Authorization Server using IdentityServer4

Authorization Server using IdentityServer4 4.1.2 on ASP.NET Core 3.1.

This is my attempt at improving my understanding of modern authentication, that is, OpenID Connect & Oauth 2.0 and how these two protocols are implemented in IdentityServer4 4.1.2 on ASP.NET Core 3.1

Prerequisites

• Visual Studio 2019 or greater
• ASP.NET Core 3.1

Getting started

1. Clone the project.
2. Open the solution file AuthorizationServer.sln on Visual Studio.
3. Press F5 to start the build and run the application.

How to manually set Kestrel's HTTPS configuration with a development certificate file

Export ASP.NET Core's development certificate (the one that gets automatically created when you install .NET) to %APPDATA%\ASP.NET\https\AuthorizationServer.pfx (notice the filename is the same as your executing assembly).

dotnet dev-certs https -ep "$Env:APPDATA\ASP.NET\https\AuthorizationServer.pfx" -p '12345'

Add the following setting to your appsettings.json file. The password must match the password used for the exported certificate in the previous step.

"Kestrel": {
    "Certificates": {
        "Development": {
            "Password": "12345"
        }
    }
}
