JWT - JSON Web Token
What is a JWT?
A JSON Web Token (JWT) is a standard for creating tokens that assert some number of claims. These tokens are used to secure communications between parties by allowing the parties to trust each other based on the claims that are asserted in the token. JWTs are commonly used in situations where it is necessary to securely transmit information between two parties, such as in authentication and authorization systems.
JSON Web Token characteristics
Some benefits of using JSON Web Tokens (JWTs) include:
-
JWTs are self-contained, which means that all the necessary information about a user is included in the token itself. This allows for easy, secure transmission of user information between parties without the need for a shared database or other centralized mechanism for storing authentication information.
-
JWTs are digitally signed, which means that the parties that receive the token can trust that the information contained in the token is authentic and has not been tampered with.
-
JWTs can be easily used in a wide variety of contexts, including authentication and authorization systems, single sign-on (SSO) systems, and microservice architectures.
-
JWTs are standardized and well-supported, which means that there are many libraries and tools available for generating, parsing, and validating JWTs. This makes it easy to integrate JWTs into existing applications and systems.
-
JWTs are compact and efficient, which makes them well-suited for use in environments where bandwidth or other resources are limited.
Overall, the use of JWTs can provide a number of benefits in terms of security, flexibility, and efficiency in a variety of contexts.
