Hagrid

Hagrid is a verifying OpenPGP key server. When a new key is uploaded a token is sent to each user ID via email. This token can be used to verify the user ID. Keys can be queried by their verified user IDs (exact match) and their primary keys fingerprint. Keys can be deleted by clicking a link send to all user IDs.

Quick Start

Building Hagrid required a working Rust nightly toolchain. The key server uses the filesystem to store keys, user IDs and tokens. To run it, supply the absolute path to where you want the database to live and the absolute path to the template directory.

cp Rocket.toml.dist Rocket.toml
cargo run --bin hagrid

This will spawn a web server listening on port 8080.

Hagrid uses sendmail for mailing, so you also need a working local mailer setup.

Usage

You can find instructions and API documentation at the running instance at https://keys.openpgp.org.

Building

Building Hagrid requires a working nightly Rust toolchain. The easiest way to get the toolchain is to download rustup. After rustup is installed, get the nightly compiler and tools:

cd hagrid
rustup override set nightly

The web server can now be built with the cargo command:

cargo build --release

After compilation a binary is placed in target/release/ called hagrid. The binary is linked statically and can be copied everywhere.

cp target/release/hagrid /usr/local/bin

To deploy the key server copy all directories under dist/ to a writable location, and create a suitable configuration file.

mkdir /var/lib/hagrid
cp -R dist/* /var/lib/hagrid
cp Rocket.toml.dist /var/lib/hagrid/Rocket.toml
$EDITOR /var/lib/hagrid/Rocket.toml
/usr/bin/env --chdir=/var/lib/hagrid ROCKET_ENV=production hagrid

This will spawn the server in foreground. The server will put all keys and runtime data under the base folder (/var/lib/hagrid in the above example).

Reverse Proxy

Hagrid is designed to defer lookups to reverse proxy server like Nginx and Apache. The key database is a set of 3 directories with static files in them. The directory structure reflects Hagrids URL scheme. This way, lookups via /vks/v1/by-finingerprint, /vks/v1/by-keyid, and /vks/v1/by-email can be handled by (multiple) simple HTTP server(s). A sample configuration for Nginx is part of the repository (nginx.conf).
