## Über JWT

JWT bedeutet „JSON Web Tokens“.

Es ist ein Standard, um ein JSON-Objekt in einem langen, kompakten String ohne Leerzeichen zu kodieren. Das sieht so aus:

```

```

Vamos a empezar desde donde lo dejamos en el capítulo anterior e incrementarlo.

## Acerca de JWT

JWT significa "JSON Web Tokens".

Es un estándar para codificar un objeto JSON en un string largo y denso sin espacios. Se ve así:
