About JWT

What is JWT?

JSON Web Tokens (JWT) are an open standard (RFC 7519) for securely transmitting information between parties as a JSON object. JWTs can be signed using a secret or a public/private key pair, and can be encrypted to provide secrecy between parties.

Common Uses

  • Authentication and authorization
  • Information exchange between services
  • Single sign-on (SSO) implementations
  • Stateless session management
  • API request authorization

Note: This tool is for debugging and educational purposes only. For security reasons, verification is simulated and not actually performed. In real applications, token verification should be performed server-side using appropriate libraries.
