EUDI Verifier Endpoint

Important! Before you proceed, please read the EUDI Wallet Reference Implementation project description

License

Table of contents

Overview

This is a Web application (Backend Restful service) that acts as a Verifier/RP trusted end-point. This backend service is accompanied by a Web UI application implemented here.

See section Run all verifier components together on how to boot both applications together.

Application exposes two APIs

The Verifier API, supports two operations:

  • Initialize Transaction, where Verifier may define whether it wants to request a SIOP or OpenID4VP or combined request
  • Get Wallet response, where Verifier receives depending on the request an id_token, vp_token, or an error

An Open API v3 specification of these operations is available here.

The Wallet API, provides the following main operations

Please note that

  • Both APIs need to be exposed over HTTPS.
  • Verifier API needs to be protected to allow only authorized access.

Both of those concerns have not been tackled by the current version of the application, since in its current version is merely a development tool, rather a production application.

Disclaimer

The released software is a initial development release version:

  • The initial development release is an early endeavor reflecting the efforts of a short timeboxed period, and by no means can be considered as the final product.
  • The initial development release may be changed substantially over time, might introduce new features but also may change or remove existing ones, potentially breaking compatibility with your existing code.
  • The initial development release is limited in functional scope.
  • The initial development release may contain errors or design flaws and other problems that could cause system or other failures and data loss.
  • The initial development release has reduced security, privacy, availability, and reliability standards relative to future releases. This could make the software slower, less reliable, or more vulnerable to attacks than mature software.
  • The initial development release is not yet comprehensively documented.
  • Users of the software must perform sufficient engineering and additional testing in order to properly evaluate their application and determine whether any of the open-sourced components is suitable for use in that application.
  • We strongly recommend to not put this version of the software into production use.
  • Only the latest version of the software will be supported

How to build and run

To start the service locally you can execute

./gradlew bootRun

To build a local docker image of the service execute

./gradlew bootBuildImage

Run all verifier components together

To start both verifier UI and verifier backend services together a docker compose file has been implemented that can be found here Running the command below will start the following service:

  • verifier: The Verifier/RP trusted end-point
  • verifier-ui: The Verifier's UI application
  • haproxy: A reverse proxy for SSL termination

To start the docker compose environment

# From project root directory 
cd docker
docker-compose up -d

To stop the docker compose environment

# From project root directory 
cd docker
docker-compose down

The 'verifier' service can be configured by setting its configuration properties described here by setting them as environment variables of the service in docker-compose.yaml

Example:

  verifier:
    image: ghcr.io/eu-digital-identity-wallet/eudi-srv-web-verifier-endpoint-23220-4-kt:latest
    container_name: verifier-backend
    ports:
      - "8080:8080"
    environment:
      VERIFIER_PUBLICURL: "https://10.240.174.10"
      VERIFIER_RESPONSE_MODE: "DirectPost"
      VERIFIER_JAR_SIGNING_KEY_KEYSTORE: file:///keystore.jks

Mount external keystore to be used with Authorization Request signing

When property VERIFIER_JAR_SIGNING_KEY is set to LoadFromKeystore the service can be configured (as described here) to read from a keystore the certificate used for signing authorization requests. To provide an external keystore mount it to the path designated by the value of property VERIFIER_JAR_SIGNING_KEY_KEYSTORE.

Example:

  verifier:
    image: ghcr.io/eu-digital-identity-wallet/eudi-srv-web-verifier-endpoint-23220-4-kt:latest
    container_name: verifier-backend
    ports:
      - "8080:8080"
    environment:
      VERIFIER_PUBLICURL: "https://10.240.174.10"
      VERIFIER_RESPONSE_MODE: "DirectPost"
      VERIFIER_JAR_SIGNING_KEY_KEYSTORE: file:///certs/keystore.jks
    volumes:
      - <PATH OF KEYSTORE IN HOST MACHINE>/keystore.jks:/certs/keystore.jks

Endpoints

Some Context around the verifier's endpoints:

A dominant concept around the interactions between a wallet and the verifier is that of a Transaction. A Transaction is initiated by a higher order application requesting the presentation of some credential from a wallet holder.
A Transaction comprises several aspects around the interactions between a wallet and the verifier:

  • The authorization request sent to the wallet (by value or by reference)
  • The response of the wallet to that authorization request
  • The log of events that occurred throughout the whole process

transaction_id is the identifier assigned to a Transaction (result of calling the initialization endpoint) and it is used in the VerifierApi related endpoints.

An Authorization Request is an element of a Transaction and has to do with the specifics of what is requested from the wallet to present.
Its identifier is embedded in the request payload sent to the wallet as the state claim. This state is then posted back from the wallet to verifier, along with its response, and this is the way the initial authorization request is associated with the wallet's response. This identifier is used in the WalletApi related endpoints.

Initialize Transaction endpoint

An endpoint to control the content of the authorization request that will be prepared from the verifier backend service. Payload of this request is a json object with the following acceptable attributes:

  • type: The type of the response to the authorization request. Allowed values are one of: id_token, vp_token or vp_token id_token.
  • id_token_type: In case type is id_token controls the type of id_token that will be requested from wallet. Allowed values are one of subject_signed_id_token or attester_signed_id_token.
  • presentation_definition: A json object that depicting the presentation definition to be included in the OpenId4VP authorization request in case type is 'vp_token'.
  • nonce: Nonce value to be included in the OpenId4VP authorization request.
  • response_mode: Controls the response_mode attribute of the OpenId4VP authorization request. Allowed values are one of direct_post or direct_post.jwt.
  • jar_mode: Controls the way the generated authorization request will be passed. If 'by_value' the request will be passed inline to the wallet upon request, if by_reference a request_uri url will be returned.
  • presentation_definition_mode: Controls how the presentation definition will be embedded in the request. If 'by_value' it will be embedded inline, if by_reference a presentation_definition_uri url will be embedded in the request.
  • wallet_response_redirect_uri_template: If provided will be used to construct the response to wallet, when it posts its response to the authorization request.

Usage:

curl -X POST -H "Content-type: application/json" -d '{
