Exemplos de um token de certificação

A política de atestado é usada para processar a evidência de atestado e determina se o Atestado do Azure emite um token de atestado. A geração de tokens de atestado pode ser controlada com políticas personalizadas. Aqui estão alguns exemplos de um token de atestado.

Algumas das declarações usadas aqui são consideradas obsoletas, mas são totalmente suportadas. Recomenda-se que todos os códigos e ferramentas futuros usem os nomes de declaração não preteridos. Para obter mais informações, consulte declarações emitidas pelo Atestado do Azure.

As declarações abaixo aparecem apenas no token de atestado gerado para plataformas de servidor baseadas no processador Intel® Xeon® Scalable. As declarações não aparecem se o enclave SGX não estiver configurado com o Suporte a Separação e Compartilhamento de Chaves.
