Installation

yarn add veramo-plugin-did-config

Usage

Programmatically

This plugin relies on the availability of other veramo plugins installed on the same agent.

The minimum Veramo configuration for using this library requires the following dependencies:

yarn add @veramo/core @veramo/message-handler @veramo/did-resolver @veramo/credential-w3c @veramo/did-jwt @veramo/data-store did-resolver

When initializing your Veramo agent message handler, the order of the handlers matters. JwtMessageHandler should be first.

import { createAgent } from "@veramo/core";
import {
  DIDConfigurationPlugin,
  IWellKnownDidConfigurationPlugin,
} from "veramo-plugin-did-config";
import { MessageHandler } from "@veramo/message-handler";
import { CredentialIssuer, W3cMessageHandler } from "@veramo/credential-w3c";
import { DIDResolverPlugin, UniversalResolver } from "@veramo/did-resolver";
import { JwtMessageHandler } from "@veramo/did-jwt";
import { Resolver, DIDResolver } from "did-resolver";

const uniresolver = new UniversalResolver({
  url: "https://uniresolver.io/1.0/identifiers/",
}) as DIDResolver;

export const agent = createAgent<IWellKnownDidConfigurationPlugin>({
  plugins: [
    new DIDConfigurationPlugin(),
    new MessageHandler({
      messageHandlers: [new JwtMessageHandler(), new W3cMessageHandler()],
    }),
    new DIDResolverPlugin({
      resolver: new Resolver({
        key: uniresolver,
        web: uniresolver,
        ethr: uniresolver,
        ion: uniresolver,
        elem: uniresolver,
        //...
      }),
    }),
    new CredentialIssuer(),
  ],
});

Since we are asserting the agent to have a type of IWellKnownDidConfigurationPlugin we can access the plugin methods directly. The verifyWellKnownDidConfiguration method will return an object with the provided domain, list of DIDs associated with it, the JSON DID Configuration which was verified, and a boolean for validity.

const { domain, dids, didConfiguration, valid } = await agent.verifyWellKnownDidConfiguration({ domain });

Command line usage

Clone the plugin repo on your machine and configure the agent instance by editing the agent.yml file (or, if you’re simply trying it or joining a hackathon, keep the configuration as it is).

  1. Run the following command to execute your agent:
yarn && yarn build && yarn start
  1. Execute the following command to generate a DID:
yarn veramo execute -m identityManagerCreateIdentity -a "{}"
  1. Execute the following command to generate your Well-Known DID configuration file, using the DID created in the previous step and the domain from your company:
yarn veramo execute -m generateDidConfiguration -a "{\"dids\":[\"<did>\"],\"domain\":\"<domain>\"}"
  1. Upload the Well-Known DID Configuration file to the company website and host it under the well-known URI: https://<domain>/.well-known/did-configuration.json

  2. Verify your Well-Known DID Configuration running:

yarn veramo execute -m verifyWellKnownDidConfiguration -a "{\"domain\": \"<domain>\"}"
