![]() This highlights the ease of client-side processing of the JSON Web token on multiple platforms, especially mobile. Regarding usage, JWT is used at Internet scale. This makes it easier to work with JWT than SAML assertions. Conversely, XML doesn't have a natural document-to-object mapping. JSON parsers are common in most programming languages because they map directly to objects. Signing XML with XML Digital Signature without introducing obscure security holes is very difficult when compared to the simplicity of signing JSON. However, JWT and SAML tokens can use a public/private key pair in the form of a X.509 certificate for signing. Security-wise, SWT can only be symmetrically signed by a shared secret using the HMAC algorithm. We welcome and appreciate all contributions to djwt. The following projects use djwt: AuthCompanion: An effortless, token-based user management server - well suited for modern web projects. This makes JWT a good choice to be passed in HTML and HTTP environments. JSON Web Token JSON Web Signature JSON Web Algorithms Applications. Additionally, as the signature is calculated using the header and the payload, you can also verify that the content hasn't been tampered with.Īs JSON is less verbose than XML, when it is encoded its size is also smaller, making JWT more compact than SAML. Because JWTs can be signed-for example, using public/private key pairs-you can be sure the senders are who they say they are. Information exchange: JSON Web Tokens are a good way of securely transmitting information between parties. Single Sign On is a feature that widely uses JWT nowadays, because of its small overhead and its ability to be easily used across different domains. Once the user is logged in, each subsequent request will include the JWT, allowing the user to access routes, services, and resources that are permitted with that token. When should you use JSON Web Tokens? #Īuthorization: This is the most common scenario for using JWT. ![]() The JWT can be signed using a secret (using the HMAC algorithm) or using a public/private key pair of RSA or ECDSA. Since this information is digitally signed, it can be verified and trusted. JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and independent method for securely transmitting information as JSON objects between parties.
