Sequoia is a very young project. Currently, we do not actively seek code contributions, but you can try it out, have a look, and tell us what you think. We’d love to get in contact with you.

Get Sequoia

Sequoia is maintained in a Git repository. To clone it, do:

% git clone

Build Sequoia

To build Sequoia, you need a Rust toolchain. To install it on a Debian system, do:

# apt install git rustc cargo clang make pkg-config nettle-dev libssl-dev capnproto libsqlite3-dev

As of this writing, this works fine on Debian 10 (Buster). You can use Debian 9 (Stretch), but you need to pull rustc, cargo, and nettle-dev from testing.

Then to build it, do:

% cargo build --all

Among other things, this builds the sq binary, a simple frontend that can be used to experiment with Sequoia and OpenPGP. The documentation for this tool is here

To run all the tests, do:

% cargo test --all
