Picture Credit JSON Web Token JWT, pronounced jot’, is an open standard RFC 7519 which is used for securely transmitting information between entities as a JSON object.”It is a compact and secure way of exchanging information over the network. JSON Web Token helps to maintain the integrity and authenticity of the information because it is digitally signed using secret or public/private key pair using RSA or important thing to keep in mind about JWT is that it is a signed token and not an encrypted one. Therefore, even though JWT can verify the integrity of the claims contained within it, it cannot hide that information. And because of that, it is advisable not to put any sensitive information within the we need JSON Web Token?HTTP is a stateless protocol that means a new request does not remember anything about the previous one. So for each request, you need to login and authenticate yourself figure 1. Now, this sounds like a lot of 1So, the solution to deal with this is the use of what’s called a session. A session is an object stored on the server that helps the user to stay logged in or to save any reference to their account. Figure 2 shows the overall flow of this 2First, the user submits a username and a password that are authenticated by the server. If the authentication is successful a session ID is generated for the respective client. The generated session ID is returned to the client and is stored on the server-side as the client just needs to send its session ID along with the request to authenticate itself and retrieve necessary information. The server will then check if the session ID is valid or not. If the session is still valid, it will respond with the requested webpage/data. And if not, the server will respond with an error message stating that the request made is with Session-based AuthenticationScalability The sessions need to be stored on the server, either in memory or in a database. In the current API era, a server can receive a large number of requests, and hence the server needs to be scaled up. Adding new resources can increase the complexity of the infrastructure as Management The server needs to manage the sessions by keeping track of all the active, inactive expired, invalidated sessions. The expired or invalidated sessions need to be removed from the For every request, the server needs to perform a lookup into the memory to check if the provided session object is valid or not. This back and forth can mark down the better and effective solutionThe JSON Web Token JWT does not use sessions and hence prevents the above problems. When you send your credentials to the server instead of making a session, the server will return a JSON Web Token. You can use that JWT to do whatever you want with the server Of course, the things that you are authorized to do.Consider a JWT like a hotel key When you enter the hotel, first you need to register yourself at the reception to receive your key card. You can use that key card to open and close your room, access common amenities like Bar, Fitness Centre, etc. But you cannot use that key card to access someone else’s room or Manager’s office since you are not authorized to do so. The key card comes with an expiration date, and it becomes useless once your stay has ended at the you can use your JWT token generated from one server to access resources on different servers. The JWT token contains claims like expiration date/time that can be used to check its validity..Structure of JSON Web TokenA JSON Web Token is nothing but a long encoded text string which is made up of three parts separated by a period. These parts areHeaderPayloadSignatureA typical JWT looks like the following see detailed break down of all the three header consists of two parts the type of token and the algorithm used for signing such as HMAC SHA256 or RSA. The token type helps to interpret the token and in this case it’s JWT. For example,{"typ" "JWT","alg" "HS256"}This header is then encoded into base64 to form the first part of the payload consists of the session data called as claims. Claims provide information about the client/user. There are three types of claims registered, public, and private Claims These type of claims are predefined claims which can be used for increasing the security. These claims are not mandatory but recommended. Some of these claims areiss Issuer Claim The “iss” claim helps to identify the issuer of the Subject Claim The “sub” claim identifies the subject of the Audience Claim The “aud” claim identifies the recipients that the JWT is intended Expiration Time Claim The “exp” claim is used to identify the expiration time on or after which the JWT must not be valid. Its value must be a number containing a NumericDate value. One important thing is that the current date/time must be before the expiration date/ Not Before Claim The “nbf” claim identifies the time before which the JWT must not be accepted for processing. The current date/time must be after or equal to the not-before date/timeiat Issued At Claim The “iat” claim is used to identify the the time at which the JWT was issued. This claim can be used to determine the age of the JWT ID Claim The “jti” claim gives a unique identifier for the JWT. The “jti” value is a case-sensitive string and it should be assigned in such a manner that ensures that there is a negligible probability that the same value will be repeated. The “jti” claim can be used to prevent the JWT from being Claims These type of claims can be defined by group of people using the JWTs. Whenever any new claim name is defined it is necessary that it should be registered in the IANA “JSON Web Token Registry” or it should contain a collision resistant name to avoid Claims These are custom claims defined and created by two parties in order to exchange information between example of payload is as follows{"sub" "user123","name" "John","role" "developer","exp" "1606595460",}The payload is then Base64Url encoded to get the second part of the is the most important part of JWT which helps to verify if the information within the token has been tampered with or not. It can be also used to verify that the sender of the JWT is who it says it order to calculate the signature, you require three things an encoded header, an encoded payload, and a secret. First, you will take the encoded header and encoded payload and concatenate them with a period separator to form a string. This concatenated string will be hashed using an algorithm specified in the header and a secret key to calculate the the following example where we will be using the RSA algorithm to generate a + "." + base64UrlEncodepayload, secretNow let’s put all three parts together to get a JSON Web have three Base64-URL strings, which can be concatenated with a period between each. The JWT is very compact and can be easily exchanged in HTML and HTTP header and payload can be easily decoded since it’s just base64 to retrieve information contained within the token. The signature can be just used to maintain the integrity of the token and not to secure the contained information. Therefore, you should pass any sensitive information in the token and if you want to pass make sure you encrypt the token to secure does a JSON Web Token work?When a user sends his credentials to the server to login, the server authenticates the user. If the authorization is successful, the server sends a JSON Web Token to the user. The user can use the JWT to request any protected services/resources from the server by including the JWT in the Authorization header using the Bearer Bearer When the server gets a request from the user to access any protected content, the protected routes of the server will look for a valid JWT in the Authorization header. If the token is present and is valid the server will allow access to the JWT contains necessary information about the user that can be used to identify the user, know the user’s privilege, and serve the user accordingly. Because of JWT, the server does not need to query the database every time a request comes in to check if the user has the necessary rights or 3Every token assigned by the server is signed by a secret key known to the server only. Therefore, only the server can use the secret key to verify the token and to check if the token has tampered. If an attacker tries to make any changes in the token like granting admin privileges, the signature of the token needs to be calculated again that will require the secret key. Since the attacker does not have a secret key making any changes to the token will invalid it. The server will discard such requests to prevent unauthorized of JSON Web TokenCompactness JSON is less verbose than XML and therefore when it is encoded it takes up less space making JWT more compact then need of Session The JWT can contain all the necessary information about the user and therefore there is no need to maintain a session object on the server, saving up server Expiration The JWT has claims that can be used to assign it a expiration date/time. Therefore, the token can become invalid on its own after the expiration need of Cookies The token can be stored in the localStorage, indexDB, or some native store. This will provide a protection against CORS and CSRF In most programming languages, JSON parsers are popular because they map directly to objects. Contrary, there is no natural document-to-object mapping in XML. This makes it simpler than SAML assertions to operate with it!

TheMapbox Tokens API provides you with a programmatic way to create, update, delete, and retrieve tokens, as well as list a user's tokens and token scopes. All user accounts have a default public token. Additional tokens can be created to grant additional, or more limited, privileges. The actions allowed by a token are based on scopes.
Asked 8 years, 8 months ago Viewed 41k times When creating a web service RESTful, what status code should I use when session token is invalid? Currently the one in my company sends me a 404, not found, but I think this is not correct, because the resource exists. Maybe I should use 401 Unauthorized. What do you think? What status code do you recommend me to use in this scenario? Thanks. asked Dec 16, 2013 at 1418 401 Unauthorized. Your existing session token doesn't authorize you any more, so you are unauthorized. Don't forget that a session token is just a short-cut to avoid having to provide credentials for every request. Sending 404 is incorrect because, as you observe, the resource does exist. You just don't currently have authorization to see it. NB Don't use 403 Forbidden; the HTTP specification defines it as follows "The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated." That doesn't apply in this case as authorization WILL help. answered Dec 16, 2013 at 1422 Colin 't HartColin 't Hart6,8692 gold badges27 silver badges48 bronze badges 6 Looking through the HttpStatusCode enum, I think Unauthorized is probably the closest to what you're looking for.

Andthis token must be valid one. Normal way of doing this is: Create a login page. Login using your Work, Office or Personal Microsoft Account. Get the Access Token. Use the token and call Microsoft Graph. If you look at the above scenario we can’t login to the system and it should be a silent login.

API Gateway REST API endpoints return Missing Authentication Token errors for two reasons: The API request is made to a method or resource that doesn't exist. The API request isn't signed when the API method has AWS Identity and Access Management (IAM) authentication turned on. To troubleshoot the error, do the following.In Authorization code grant type, User is challenged to prove their identity providing user credentials. Upon successful authorization, the token end point is used to obtain an access token. The obtained token is sent to the resource server and gets validated before sending the secured data to the client application. To protect an API with Azure AD, first register an application in Azure AD that represents the API. The following steps use the Azure portal to register the application. First we need to access our the AAD tenant we created in the excercise before, be sure you are in the right tenant. Then select App registrations under Azure Portal to register an application Select New registration. In the Name section, enter a meaningful application name that will be displayed to users of the app. For example oauth-backend-app In the Supported account types section, select an option that suits your scenario. Leave the Redirect URI section empty. Select Register to create the application. On the app Overview page, find the Application client ID value and record it for later. Select Expose an API and set the Application ID URI with the default value. Record this value for later. Select the Add a scope button to display the Add a scope page. Then create a new scope that’s supported by the API for example, Select the Add scope button to create the scope. Repeat this step to add all scopes supported by your API. When the scopes are created, make a note of them for use in a subsequent step. Every client application that calls the API needs to be registered as an application in Azure AD. In this example, the client application is the Developer Console in the API Management developer portal. In this case we will register another application in Azure AD to represent the Developer Console Select New registration. In the Name section, enter a meaningful application name that will be displayed to users of the app. For example oauth-client-app In the Supported account types section, select an option that suits your scenario. Leave the Redirect URI section empty. Select Register to create the application. On the app Overview page, find the Application client ID value and record it for later. Create a client secret for this application to use in a subsequent step. From the left menu options for your client app, select Certificates & secrets, and select New client secret. Under Add a client secret, provide a Description. Choose when the key should expire and select Add. When the secret is created, note the key value for use in a subsequent step. Grant permissions for client-app to call backend-app Now we have to open our client app and choose the option API permissions In here we need to click on Add a permission Then choose My APIs Select the record for backend-app-oauth Then select the Delegated Permissions option Then mark the checkbox Then click the Add Permissions button Finally click the Grant admin consent for ... Enable OAuth in the Developer Console for Authorization Code Grant type At this point, we have created the applications in Azure AD, and granted proper permissions to allow the client-app to call the backend-app. In this demo, the Developer Console is the client-app and has a walk through on how to enable OAuth user authorization in the Developer Console. Steps mentioned below In Azure portal, browse to your API Management instance and Select OAuth > Add. Provide a Display name and Description. For the Client registration page URL, enter a placeholder value, such as http//localhost. For Authorization grant types, select Authorization code. Specify the Authorization endpoint URL and Token endpoint URL. These values can be retrieved from the Endpoints page in your Azure AD tenant. Browse to the client App registrations page again and select Endpoints. Endpoints versions We recommend using v2 endpoints. When using v2 endpoints, use the scope you created for the backend-app in the Default scope field. Also, make sure to set the value for the accessTokenAcceptedVersion property to 2 in your application manifest in Azure AD Client APP and Backend app. Next, specify the client credentials. These are the credentials for the client-app. For Client ID, use the Application ID of the client-app. For Client secret, use the key you created for the client-app earlier. Immediately following the client secret is the redirect_urls Go back to your client-app registration in Azure Active Directory under Authentication. Paste the redirect_url under Redirect URI, and check the issuer tokens then click on Configure button to save. Now that you have configured an OAuth authorization server, the Developer Console can obtain access tokens from Azure AD. The next step is to enable OAuth user authorization for your API. This enables the Developer Console to know that it needs to obtain an access token on behalf of the user, before making calls to your API. Go to APIs menu under the APIM Select the Basic Calculator API and Go to Settings. Under Security, choose OAuth select the OAuth server you configured earlier and select save. Publish the developer portal again to refresh this changes Calling the API from the Developer Portal Now that the OAuth user authorization is enabled on your API, the Developer Console will obtain an access token on behalf of the user, before calling the API. Copy the developer portal url from the overview blade of apim Browse to any operation under the Basic Calculator API in the developer portal and select Try it. This brings you to the Developer Console. Note a new item in the Authorization section, corresponding to the authorization server you just added. Select Authorization code from the authorization drop-down list, and you are prompted to sign in to the Azure AD tenant. If you are already signed in with the account, you might not be prompted. After successful sign-in, an Authorization header is added to the request, with an access token from Azure AD. The following is a sample token Base64 encoded Select Send to call the API successfully with 200 ok response. At this point we can call the APIs with the obtained bearer token. However, what if someone calls your API without a token or with an invalid token? For example, try to call the API without the Authorization header, the call will still go through. This is because the API Management does not validate the access token, It simply passes the Authorization header to the back-end API. To pre-Authorize requests, we can use validate-jwt Policy by validating the access tokens of each incoming request. If a request does not have a valid token, API Management blocks it. We will now configure the Validate JWT policy to pre-authorize requests in API Management, by validating the access tokens of each incoming request. If a request does not have a valid token, API Management blocks it. Browses to the APIs from the left menu of APIM Click on Basic Calculator Api and open the inbound policy to add the validate-jwt policyIt checks the audience claim in an access token and returns an error message if the token is not valid. and save it. You will need to get the id of your scope, you set from you backend-app registration. Normally this comes in the form api//d183fdbe-fc28-4ef7-9ca1-e7b4a4cd1ff8/ , we need to use the id d183fdbe-fc28-4ef7-9ca1-e7b4a4cd1ff8 as audience YOUR-BACKENDAPP-SCOPE-ID Go back to the developer portal and send the api with invalid token. You would observe the 401 unauthorized. Modify the token from authorization header to the valid token and send the api again to observe the 200-ok response. Understanding validate-jwt Policy In this section, we will be focusing on understanding how validate-jwt policy works the image in the right side is the decoded JWT Token The validate-jwt policy supports the validation of JWT tokens from the security viewpoint, It validates a JWT JSON Web Token passed via the HTTP Authorization header If the validation fails, a 401 code is returned. The policy requires an openid-config endpoint to be specified via an openid-config element. API Management expects to browse this endpoint when evaluating the policy as it has information which is used internally to validate the token. Please Note OpenID config URL differs for the v1 and v2 endpoints. The required-claims section contains a list of claims expected to be present on the token for it to be considered valid. The specified claim value in the policy must be present in the token for validation to succeed. The claim value should be the Application ID of the Registered Azure AD Backend-APP.vRFZV.
