DIDKit can be installed as a package via cargo, manually from source, or in containerized form.

Cargo install#

  1. To install the DIDKit command line program on GNU/Linux, MacOS, or Windows+WSL, first install cargo.
  2. Install build-essential or equivalent tools if they aren't already installed.
  3. Then simply run cargo install for the given target package: didkit-cli | didkit-http.
    For example, for DIDKit CLI, run:
cargo install didkit-cli

This will add the binary didkit to your Cargo installation (typically ~/.cargo/bin), which can be added to your system's PATH for ease of use.


DIDKit is written in Rust. To get Rust, you can use Rustup.

We do not depend on any Rust nightly features, so our installation instructions assume stable versions; be sure to switch the installation defaults to nightly if the calling application or forked source-code does depend on them.

Spruce's ssi library must be cloned alongside the didkit repository in a parallel directory between downloading didkit and building it.

mkdir didkit
git clone && cd didkit
git clone ../ssi --recurse-submodules

Build DIDKit using Cargo, from root directory of DIDKit project:

cargo build

This will give you the DIDKit CLI and HTTP server executables located at target/debug/didkit and target/debug/didkit-http, respectively. You can also build and install DIDKit's components separately. Building the FFI libraries will require additional dependencies. See the corresponding readmes linked below for more info.


Both the CLI and HTTP server are containerised and available under|http).

The image is private for now, so a Personal Access Token is required. Once created you can login like so:

$ docker login -u USERNAME --password-stdin

You can use the images like CLIs:

$ docker run --help
$ docker run --init -p 8080 --port 8080

Note: You can pass JWKs either by sharing a volume with docker run --volume, or by passing the JWK directly with docker run -e JWK=$MY_JWK or docker run didkit-http --jwk $MY_JWK.

Build Images#

The Dockerfiles rely on having ssi in the root of didkit (a symbolic link will not work, unfortunately).

Then the images can be built with:

$ docker build -f Dockerfile-cli . -t didkit-cli
$ docker build -f Dockerfile-http . -t didkit-http

And to use them, replace|http):latest with didkit-(cli|http).

Building Interfaces#

While many of the DIDKit interfaces can be installed as libraries via each language's dedicated package manager, they can also be built manually. For instructions, see the "Installation" section of each interface's dedicated page in the section to the left.
