Qavren.Auth (.NET)

Thin ASP.NET Core JWT bearer wiring for Qavren (Keycloak) realms. One call configures authority, JWKS validation, and realm-role mapping by convention. No custom cryptography.

Install

dotnet add package Qavren.Auth

Use

builder.Services.AddQavrenAuth("squarelog");
// or: builder.Services.AddQavrenAuth("squarelog", o => o.BaseUrl = "http://localhost:8080");

var app = builder.Build();
app.UseAuthentication();
app.UseAuthorization();

app.MapGet("/me", (ClaimsPrincipal u) => new { sub = u.FindFirstValue("sub") })
   .RequireAuthorization();

app.MapGet("/admin", () => "secret")
   .RequireAuthorization(p => p.RequireRole("admin"));

realm_access.roles is flattened into standard role claims, so [Authorize(Roles = "admin")], RequireRole("admin"), and User.IsInRole("admin") all work without knowing Keycloak's claim shape.

Convention (shared by all Qavren SDKs)

  • Base URL: QavrenAuthOptions.BaseUrl, else QAVREN_AUTH_URL, else https://auth.qavrensolutions.com. HTTPS metadata is required unless the base is http://localhost / http://127.0.0.1 (local dev).
  • Authority / issuer: {base}/realms/{realm}.
  • Claims consumed: sub (name claim), email, realm_access.roles.
  • Audience is NOT validated — Keycloak defaults aud to account. Trust rests on RS256 signature (realm JWKS) + issuer + lifetime.
  • Fail closed: any invalid token, or an unreachable JWKS, yields a 401 challenge — missing role yields 403.

Realm isolation

A token minted for squarelog is signed by squarelog's key and issued by .../realms/squarelog. An app wired with AddQavrenAuth("recharacter") validates a different issuer against a different JWKS, so the squarelog token is rejected — proven by TokenFromAnotherRealm_IsRejected.
