dis-authentication-stub

This project provides an authentication service stub for testing login and authentication processes without relying on dp-identity-api, Florence, or Cognito. The dis-authentication-stub simulates essential login, token renewal, and proxy functionality, allowing local testing for services such as dp-dataset-api when running in "private endpoints enabled" mode.

Getting started

To run the service locally:

• Run make debug to run application on http://localhost:29500

Additional Commands:

• Run make help to see full list of make targets
• Run make prep to decrypt the necessary files to run the service

Dependencies

• No further dependencies other than those defined in go.mod

Endpoints and Functionalities

This stub provides the following endpoints to facilitate testing of authentication workflows:

1. Health Check

   • GET /health: Returns 200 OK to confirm the service is running.

2. Login Simulation

   • GET /florence/login: Displays a form with a list of configured users. Accepts an optional redirect query parameter (default is /florence/collections).

   • POST /florence/login: Processes the form submission, setting the following cookies:

     • access_token: Signed JWT for the selected user.
     • id_token: Signed JWT for the selected user.
     • refresh_token: Random opaque token stored in memory.

3. Token Management

   • DELETE /tokens/self: Logs out the user by removing session entries and expiring the id_token, access_token, and refresh_token cookies.

   • PUT /tokens/self: Reads the refresh_token cookie to renew the access and ID tokens if valid. Returns 400 if missing or 403 if expired.

4. JWT Key Retrieval

   • GET /jwt-keys: Returns a JSON map of public JWT signing keys, matching the format of dp-identity-api.

5. API Reverse Proxy

   • /api/: Proxies requests to APIs and sets the Authorization header with the access_token cookie value.

6. Service Identity Validation

   • GET /identity: Verifies the service token in the Authorization header. Returns the app ID if valid, or 403 Forbidden otherwise.
