The latest Signal betas are rolling out today. Inside, you’ll find performance enhancements, a slew of bug fixes, improvements to the mute settings, and if you’re in the United Kingdom, you’ll see support for Signal Payments – a new feature that enables you to send and receive privacy focused payments as easily as sending or receiving a message. This is a beta feature in a beta build, but for those in the United Kingdom living life on the edge, please help us test and give feedback. Read more...

2020 has seen its fair number of challenges and changes. We’ve all adapted to new ways of staying in touch, getting work done, celebrating birthdays and weddings, and even exercising. As more and more of our critical and personal moments move online, we want to continue to provide you with new ways to share and connect privately. Today, we’re launching group calls in Signal with the latest versions of our apps. Group calls are free, private, and end-to-end encrypted — like everything else on Signal. Read more...

At Open Whisper Systems we help develop TextSecure, an encrypted chat application for Android. TextSecure was designed as a general purpose SMS/MMS client which would also automatically encrypt conversations when communicating with other TextSecure users. For those encrypted sessions, TextSecure uses a compact derivative of the well-known OTR protocol. We’re currently in the process of transitioning TextSecure to use a device’s data channel as a transport for communication with other TextSecure users whenever possible. This enables communication with the upcoming TextSecure for iOS, helps users avoid SMS fees, and obscures conversation metadata from telcos. The transition to a new transport is also a good opportunity for us to evaluate and introduce additional cryptographic protocol changes. Below is one cryptographic protocol change we’re thinking of making that we’d welcome feedback on. Read more...

Whether it’s staying in touch with family and friends, planning a party, scheduling an event, getting work done, or organizing for change, group chats are an increasingly important part of Signal. Today we’re releasing a new version of Signal groups that gives you a richer private group experience with group admins, granular permissions, @mentions and more. If you’re excited to try out these features now, you can create a new group to do so. These features will be coming soon to your existing Signal groups in a future update. Signal groups are built on top of the new private group system technology we previewed last year, which gives you a modern group chat experience while keeping your groups private: the Signal service has no access to your group memberships, group titles, group avatars, or group attributes.

Signal is the world’s most widely used truly private messaging app, and our cryptographic technologies provide extra layers of privacy beyond the Signal app itself. Since launching in 2013, the Signal Protocol—our end-to-end encryption technology—has become the de facto standard for private communication, protecting the contents of billions of conversations in WhatsApp, Google Messages, and many others. Signal also continues to invest in research and development in the pursuit of extending communications privacy. This commitment underlies our recent work to add a layer of quantum resistance to the Signal Protocol, and our previous work on metadata protection technologies that help keep personal details like your contact list, group membership, profile name, and other intimate information secure. This singular focus on preserving the ability to communicate privately is one reason that we work in the open, documenting our thinking and making our code open source and open to scrutiny—so you don’t have to take our word for it.

Spring Break Of Code, Day Five I know very well that each and every crisis of modernity is concentrating, concatenating, and seating more deeply into everyday life. I know the struggles of the world’s unseen and unheard are being subsumed – appropriated – under and into the framework of a liberal democracy, leaving those at the periphery still under the yoke of capital. The Right further entrenches itself into political discourse, both in the United States, and (more extremely) abroad (Finland, Greece, … et al.). The Left is no less problematic: reiterating the petty values of social democracy, negotiating the terms of our entrapment within capitalism. Every season, new horrors fall from the clouds and rise from the seas as industrial civilization demonstrates that terraforming can also work in reverse. The world’s genetic library – the most prime commons, if ever one existed – is rapidly contracting via extinction, privatization, and engineering. The colossal failure of ideology in the twentieth century has left the radicals of today no other choice but to see themselves as “post-ideological”. This is a deeply concerning conundrum, as ideology survives in post-ideology, different only to the extent that it is less apparent. Yes, it seems like we are living in end times – an entire era of Apocalypse – made only more insidious by our optimism in its shadow. Read more...

We’ve been working on strategies to improve our current design, and today we’ve published a new private contact discovery service.

Winter Break Of Code Day Eleven Every morning at standup I’d watch the knife spin in slow motion, dread filling my chest and a voice in my head repeating, over and over, “not Slytherin.” (The target of the knife is the author of the next day’s blog post). I wasn’t sure that I could find new ways to marvel at the wonderful absurdity of stepping on a plane and trading reality for this – a chance to work on the world with a group of people that I’ve only admired from afar. I wasn’t sure that I had anything to say that hadn’t already been said by my new friends. Read more...

In the past, if you broke or lost your phone, your Signal message history was gone. This has been a challenge for people whose most important conversations happen on Signal. Think family photos, sweet messages, important documents, or anything else you don’t want to lose forever. This explains why the most common feature request has been backups; a way for people to get Signal messages back even if their phone is lost or damaged. After careful design and development, we are now starting to roll out secure backups, an opt-in feature. This first phase is available in the latest beta release for Android. This will let us further test this feature in a limited setting, before it rolls out to iOS and Desktop in the near future. Read more...

Right now, people around the world are marching and protesting against racism and police brutality, outraged by the most recent police murders of George Floyd and Breonna Taylor. At Signal, we support the people who have gone into the streets to make their voices heard. We believe that something in America needs to change, and even if we don’t know exactly how, we support and trust in the people who are self-organizing around the country to figure it out. Many of the people and groups who are organizing for that change are using Signal to communicate, and we’re working hard to keep up with the increased traffic. We’ve also been working to figure out additional ways we can support everyone in the street right now. One immediate thing seems clear: 2020 is a pretty good year to cover your face. Read more...

Signal Protocol is a modern, open source, strong encryption protocol for asynchronous messaging systems. We use Signal Protocol as the foundation for our own private messaging app, Signal, but also make Signal Protocol libraries available for other applications to use. Our Signal Protocol libraries are open source, licensed GPLv3. We like the GPL for the quality control that it provides. If someone publicly says that they’re using our software, we want to see if they’ve made any modifications, and whether they’re using it correctly. This helps to increase transparency and accountability in deployments of our software, which we feel are important for end-to-end encryption. Read more...

The latest releases of Signal for Android, Desktop, and iOS are rolling out now with the ability to send optional link previews. This feature is built on the same foundation that has powered Signal’s animated GIF search for more than two years and that we have since expanded with additional privacy enhancements. We’re launching link previews with initial support for Imgur, Instagram, Reddit, and YouTube. These are four of the most popular sites on the Internet and their heavy focus on visual content makes them a perfect fit for this feature. We don’t believe that privacy is about austerity, and now Signal users can see what’s behind the URL while sharing this content with their friends. Read more...

Cellebrite makes software to automate physically extracting and indexing data from mobile devices. They exist within the grey – where enterprise branding joins together with the larcenous to be called “digital intelligence.” Their customer list has included authoritarian regimes in Belarus, Russia, Venezuela, and China; death squads in Bangladesh; military juntas in Myanmar; and those seeking to abuse and oppress in Turkey, UAE, and elsewhere. A few months ago, they announced that they added Signal support to their software. Their products have often been linked to the persecution of imprisoned journalists and activists around the world, but less has been written about what their software actually does or how it works. Let’s take a closer look. In particular, their software is often associated with bypassing security, so let’s take some time to examine the security of their own software. Read more...

Winter Break of Code, Day Five Understanding digital privacy under capitalism If commodities could speak, they would say this: our use-value may interest men [sic], but it does not belong to us as objects. What does belong to us as objects, however, is our value. Our own intercourse as commodities proves it. We relate to each other merely as exchange-values. – Marx, Capital: A Critique of Political Economy, Vol 1. Thus spake the commodity Marx saw modernity more acutely than most of his contemporaries, and provided a description of capitalism that remains, in my opinion, quite useful. However, we must be brave enough to attempt to understand his description of the relationship between commodity and value in the context of a world very different from Industrial Revolution-era Europe. That is, one which includes the strange new primordial soup of the internet and capital. Imagine, as Marx expects of us in the passage above, that an “internet” commodity could speak. What would it say? Read more...
