Difference between JWT and SAML?

What is the main difference between JWT (Json Web Token) and SAML? Please offer me any spring security example. Thanks in advance.

Both SAML and JWT are security token formats that are independent of any programming language. SAML is an older format and is based on XML. It is commonly used in protocols such as SAML-P, WS-Trust, and WS-Federation (although not required).

JWT tokens (JSON Web Token) are based on JSON and are used in new authentication and authorization protocols such as OpenID Connect and OAuth 2.0.

Additional information is that SAML is the protocol and format of the token, but JWT is the only format of the token.

Both are used to exchange authentication and authorization data between the parties, but in a different format. SAML is a markup language (such as XML), and JWT is JSON.

SAML ( ssertion arkup anguage) is an open standard for the exchange of authentication and authorization data between parties, in particular, between IED (Id entity P rovider) and IP ( EP rovider), and this identity protocols are used in corporate deployments.

  • IdP ( Id entity P rovider): authenticates users and provides service providers with authentication confirmation if successful;
  • SP (C ro rider): Depends on the identity provider for user authentication.

SAML in Auth0

JWT ( J SON Web e Token) is an open standard (RFC 7519) that defines a compact and stand-alone way to safely transfer information between parties as a JSON object. This information can be verified and reliable because it is digitally signed. JWTs can be signed using secret (using the HMAC algorithm) or public / private key pairs using RSA.

JWT in Auth0

Usecase :

The single most important use case for SAML is single sign-on to a web browser (single sign-on, i.e. logging in once and receiving a token without having to log in to other services). Single sign-on is relatively easy to do in a security domain (for example, using cookies), but expanding single sign-on through security domains is more complex and has led to the spread of incompatible proprietary technologies. The SAML Web Browser single sign-on profile has been defined and standardized for compatibility. (For comparison, the later OpenID Connect protocol is an alternative approach to the SSO of a web browser.) The id_token token , usually called the id_token in the id_token code, is a JSON Web Token (JWT) that contains user profile information.
