MrWho

Kotlin Spring Boot Demo Client

This demo proves MrWhoOidc works great outside of .NET by using Kotlin + Spring Boot.

It supports:

• Interactive login (OIDC Authorization Code + PKCE) via Spring Security
• OBO (token exchange): exchange the signed-in user’s access token for an API token
• M2M (client_credentials): acquire a machine token and call the same API endpoint

Run with the demo stack

From the repo root:

docker compose -f MrWho/demos/docker-compose.yml up -d --build

Then open:

• App: http://localhost:5090
• Token comparison page: http://localhost:5090/token-comparison (requires sign-in)

Notes

• The demo stack uses https://mrwho.local:9443 as the issuer.
• The container imports the demo TLS cert (MrWhoOidc/certs/aspnetapp.pfx) into the JVM truststore so Spring can fetch discovery/JWKS over HTTPS.
