La especificación de JWT dice que hay una clave `sub`, con el sujeto del token.

Es opcional usarlo, pero ahí es donde pondrías la identificación del usuario, por lo que lo estamos usando aquí.

JWT podría ser usado para otras cosas aparte de identificar un usuario y permitirle realizar operaciones directamente en tu API.

Por ejemplo, podrías identificar un "coche" o un "artículo de blog".
