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

A Look at Two Recent CVEs in Thunderbird's OpenPGP Support

By Neal on May 22, 2021

In a blog post that I published two weeks ago, I wrote that RNP is dangerous, because it is too easy to misuse. I also explained how we avoid those problems in Sequoia. In this blog post, I will lay out how not one, but two CVEs have since come up in Thunderbird that seem to underline that danger.

Hello, OpenPGP CA!

By Neal on May 12, 2021

We are pleased to share that version 0.10.1 of OpenPGP CA has been released! This is also the first version which is available on crates.io.

OpenPGP CA is a tool for administrators to create and manage a decentralized, in-house certification authority. OpenPGP CA makes it possible and easy for an organization to delegate authentication decisions to someone they can rely on, like their system administrator. And, external groups and individuals can use these CAs to authenticate certificates for just that organization using OpenPGP’s scoped trust signatures. OpenPGP CA also helps with key discovery and key updates by managing a Web Key Directory (WKD).
