Authagonal.Protocol

Embeddable OIDC / OAuth 2.0 protocol surface extracted from Authagonal.Server.

Provides /connect/authorize, /connect/token, /connect/userinfo, /connect/par (RFC 9126 Pushed Authorization Requests), /.well-known/openid-configuration, and JWKS endpoints plus the token minting pipeline — nothing else. No user store, no SAML, no admin UI, no login pages.

Plug in your own identity via IOidcSubjectResolver and storage via IClientStore / IGrantStore / IScopeStore / ISigningKeyStore. Use this when you need to expose OIDC from an app that already has its own identity (e.g. share-link grants, service-to-service auth).

Quick start

dotnet add package Authagonal.Protocol

builder.Services.AddAuthagonalProtocol(opts =>
{
    opts.AuthenticationScheme = "Cookies"; // or your custom scheme
    opts.Clients.Add(new OidcClientDescriptor
    {
        ClientId = "my-rp",
        RedirectUris = { "https://rp.example.com/callback" },
        AllowedScopes = { "openid", "profile", "email" },
    });
});

builder.Services.AddScoped<IOidcSubjectResolver, MySubjectResolver>();
builder.Services.AddSingleton<IClientStore, MyClientStore>();
// ... IGrantStore, IScopeStore, ISigningKeyStore, ITenantContext

app.MapAuthagonalProtocolEndpoints();

Federation passthrough

OidcSubject.FederationClaims carries per-session claims received from an upstream IdP through to issued tokens, gated by the same scope-driven UserClaims whitelist as CustomAttributes. Federation values win on key collision and survive refresh rotations distinct from the per-user record.
