Abblix OIDC Server

Abblix OIDC Server is a robust .NET library that implements the OpenID Connect protocol on the server side. Designed with modular and hexagonal architecture patterns, it provides a compliant, extensible framework for adding OIDC-based authentication and authorization to .NET applications. It supports Dependency Injection using the standard .NET DI container, and uses its own JWT implementation built on .NET cryptographic primitives.

What's New in Version 2.3

🚀 Features

  • Rich Authorization Requests (RFC 9396): fine-grained, transaction-level authorization details across the authorization endpoint, PAR, the token endpoint, CIBA, and the device grant
  • Token Exchange (RFC 8693): impersonation and delegation with multiple subject- and actor-token formats
  • DPoP sender-constrained tokens (RFC 9449): signature-based proof of possession for public clients that cannot use mTLS
  • Certificate-bound access token verification (RFC 8705 §3): resource-server check that a presented token matches the client certificate
  • JARM: signed, optionally encrypted JWT authorization responses
  • JWT-secured token introspection (RFC 9701): signed introspection responses via content negotiation
  • JWE-encrypted request objects (RFC 9101): confidential request parameters in the front channel and by reference
  • Signed authorization server metadata (RFC 8414): opt-in, integrity-protected discovery document

✏️ Improvements

  • Secure-by-default: Implicit Flow is now opt-in, and Dynamic Client Registration requires an Initial Access Token (RFC 7591)
  • Token-class confusion defense via opt-in token-type pinning (RFC 8725), JWS key pinned to its declared algorithm (RFC 7517), enforced HMAC key length (RFC 7518)
  • Authorization-response issuer parameter (RFC 9207) advertised in discovery

Implemented Standards

Abblix OIDC Server implements a comprehensive suite of standards for authorization and security:

OAuth 2.0

JSON Web Token (JWT)

OpenID Connect

Installation

dotnet add package Abblix.OIDC.Server

Note: Most applications should use Abblix.OIDC.Server.MVC which includes this package plus ASP.NET MVC integration with controllers, model binding, and routing.

Package Description
