![]() ![]() ![]() Create a worker app connection and click the “Get Access Token” button on the configuration page for that app connection. Read the decoded outputs for the header and payload!Īn easy way to try out the tool is to sign up for a free trial of PingOne for Customers.Grab a JWT you want to decode, or a JWS or JWE containing a JWT.The token is entirely decoded client side in the browser, so make sure to take proper precautions to protect your token! First, remember that JWTs are tokens that are often used as the credentials for SSO applications.In our example above it would be the encoded header concatenated with the encoded JWT claims set encoded with the HMAC SHA-256 algorithm. The signature is the header and payload (JWT claims set) encoded using the algorithm specified in the header. These are some common claim names, but they will vary depending on the application and service being used. This payload has an audience (“aud”) of the PingOne for Customers API, an issuer (“iss”) of the PingOne for Customers Authorization Server, and has a set expiration date (“exp”). For example, take a look at the following payload: The payload contains the JWT object itself, and the JWT itself is just a set of claims. It’s intended to avoid confusion when different types are being used. The type may be left out if the JWSs and JWEs used by the application are JWT types. The payload with a JWE including this header will be of a JWT signed and encrypted with the HMAC SHA-256 algorithm. This tells us that we have a JWT that is integrity protected with the HMAC SHA-256 algorithm. For example, take a look at the following header: The header includes information about how the JWT claims set, the payload, is encoded. The main parts are encoded then concatenated with a “.” separating them, so that it looks like Signature: An encoding of the header and payload.Header: The type of encoded object in the payload and any extra encoding.There are three main parts of a JWS or JWE that include a JWT claim: However, the entire string is often referred to as a JWT if the payload is an encoded JWT object. Technically, a JWT is represented as a JWS (JSON Web Signature) object or a JWE (JSON Web Encryption) object. They can be encrypted or digitally signed so the information can be passed around securely.Compact representation of information about a subject or user.Instead, your information can be passed between domains in the JWT, so the second domain knows who you are and that you have already been authenticated by a trusted party. ![]() This can enable single sign-on (SSO), which means you do not have to sign in again to another domain owned by the same company. A JWT is an open-standards approach to securely sharing information between a client and a server in a compact, self-contained way that provides stateless authentication.įor example, after you sign in to a website, information about your account is encoded and passed around to the relevant parties in a JWT. Claims are encoded JSON objects that include some information about a subject and are often used in identity security applications to transfer information about a user. A JSON Web Token (JWT, pronounced “jot”) is a token for sharing claims. ![]()
