Traditionally, asynchronous messaging systems such as email have relied on protocols like PGP or S/MIME for cryptographic security. These protocols work the way most people are familiar with: one who wishes to receive encrypted email advertises a public key, and those wishing to send encrypted email to that person encrypt their outgoing message with that public key.

Winter Break Of Code, Day Fifteen The 1988 film They Live is one of the last great masterpieces to come out of the Hollywood left. In the film, a drifter named John Nada discovers a box of sunglasses that, when worn, allows the wearer to really see the world around him. For instance, when wearing the glasses, simple advertisements for consumer products are revealed as something other than what they appear. Read more...

Last week, we received the following email from Amazon: From: [redacted], [redacted] <[redacted]@amazon.com> Subject: Notification of potential account suspension regarding AWS Service Terms Moxie, Yesterday AWS became aware of your GitHub and Hacker News/ycombinator posts describing how Signal plans to make its traffic look like traffic from another site, (popularly known as “domain fronting”) by using a domain owned by Amazon -- Souq.com. You do not have permission from Amazon to use Souq.com for any purpose. Any use of Souq.com or any other domain to masquerade as another entity without express permission of the domain owner is in clear violation of the AWS Service Terms (Amazon CloudFront, Sec. 2.1: “You must own or have all necessary rights to use any domain name or SSL certificate that you use in conjunction with Amazon CloudFront”). It is also a violation of our Acceptable Use Policy by falsifying the origin of traffic and the unauthorized use of a domain. We are happy for you to use AWS Services, but you must comply with our Service Terms. We will immediately suspend your use of CloudFront if you use third party domains without their permission to masquerade as that third party. Thank you, [redacted] General Manager, Amazon CloudFront Read more...

Companies like Facebook aren’t building technology for you, they’re building technology for your data. They collect everything they can from FB, Instagram, and WhatsApp in order to sell visibility into people and their lives. This isn’t exactly a secret, but the full picture is hazy to most – dimly concealed within complex, opaquely-rendered systems and fine print designed to be scrolled past. The way most of the internet works today would be considered intolerable if translated into comprehensible real world analogs, but it endures because it is invisible. Read more...

Winter Break of Code, Day Two By all rights, I should not be here. My application was last-minute to say the least, and little more than a casual note that I’d be down to reprise my role from SBoC as web hacker for whispersystems.org. Maybe it was because of my work in the previous months on tweaking the site layout to be responsive, or because @bcrypt (who is infinitely more qualified) was too dedicated to her work at the EFF to take the time off, or because my birthday happened to fall on this week, but for one reason or another, the universe smiled, and here I am.

Spring Break Of Code, Day Four The main sound on top of the ocean is the click clack of laptop keys, and the jangle of test calls and SMSes. A neighbor stopped by to comment that we must be the next Facebook, the next Google; working instead of surfing made sense in his mind only in the land of money at the end of the tunnel. He loaned us his stand up paddle boards, surely expecting a return on investment 10 fold down the line when we exited into the sunset. A journalist visiting Open Whisper Systems’ Spring Break of Code commented that she expected more philosophy, politics, and conversation. After all this group is composed of people who are not only technologists, but also open source evangelists, activists, and humanists. Lilia went over some of the why, but practically anyone could see we were concentrating on the how, and in the frenzied silence it was clear that a common philosophy was assumed and what bound us here was the challenges in the technology to power that philosophy.

My cell phone used to be a black and white Nokia until a couple of weeks ago when I decided to enter in the smartphone world. Now that there are more mobile devices connected to the internet than computers, I think it’s time for me as well to discover the possibilities of this technology. During this few weeks I’ve been playing with my new toy, checking how to secure it, and seeing what free software is around to use cryptography on it. Read more...

Winter Break of Code, Day Seven Spring Break of Code 2013 I cut open my foot and hand while surfing; both wounds easily warranted stitches. Winter Break of Code 2014 I banged the top of my foot surfing over some coral; the cuts were sealed within minutes.

As the world stands today, the future of transaction privacy does not look great. The existing landscape is dominated by traditional credit companies, who over the past decade have been steadily pushing their networks for increased access to user data. They (and their data customers) are on a track to getting SKU level data of every purchase everyone makes everywhere. There are other contenders, such as regional online payments networks (like Venmo in the US), but the data story there is similar. This is not a future we are particularly excited about. At Signal, we want to help build a different kind of tech – where software is built for you rather than for your data – so these are trends that we watch warily. Read more...

Signal released end-to-end encrypted group calls a year ago, and since then we’ve scaled from support for 5 participants all the way to 40. There is no off the shelf software that would allow us to support calls of that size while ensuring that all communication is end-to-end encrypted, so we built our own open source Signal Calling Service to do the job. This post will describe how it works in more detail. Read more...

RedPhone is our mobile app for end-to-end encrypted voice calls. When we talk about RedPhone, we tend to emphasize the cryptography, and how using it can help keep your communications safe. What we don’t talk about as much is the VoIP application underneath all of that, which it turns out was actually the hard part. When we were developing RedPhone, we discovered that the cryptographic aspects of it were relatively straightforward. What we didn’t anticipate was how difficult the mechanics of delivering high-quality, low-latency, and highly available voice communication would be. This describes the basic strategy we developed for the network side of low-latency and highly available calls. Read more...

Signal’s upcoming beta releases will also introduce the option to transfer your messages and media when you link your primary Signal device to a new Desktop or iPad. Instead of starting fresh, and having only new messages show up, you can choose to bring your chats and your last 45 days of media with you. Or, you can choose not to. Read more...
