DIDKit

DIDKit provides Verifiable Credential and Decentralized Identifier functionality across different platforms. It was written primarily in Rust due to Rust's expressive type system, memory safety, simple dependency web, and suitability across different platforms including embedded systems. DIDKit embeds the ssi library, which contains the core functionality.

Security Audits

DIDKit has undergone the following security reviews:

We are setting up a process to accept contributions. Please feel free to open issues or PRs in the interim, but we cannot merge external changes until this process is in place.

Install

Manual

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

Spruce's ssi library must be cloned alongside the didkit repository:

$ git clone https://github.com/spruceid/ssi ../ssi --recurse-submodules

Build DIDKit using Cargo:

$ cargo build

That 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.

Container

Both the CLI and HTTP server are containerised and available under ghcr.io/spruceid/didkit-(cli|http).

You can use the images like CLIs:

$ docker run ghcr.io/spruceid/didkit-cli:latest --help
$ docker run --init -p 8080 ghcr.io/spruceid/didkit-http:latest --port 8080

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 ghcr.io/spruceid/didkit-(cli|http):latest with didkit-(cli|http).

Usage

DIDKit can be used in any of the following ways:

CLI - didkit command-line program
HTTP - HTTP server (Rust library and CLI program)
FFI - libraries for C, Java, Android, and Dart/Flutter
