypted when passing through Signal’s servers, meaning that the app’s creators can’t read them. The chat service retains virtually no information from users, including messages and address books, on its servers. Signal is one of many encrypted messaging services, but it stands out for its uncompromising security and ease of use. Trump, who has chosen Mike Pompeo, who advocates greater surveillance, to lead the Central Intelligence Agency. Many are also watching for how government surveillance may grow under Donald J. That’s because hacks are on the rise - look at how the activist group WikiLeaks posted a trove of emails from Hillary Clinton’s campaign chairman, John D.
All have said that Signal goes above and beyond other chat tools in keeping electronic communications private.Īnd now more than ever, we may need it.
