It may surprise you but Signal is to blame for WhatsApp’s encryption

Signal is to blame for WhatsApp's encryption

Before it was accused of violating people’s privacy, Signal made a deal with Facebook to add WhatsApp’s encryption. Thanks to them, you can now talk to each other without fear.

One of the best messaging apps for people who care about their privacy is Signal. It is a favorite in this section because it has features like end-to-end encryption, the ability to use PINs, and the ability to change the way faces look in photos. Few people knew that Signal is also the company behind the encryption protocol used by WhatsApp.

Even though Facebook’s privacy scandals have led to public fights between the two companies, they did work together for a short time a few years ago. The company that makes Signal, Open Whisper Systems, said in 2014 that WhatsApp would use its encryption protocol. TextSecure would be added to all messages, voice memos, files, and calls by the company.

WhatsApp’s encryption

Signal announced after a year that all iOS, Android, Windows Phone, Nokia, and BlackBerry WhatsApp applications have end-to-end encryption. WhatsApp assured its users that no one outside the chat could read or listen to their messages and calls.

Remember that conversation warning? Thanks to their partnership.

WhatsApp’s encryption

Signal thought about all possible ways for third parties to read conversations, including the possibility that they could use an old version of the client to get plain text messages. Users of WhatsApp can check to see if the chats they have with their contacts are encrypted. The client uses QR codes that can be scanned or a string of numbers that both the sender and the receiver have.

The Signal vs. WhatsApp feud

Brian Acton, who helped start WhatsApp and is now in charge of Signal

Edward Snowden, an NSA analyst who leaked secret information, helped spread the word about Signal. Snowden suggested that people use TextSecure and RedPhone, which are two Open Whisper apps that were later combined into what we now call Signal. Later, groups like Black Lives Matter and Elon Musk himself came up with the idea for the app.

Signal is free source and operated by hacktivist Moxie Marlinspike and WhatsApp co-founder Brian Acton. In February 2018, Facebook donated $50 million to the project with the purpose of democratizing private communication.

Even though WhatsApp and Signal worked together for almost a decade, they have had public fights. One of the most recent was in 2021, when the second showed how Facebook shows ads to people who are interested in them. Signal planned a campaign to show how much information Meta gets from its users.

Mark Zuckerberg didn’t like the idea and said that Signal was telling lies to get attention. Facebook wouldn’t let Signal show the ads, so it temporarily took Signal’s account offline. Even though users couldn’t see the ads, they did a lot of damage and made a fool of Facebook.

Even though Signal doesn’t have as many users as WhatsApp, it and Telegram are still options for people who want to keep their conversations private. When you see the “end-to-end encryption” message in one of your WhatsApp chats, remember that Signal engineers made this feature possible.
