They’re quickly becoming a de facto standard for token implementations across the web. They are generally encoded and encrypted. Typically, they carry information about a user’s verified identity. To say this another way: JWTs are a JSON token that is a URL-safe, compact, and self-contained string. They can be signed with the HMAC algorithm or using a public/private key pair using RSA or ECDSA. What is a JSON Web Token? A JWT is an open standard ( RFC 7519) for using JSON to transmit information between parties as digitally signed string tokens. I’ll show you a particular type of token that does have intrinsic value and addresses a number of concerns with session IDs.
Let’s first examine what authentication and token mean in this context.Īuthentication is proving that a user is who they say they are.Ī token is a self-contained singular chunk of information. Understand JWTs and Their Role in Authentication You’re going to be using Java JWT (a.k.a., JJWT), a Java library that provides end-to-end JWT creation and verification.

In this post, you'll take a deep dive into JWTs beginning with how they work, and then digging into how to configure a Spring Boot app with Okta to use JWT authentication.īecause JSON Web Tokens are an open standard, there are various libraries available that allow the creation, verification, and inspection of JWTs. They also give us the benefit of inspectable metadata and strong cryptographic signatures. Used properly, they address a range of security concerns, including cross-site scripting attacks (XSS), man-in-the-middle attacks (MITM), and cross-site request forgery (CSRF). JSON Web Tokens are the standard for securing modern web applications.
