Active una CA raíz para los certificados operativos de los nodos (NOC).

Este ejemplo de Java muestra cómo usar la Definición de ootCACertificate APIPassthrough R_/V1 plantilla para crear e instalar un certificado de CA Matter Root para emitirloNOCs. La extensión AuthorityKeyIdentifier (AKI) es opcional para los certificados de CA NOC raíz. Para establecer unAKI, debe generar un AKI valor codificado en Base64 y pasarlo por un. CustomExtension

El ejemplo llama a las siguientes acciones: Autoridad de certificación privada de AWS API
