Secure and Robust

Sequoia focuses on security and robustness in our choice of tools, our development methodology, and feature set.

Easy to Use

A library is only as good as its integration in downstream projects. As such, we made ease of use one of our main goals.

Holistic Approach

Improving the security of OpenPGP users requires more than a new implementation. Therefore, we are taking a holistic approach and are improving the ecosystem.

Testimonials

Sequoia PGP is more than just a reimplementation of an existing tool. The team behind it is rethinking tooling for the broader PGP ecosystem. Their innovative ideas are making PGP easier to use. I can’t wait to see Sequoia PGP be more broadly adopted.

Phil Zimmermann

Creator of PGP
During the last 3 years the PGP ecosystem got un-stuck, largely thanks to the Sequoia project. They put in the gargantuan effort of re-implementing PGP, but also started re-imagining other tools in the ecosystem, with the same common-sense, practical security approach. This is already making a difference for my team, and those whose security we’re responsible for.

Michał "rysiek" Woźniak

Head of Infrastructure and Information Security, OCCRP
Sequoia has fundamentally improved my work on the pEp Engine. I love how fast all the tests run on Sequoia. It’s OBSCENE. With the old PGP implementation it would take nearly 2 minutes to run. With Sequoia, running the whole test suite takes less than 2 seconds. I am… not free from symptoms of ADHD. Running all of the tests on Sequoia means that they’re over before I have time to get distracted. That’s a serious improvement.

Senior Developer, the pEp Engine

Sequoia PGP: Out and About

By Neal on September 4, 2024

Over the past few months, we’ve attended a number of conferences. In addition to hearing from a lot of people who had helpful feedback and fresh ideas, we’ve also held several presentations.

In this post, I summarize our talks, and link to recordings when they are available. I also report on the OpenPGP Email Summit, which is a yearly gathering of some people from the OpenPGP community. (If you are interested in the so-called LibrePGP / OpenPGP schism, read on.)

At the end, I list where you can meet us in person in the near future. (Spoiler: at Datenspuren in Dresden in September, and IETF 121 in Dublin in November.)

UX studies to test and improve sq

By Franzi on June 18, 2024

In a few months, we plan to release version 1.0 of sq, our primary command line interface. With version 1.0, we will commit to a long-term stable API. Ideally, that API will also be usable. Although we’ve put in a lot of time thinking about usability, we want your feedback. To this end, we’re conducting a user study.

Sequoia PGP: Following a Moral Imperative

Karakun AG ★ 2023-11-07

Neal makes a call to action: As developers, we have the moral imperative to explain to our clients that they must not violate human rights, in particular the rights to privacy, security, and freedom of expression. Further, we must resist requests to collect unnecessary data, and we must add end-to-end encryption where possible.

He then presents OpenPGP, and in particular Sequoia PGP, as one possible option that developers should consider to help protect users.
