Sometimes people dive into Signal’s code looking for domain names, and then they send us screenshots asking if they should be concerned: We reply with a short explanation that lays out why there’s nothing wrong, but we understand the confusion. Nobody would be excited about getting a grade like this on a homework assignment – and you’d have to stay after class and ask the teacher what the hell a “

Signal exists to provide people everywhere with a tool for real private communication. That’s our only goal, and we take it very seriously. We’re structured as a nonprofit to ensure that market forces can never put profit or expediency over the safety of those who rely on us. Our work also resonates beyond the Signal app. The Signal Protocol has become the foundation for end-to-end encryption tech

We are excited to announce a significant advancement in the security of the Signal Protocol: the introduction of the Sparse Post Quantum Ratchet (SPQR). This new ratchet enhances the Signal Protocol’s resilience against future quantum computing threats while maintaining our existing security guarantees of forward secrecy and post-compromise security.

Signal now offers a feature called “automatic key verification” which complements the existing safety number system. Signal is always end-to-end encrypted, and automatic key verification provides an additional, streamlined way to confirm that there’s no unexpected party between you and the other “end” of an end-to-end encrypted session.

Winter Break Of Code Day Eighteen Late this afternoon I took a break from working to surf. The sun was setting and a cool breeze was picking up as grey clouds billowed behind the mountains along Hanalei Bay. I had spent most of the day wrangling content, markup, and CSS, and the Pacific was calling. There was still plenty of work to be done, but balance is important, and my mind needed to reset. S

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 someon

After immersing myself for years and years in the world of finance (specifically, options market making and algorithmic trading), there was no escaping this mantra of “no risk, no reward.” Most of the time, my (trading) style was fairly risk-averse. I knew how to find the signals of opportunities among the daily noise to reap small rewards. Fortunately, I also learned how to think about the outlie

Long before we knew that it would be called Signal, we knew what we wanted it to be. Instead of teaching the rest of the world cryptography, we wanted to see if we could develop cryptography that worked for the rest of the world. At the time, the industry consensus was largely that encryption and cryptography would remain unusable, but we started Signal with the idea that private communication cou

A few months ago we completed the process of unifying all of our apps across Android, iOS, and the Desktop under the name ‘Signal.’ This simplified the language around our apps and eliminated a lot of confusion. Now we’re doing the same thing “inside” our apps by renaming Axolotl to Signal Protocol. Axolotl has been the name of the cryptographic protocol that our apps use for end-to-end encryption

Not only can Cellebrite not break Signal encryption, but Cellebrite never even claimed to be able to.

The tech industry–its products, conceptual frameworks, linguistic conventions, and cultural norms–is largely centered in the US (and, increasingly, China. But we’re focused here on the US, where Signal is based). This is not because the US has better programmers or more visionary entrepreneurs, but due primarily to historical material conditions. For example, early investments in networked computa
