First Time Using CalyxOS Review
Posted on April 3, 2024
| H. Still
“But how are you planning on using the phone?” he asked me. I paused, a bit confused. “As a replacement for my iPhone. I want to do everything with this phone that I can do with my iPhone, and use it as I normally would.” He took a beat to respond, “Wow, alright. Well let’s give it a shot.”
I would describe myself as tech-curious, but the reality is I am not your typical CalyxOS user.

The future of our fdroid-compatible app repository
Posted on February 24, 2024
| eighthave
Guardian Project has been running its own fdroid-compatible app repository since 2012. Up until now, we worked to ensure that our repository had the same standards of free software as the official F-Droid repository. Therefore, the Guardian Project repository was included in the official F-Droid client app by default. A lot has changed since then, for the better. F-Droid has long since stopped shipping pre-built binaries from any provider. Back in the day, F-Droid shipped some binaries, like Mozilla’s Firefox APKs, and allowed some non-free libraries in apps.

Quick set up guide for Encrypted Client Hello (ECH)
Posted on November 10, 2023
| jochensp
The Encrypted Client Hello (ECH) mechanism draft-spec is a way to plug a few privacy-holes that remain in the Transport Layer Security (TLS) protocol that’s used as the security layer for the web. OpenSSL is a widely used library that provides an implementation of the TLS protocol. The DEfO project has developed an implementation of ECH for OpenSSL, and proof-of-concept implementations of various clients and servers that use OpenSSL, and other TLS libraries, as a demonstration and for interoperability testing.

DEfO - Developing ECH for OpenSSL (round two)
Posted on November 9, 2023
| Stephen Farrell
Encrypted ClientHello (ECH) plugs a privacy-hole in TLS, hiding previously visible details from network observers. The most important being the name of the web-site the client wishes to visit (the Server Name Indication or SNI). This can be a major privacy leak, like when accessing a dissident news source hosted on a Content Delivery Network (CDN). A visible domain name also provides a straightforward method for censors to block websites and internet services.

| Intern Alfred
Our summer intern Alfred just graduated high-school and is preparing to attend a major university to focus on a technical degree. He has a personal interest in privacy and security, and is working with us on a variety of projects this summer as part of a broad, crash-course in all things Guardian Project!
Last week, I worked with three different apps for the iPhone that, when they work together, allow for a secure and private mobile internet experience.

Improving website resilience with LibResilient and IPFS
Posted on June 15, 2023
| uniq
We’re always looking for techniques to make services more resilient to all sorts of issues. That’s why we took special interest in LibResilient and mapped out it’s capabilities. It’s a JavaScript library for decentralized content delivery in web-browsers and markets itself as easy to deploy to any website. We’ve looked at LibResilient primarily in the context of static websites. While it should work with dynamic websites too, that was out of focus for us.

EU should not require sharing unpatched vulnerabilities
Posted on June 11, 2023
| EDRi.org
We, the undersigned organisations, write to express our concern with vulnerability disclosure requirements under the proposed Cyber Resilience Act (CRA). The CRA’s objective to encourage software publishers to patch vulnerabilities and report cyber incidents is salutary. However, the CRA’s mandatory disclosure of unmitigated vulnerabilities will undermine the security of digital products and the individuals who use them.
The CRA would require organisations to disclose software vulnerabilities to government agencies within 24 hours of exploitation (Cyber Resilience Act, Articles 11.

Between 2022 and 2023 Guardian Project, with support from Okthanks and the Tor Project, organized and participated in a total of 12 workshops in Ecuador, Mexico and Brazil with the participation of 161 people. The workshops focused both on the broad topic of “Tor for Smartphones”, while also taking deeper dives into specific topics like virtual private networks VPNs) and anonymous web browsing. Through a variety of methods, we gathered feedback from the participants in each of those sessions.

Day Five of the 116th IETF meeting in Yokohama Japan. For the rundown on Day Four, see my daily report.
With a lot of focus on privacy with respect to Internet protocols, novel new cryptography schemes are an important requirement for new protocol designs. For example, Privacy Preserving Measurement is relying on new cryptography to support distributed aggregation of a wide range of measurements in the advertising domain as well as application telemetry.

The IETF is getting serious about interoperability among messaging services (this might have had something to do with it). The charter for the Messaging Layer Security Working Group (MLS) specifically excluded interoperability, though the group organized a draft that addressed the basic concepts that would allow MLS-compatible systems to federate. In early 2023, a new Working Group - More Instant Messaging Interoperability (MIMI) - was chartered to expand on the MLS federation work.

The long-running work on MASQUE - proxying all network-layer datatypes over QUIC (HTTP/3) - is nearing completion, with the specification for Proxying IP in HTTP in IESG review. With these components in place, the original MASQUE concept - a non-probable relay for client traffic providing privacy guarantees - has been revived, now defined within the new framework and leveraging HTTP Unprompted Authentication.

The OHAI Working Group has submitted the core draft of Oblivious HTTP Application Intermediation to the RFC Editor for editorial finalization and publication. OHAI is designed to support transational uses of the HTTP protocol that seek IP address privacy (by means of a relay pair, one associated with the client and one associated with the target resource).

This post begins a daily blog, live from the 116th meeting of the Internet Engineering Task Force in Yokohama, Japan, March 25-31, 2023. We’re focusing on standards activities of importance to the Internet Freedom community.
Since IETF114 (report), the Privacy Preserving Measurement Working Group has been deliberating over two distinct proposals offering very different technical methodologies for undertaking measurement activities while respecting user privacy. STAR offers an approach called k-anonymity - reporting a measurement value only if k or more parties are also reporting the same value.

Arti, next-gen Tor on mobile
Posted on March 4, 2023

For software projects with recurring bugs, efficiency or security issues there’s a joke making the rounds in the software industry: “Let’s re-write it in Rust!” It’s a fairly new low-level programming language with the declared goal to help developers avoid entire classes of bugs, security issues and other pitfalls. Re-writing software is very time consuming, so it rarely happens, especially when just one more fix will keep a project up and running.

Steps towards trusted VPNs

VPNs have become quite popular in recent years for a number of reasons, and more and more they are being touted as a privacy tool. The question is whether using a VPN does improve privacy. It is clear that VPNs are quite useful for getting access to things on the internet when direct connections are blocked. VPN providers include a number of tactics in both their client apps and server infrastructure to ensure that their users are able to make a connection.

Scanning apps, off the record

Smart phones have brought us so many wonderful capabilities. They let people around the world access vast realms of information. They let app developers solve problems large and small in a way most relevent to their local context. They are personal computers for the world. They also have given surveillance capitalism an unprecedented reach into everyone’s lives. Repressive governments use them in ways that the East German Stasi secret police could only have dreamed of.

The Search for Ethical Apps: Let's start with governments
Posted on September 1, 2022
| Hans-Christoph Steiner
Governments across the world are moving services to mobile apps. The vast majority of these apps are only available in the Google Play store or in the Apple App store. Installing apps from these services requires users to agree to their terms of service. This means governments require their citizens to sign opaque and privacy invading contracts with foreign Big Tech in order to use digital services. This feeds ever more into Big Tech data control, filtering, and information bubbles.
