About this guide

This guide is about sq, the primary command line interface for Sequoia PGP. Here you will find an overview of the most common use cases and commands. There are also chapters about cryptography in general as well as some of Sequoia PGP's underlying concepts.

Very specific examples are only presented occasionally. If you can't find something about a command here, please take a look at its --help output or its man page. This book may not cover the exact version of sq that you are using, so check that when details seem wrong or incomplete, bearing in mind that this book is still under development. It is built from the 'sequoia-pgp/user-documentation' git repository, where changes are made and tracked.
