The Role Based Auth .NET Sample is an sample ASP.NET Web API to help understand how role based authentication can be implemented via JWTs in a .NET 8 application. It utilizes an InMemory database using Entity Framework Core for storing user data and the Argon2 hashing algorithm for encrypting passwords.

This sample was created for Aditya Oberai's talk at .NET Conf 2023.

The API has 1 controller:

• AuthController: Contains the login, registration, and test APIs

The AuthController contains the login, registration, and test APIs we are using to get and try the JWT token authentication.

• POST /auth/login

  • Returns the JWT token along with the user information from the database after the user enters their email and password.

  • Post Http Request Link: https://<YOUR-DOMAIN:PORT>/auth/login

  • Request Body Example:

    {
        "userName": "adityaoberai1",
        "password": "test1234"
    }

  • Response Example:

    {
        "userName": "adityaoberai1",
        "name": "Aditya Oberai",
        "roles": [
            "User",
            "Admin"
        ],
        "isActive": true,
        "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1bmlxdWVfbmFtZSI6ImFkaXR5YW9iZXJhaTEiLCJnaXZlbl9uYW1lIjoiQWRpdHlhIE9iZXJhaSIsInJvbGUiOlsiVXNlciIsIkFkbWluIl0sIm5iZiI6MTY5OTI3OTQyNywiZXhwIjoxNjk5MjgxMjI3LCJpYXQiOjE2OTkyNzk0MjcsImlzcyI6IlRlc3RJc3N1ZXIiLCJhdWQiOiJUZXN0QXVkaWVuY2UifQ.d9bAAqm1iHWmf7klIBWA2tFf2Pkvzfkee1lBvhv0_Ag",

    }

    Note: Token returned will be different from the example

• POST /auth/register

  • Adds the user's details to the database and returns the JWT token along with the user information after the user enters their information.

  • Post Http Request Link: https://<YOUR-DOMAIN:PORT>/auth/register

  • Request Body Example:

    {
        "name": "Aditya Oberai",
        "userName": "adityaoberai1",
        "password": "test1234",
        "role": [
            "User", 
            "Admin"
        ]
    }

  • Response Example:

    {
        "userName": "adityaoberai1",
        "name": "Aditya Oberai",
        "roles": [
            "User",
            "Admin"
        ],
        "isActive": false,
        "token": null,
        "password": "$argon2id$v=19$m=65536,t=3,p=1$gFcsc5mOvzCclGj+o2CqeQ$TBCPrC6HW1+kCmtCc7vai9JJv3SOgPQK/mMjiJf7X8M"
    }

• GET /auth/test

  • Returns claims from the JWT sent as the Bearer token in the Authorization header with User role.

  • Get Http Request Link: https://<YOUR-DOMAIN:PORT>/auth/usertest

  • Request Header Example:

    Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1bmlxdWVfbmFtZSI6ImFkaXR5YTEiLCJnaXZlbl9uYW1lIjoiQWRpdHlhIE9iZXJhaSIsInJvbGUiOiJVc2VyIiwibmJmIjoxNjk5Mjc5NjA2LCJleHAiOjE2OTkyODE0MDYsImlhdCI6MTY5OTI3OTYwNiwiaXNzIjoiVGVzdElzc3VlciIsImF1ZCI6IlRlc3RBdWRpZW5jZSJ9.JpCzjncNg14Ptx1c1fRt4fZmUAIcuBSowL_WoVYZo6s
