ДЖВТ Декодер

Декодировать и анализировать токены JWT

JWT Token (JSON Web Token)

⚠️ Importante

Esta herramienta solo DECODIFICA el JWT (no lo verifica). Los JWT están codificados en Base64, NO encriptados.

Nunca compartas JWTs que contengan información sensible. Cualquiera puede leer el contenido de un JWT.

La verificación de la firma debe hacerse en el servidor usando la clave secreta.
