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.

sq user testing results

By Lars on August 28, 2022

I did some user testing of sq with five volunteers. This blog post is a report of what I learned. Good news: everyone did get all the tasks done successfully and within the one hour I had allocated, with plenty of time left over. Of course, there were a few things that could be improved.

Plan for user testing of sq

By Lars on August 4, 2022

I will do some informal user testing of sq. In short, I will watch volunteers use sq to achieve specific tasks that I give them. The goal of this is to find out pain points when using sq: what is easy and straightforward; what is difficult to understand; what is difficult to do. The testing will cover the sq command line tool and its built-in help, but not any other manuals or materials.
