GetCertificate

O exemplo de Java a seguir mostra como usar a GetCertificateoperação.

A operação recupera um certificado do CA privado. O ARN do certificado é retornado quando você chama a IssueCertificateoperação. Você deve especificar o ARN da CA privada e o ARN do certificado emitido ao chamar a operação GetCertificate. Você pode recuperar o certificado se ele estiver no estado ISSUED. Você pode chamar a CreateCertificateAuthorityAuditReportoperação para criar um relatório que contenha informações sobre todos os certificados emitidos e revogados pela sua CA privada.

Sua saída deve ser uma cadeia de certificados semelhante à seguir para a autoridade de certificação (CA) e o certificado que você especificou.
