Получение ключевой ошибки при анализе сертификата x509 на Android

Question

Когда я пытаюсь проанализировать свой сертификат x509 для Android, я получаю сообщение об ошибке фабричного ключа

Я сгенерировал свои сертификаты x509 из https://github.com/Azure/azure-iot-sdk-java/tree/master/provisioning/provisioning-tools/provisioning-x509-cert-generator

ProvisioningX509Sample.main(response.getString("Leaf_Public_Pem"),response.getString("Leaf_Private_Key"),response.getString("Ca_Signer"), response.getString("IoThub_url"), response.getString("Device_Id"));

ошибка
