Use Aspire to implement and deploy the BFF security architecture
This blog demonstrates how to use Aspire to set up a solution for developing and deploying an ASP.NET Core web application with Auth0 as the identity provider and a downstream API. The application uses Angular for the frontend and is secured using a Backend-for-Frontend (BFF) architecture. Code: https://github.com/damienbod/Auth0BffDpopApi Blogs in this series Target setup In […]
Implement BFF using Auth0, Angular and ASP.NET Core
This post should how to implement a web application which needs secure access and secure identities. The application uses Angular as the UI tech, ASP.NET Core as the backend tech and a backend for frontend security architecture using OpenID Connect, OAuth and Auth0 as the identity provider. Code: https://github.com/damienbod/Auth0BffDpopApi Blogs in this series Target setup […]
Implement SAML as an external provider in an ASP.NET Core Identity application using Duende as an OIDC server
This article shows how to implement a SAML federation from an ASP.NET Core Identity application using Sustainsys.Saml2.AspNetCore2. Entra ID is used to implement the SAML authentication and the users can authenticate from the tenant. Code: https://github.com/damienbod/DuendeEntraSaml Setup Three components are used to implement this demo, a web application that authenticates using OpenID Connect, an ASP.NET […]
Add application security to the swiyu generic management verifier APIs using OAuth
The article looks at implementing security using OAuth for the swiyu Public Beta Trust Infrastructure generic containers. The container provides endpoint for OpenID verification and the management APIs. The OpenID endpoints are publicly accessible using a reverse proxy, the management APIs can only be accessed in the network and using an access token for app […]
Isolate the swiyu Public Beta management APIs using YARP
This post looks at hardening the security for the swiyu public beta infrastructure. The generic containers provide both management APIs and wallet APIs which support the OpenID for Verifiable Presentations 1.0 specification. The management APIs require both network protection and application security. This post looks at implementing the network isolation. Code: https://github.com/swiss-ssi-group/swiyu-passkeys-idp-loi-loa Blogs in this […]
Use client assertions in ASP.NET Core using OpenID Connect, OAuth DPoP and OAuth PAR
This post looks at implement client assertions in an ASP.NET Core application OpenID Connect client using OAuth Demonstrating Proof of Possession (DPoP) and OAuth Pushed Authorization Requests (PAR). Code: https://github.com/swiss-ssi-group/swiyu-passkeys-idp-loi-loa Blogs in this series: Setup An ASP.NET code application is setup to authentication using OpenID Connect and OAuth PAR. The web application is an OIDC […]
Implementing Level of Identification (LoI) with ASP.NET Core Identity and Duende
This article explores how to implement Level of Identification (LOI) in an ASP.NET Core application. The solution uses Duende IdentityServer as the OpenID Connect provider and ASP.NET Core Identity for user management. Identity verification is performed using the Swiyu Public Beta infrastructure. Any OpenID Connect client can consume the loi claim together with the loa […]
Implementing Level of Authentication (LoA) with ASP.NET Core Identity and Duende
This post shows how to implement an application which requires a user to authenticate using passkeys. The identity provider returns three claims to prove the authentication level (loa), the identity level, (loi) and the amr claim showing the used authentication method. Code: https://github.com/swiss-ssi-group/swiyu-passkeys-idp-loi-loa Blogs in this series: The amr claim and the loa claim returns […]
Implement forgot your password using swiyu, ASP.NET Core Identity and Aspire
This post show to implement a “Forgot your password” flow using the Swiss Digital identity and trust infrastructure, (swiyu) in an ASP.NET Core web application using ASP.NET Core Identity and Duende IdentityServer. The generic containers from swiyu are used to integrate the Swiss E-ID and the OpenID for Verifiable Presentations standards. .NET Aspire is used […]
Implement a secure MCP server using OAuth and Entra ID
The article shows how to implement a secure model context protocol (MCP) server using OAuth and Entra ID. The MCP server is implemented using ASP.NET Core and uses Microsoft Entra ID to secure the API. An ASP.NET Core application using Azure OpenAI and semantic kernel is used to implement the MCP client for the agent […]
