I want to integrate jwt token in my spring service layer.I am passing a json object which should contain a token and I want to do authentication with that. How to do that . Thanks in advance
I have found out a solution for that . Instead of using spring-security-jwt usecom.nimbusdsnimbus-jose-jwt3.9And I am able to do the token authentication with this now.

Im trying to make an .NET 5 Web Api works with Jwt Bearer token. I want some operations to be secured by using a token that comes from another issuer. The token would be generated by MS Azure AD. The application will read the token from the request header, validate it and extract the user's roles for more validations. The app shoudn't be the issuer of the token.
Is this possible? I tried so many ways to make this works without success. I setup Swagger to use OpenId Connect with Microsoft Azure and then the bearer is used to call the secured operations but always got errors. Now I don't understand how Dotnet Core Authencation and Authorization works.
Thanks in advance!
That will definitely work OK but requires an understanding of the science:
AZURE AD TOKENS
I would first look at the JWT in an online viewer. There is a known issue with the default setup where you get JWT access tokens that cannot be validated. See Step 3 of my blog post for details.
UNDERSTAND PRINCIPLES
Validating a JWT involves the general steps in this blog post. Once you understand this it will hopefully unblock you.
C# JWT ACCESS TOKEN VALIDATION IN APIs
The Microsoft framework often hides the required logic, which doesn't always help, and the option I prefer is to validate JWTs via a library.
Aim to understand how to use the JwtSecurityTokenHandler class to validate a JWT manually, eg in a console app. Maybe borrow some ideas from this C# code of mine.
C# AUTHORIZATION
Once JWT validation works, the next step is to use the details in the ClaimsPrincipal to determine whether to allow access to data. I would get on top of the JWT validation first though.
I have tried the sample app of Quarkus and JWT Security Sample App
How can I implement JWT refresh token in Quarkus Framework?
You have to options here, which are basically the same, you have to invoke keycloak through the rest api in order to get your refresh token. You can do that by using a rest-client, like in here or an adapter, this are your options with the jwt integration.
If you instead use a different dependency like the oidc client you will be able to create new tokens and have more options, check this guide.
Thanks
Question
I got a problem with understanding some basic thing about auth0, probably someone can help me out.
In the tutorial SPA + API one of the first lines in the TDLR is this:
Both the SPA and the API must be configured in the Auth0 Dashboard
I dont understand why I need to configure the API on Auth0. My code seems to work so can anyone help me understand if I do something wrong or what the advantages are if I actually add a custom API in my dashboard?
Setup
SPA (React)
Auth0
REST API (ktor)
What I do
Created a SPA on Auth0
Login on my SPA through Auth0 to get a JWT (google token)
Sending the JWT as authentication bearer in my calls to the REST API
REST API verifies the JWT token with a JWK provider using the Auth0 url mydomain.eu.auth0.com/.well-known/jwks.json.
Authentication seems to work
Great question, I am assuming that your authentication request includes audience parameter which represents your custom API(Rest API)right now. In oauth2 terms, it is called Resource Server. Each resource server can have many permissions which you include in the scope when initiating the authentication request. Let's step back and talk about the token format. Auth0 issues token in two formats:
Opaque strings: When not using a custom API
JSON Web Tokens (JWTs): When using a custom API
https://auth0.com/docs/tokens/reference/access-token/access-token-formats#how-does-all-this-affect-the-token-format-
As explained above link, the token format depends on the audience (Custom API) parameter. Therefore, when the authentication request includes audience, auth0 issues JWT token with all necessary permission. Then, you need to validate the JWT token in your API server before returning the resources to your front end client.
It should make sense why you need to create custom API in auth0 and define permissions. If you do not create custom API in auth0, there is no way to know what kind of permission you need in the token which will generate an error(invalid audience specified)
I have a grails 3 application where authentication is done by Siteminder. After the user is authenticated we should be able to generate a JWT token and using that other rest apis call be protected.
I have used RequestHeaderAuthenticationFilter to authenticate the request header. Can anyone help in integrating JWT token in this scenario.
Thanks is advance
I achieved it by using a custom token generator which is called after the request header authentication and saved the token in http response header. Created a custom rest token validation filter to validate the token in API calls
I'm using a service with REST api, which provides me an authentication token as the response for the sign in POST request. Where is it better (and secure) to store? This token should be added to each request after that.
Use Keychain Services to store passwords and tokens.
Use this https://github.com/granoff/Lockbox . Simple way without knowing the apis
