This demo is about another tool that I worked out during an assignment while working with an integration scenario using web services supporting basic authentication.
The problem with basic authentication is that you have to keep username and password stored somewhere in order to generate the authentication token. Since I was integrating the external web services with SharePoint, so I felt to delegate the token generation process to an external tool and consume the Authentication Token directly without keeping username and password to be stored in the code itself.
This token can be used for any web service supporting basic authentication, and this strategy can be merged with other functionalities too in order to generate this token on the fly.

In fact, it is quickly becoming a de facto standard for modern single-page applications and mobile apps. Authentication is the process by which an application confirms user identity. Applications have traditionally persisted identity through session cookies, relying on session IDs stored server-side.
A few major problems caused by this technique:. Token based authentication is stateless. Every single request will require the token. First of all, is necessary create new ASP. NET Core project. I suggest to use ASP. Once the project is successfully created, add the following configurations to your appsettings. The TokenAuthentication section configures some common information about token generation, for example the SectionKey used by token.
To enable Bearer token authentication, import the following Nuget package Microsoft. The Startup. The tokenValidationParamaters object will be used also by Cookie validation.
Unprotect method decript and validate information provided by the input token. In order to initialize the middleware, it is necessary modify the Startup. The tokenProviderOptions defines the options of the token generator. The IdentityResolver is the Task method which will check the identity of users. For demo purposes, the IdentityResolver is implemented by a simple method called GetIdentity. Now is possible call the ConfigureAuth method inside the Startup. All controllers decorated by the attribute [Authorize] are protected by the JWT authentication.

A token is a piece of data that has no meaning or use on its own, but combined with the correct tokenization system, becomes a vital player in securing your application. Token based authentication works by ensuring that each request to a server is accompanied by a signed token which the server verifies for authenticity and only then responds to the request. JWT has gained mass popularity due to its compact size which allows tokens to be easily transmitted via query strings, header attributes and within the body of a POST request.
The header and payload are Base64 encoded, then concatenated by a period, finally the result is algorithmically signed producing a token in the form of header. The header consists of metadata including the type of token and the hashing algorithm used to sign the token.
The payload contains the claims data that the token is encoding. The final result looks like:. Tokens are signed to protect against manipulation, they are not encrypted.

What this means is that a token can be easily decoded and its contents revealed. If we navigate over the jwt. In a real world scenario, a client would make a request to the server and pass the token with the request. The server would attempt to verify the token and, if successful, would continue processing the request.
If the server could not verify the token, the server would send a Unauthorized and a message saying that the request could not be processed as authorization could not be verified.
Token based authentication and JWT are widely supported. Add the following code on the playground:. To check the contents our token, we can decode it at jwt.
The simplest way to do this is to use an app like Postman which simplifies API endpoint testing. When the call is made the jwtCheck middleware will examine the request, ensure it has the Authorization header in the correct format, extract the token, verify it and if verified process the rest of the request. We used just the default settings to showcase the capabilities of JWT but you can learn much more via the docs.

I am trying to implement session management in my REST service. I came to know these guidelines while surfing :. Using Http digest - I heard this increases network traffic. This sounds costly, especially when my client is a mobile device.

Using cookies - I am told I should never rely on cookie for securing my important resources, they can be spoofed easily. Plus, I read about cross-site scripting attacks through cookies.
I am left with an option of generating authentication token ,which the user has to send everytime - which I admit is not "entirely" RESTful. Now I need to know, how should I generate these unique authentication tokens, which are secure enough at a business level?
Is there some library for Jersey? Should I go for OAuth. I have just read a little about them, are they useful in my case? Please keep in mind that my target clients are mobile devices - can they access an OAuth service?? For simplicity sake, I generate my own authentication token using UUID before encrypting the entire token with Jasypt The key contains the creationDateTime so that I can use it to verify the time-to-live. This way, if the user uses the same authentication token after X minutes, it will not work anymore, and I'll send back a forbidden code.
