从.net core通过M2MQTT连接到AWS IoT

我设法手动创建了AWS物联网配置，下载了证书，并创建了一个可以订阅主题的控制台应用程序。我现在正在尝试自动创建东西，这将导致AWS以字符串形式提供证书密钥。我不知道如何使用这些。我已经下载了根ca，我想我所有的东西都使用它

我的基于文件的证书订阅者如下所示：

            Console.WriteLine("AWS IOT Dotnet core message listener starting");
            string iotendpoint = "blahblah-ats.iot.ap-southeast-2.amazonaws.com";
            int BrokerPort = 8883;
            string Topic = "topic_1/";

            var CaCert = X509Certificate.CreateFromCertFile(@"root-CA.crt");
            var ClientCert = new X509Certificate2(@"device.pfx", "password");

            var IotClient = new MqttClient(iotendpoint, BrokerPort, true, CaCert, ClientCert, MqttSslProtocols.TLSv1_2);

            try
            {
                IotClient.Connect(Guid.NewGuid().ToString());
                Console.WriteLine("Connected to AWS IOT");

                IotClient.MqttMsgPublishReceived += Client_MqttMsgPublishReceived;
                IotClient.MqttMsgSubscribed += Client_MqttMsgSubscribed;

                IotClient.Subscribe(new string[] { Topic }, new byte[] { MqttMsgBase.QOS_LEVEL_AT_LEAST_ONCE });

                Console.ReadLine();

            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                return;
            }

    var keyText = File.ReadAllText("keys.json"); // saved from AWS SDK when creating IoT Cert.
    var keys = JsonConvert.DeserializeObject<Keys>(keyText);
    var rsa = RsaHelper.PrivateKeyFromPem(keys.PrivateKey);

    var pemText = File.ReadAllText("thing.crt");
    var bytes = Encoding.ASCII.GetBytes(pemText);

    var ClientCert = new X509Certificate2(bytes);
    ClientCert = ClientCert.CopyWithPrivateKey(rsa);
    ClientCert = new X509Certificate2(ClientCert.Export(X509ContentType.Pfx,"12345678"), "12345678");

要从文件加载证书，我尝试了以下操作：

    var keyText = File.ReadAllText("keys.json");
    var keys = JsonConvert.DeserializeObject<Keys>(keyText);
    var bytes = Encoding.ASCII.GetBytes(keys.PrivateKey.ToCharArray());
    var ClientCert = new X509Certificate2(bytes);

以及json文件中AWS的密钥：

{
    "PrivateKey": "-----BEGIN RSA PRIVATE KEY-----\nMIIEpQIBAAKCAQEA4mh2PQ581XN9BmoCvDjlaktm/6gQgqGBItZThcQVMTjveU8H\npjOU2E/9lq7vmdO+96NuuMr9MKtFD+ZWtVExLjMq9hH0MvIvosVt9+6Ggcwz7Kdr\nigprfBMVORV0rgcK+nsd2DmBNrs339fqbTn5UAIFFBpqkNReW7LMl9h6g8hu4aYQ\nJTohDwSmgmNJKlzMJGtVfPggqt+bBi3lUf9NEOEz...
-----END RSA PRIVATE KEY-----\n",
    "PublicKey": "-----BEGIN PUBLIC KEY-----\nMIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA4mh2PQ581XN9BmoCvDjl\naktm/6gQgqGBItZThcQVMTjveU8HpjOU2E/9lq7vmdO+96NuuMr9MKtFD+ZWtVEx\nLjMq9hH0MvIvosVt9+6Ggcwz7K...
-----END PUBLIC KEY-----\n"
}

我在加载证书时出错：

System.Security.Cryptography.X509Certificates.dll中发生类型为“Internal.Cryptography.CryptothWhelper.WindowsCryptographyException”的未处理异常：“找不到请求的对象。”

有人能看出这里有什么明显的错误吗？我不明白

更新：

使用AWS SDK生成的PEM文本更为正确，但我仍然在连接时遇到错误-M2MQTT表示存在证书问题，它没有私钥。它需要它吗

    var pemText = File.ReadAllText("thing.crt");
    var bytes = Encoding.ASCII.GetBytes(pemText);
    var ClientCert = new X509Certificate2(bytes);

最终的拼凑解决方案如下所示：

            Console.WriteLine("AWS IOT Dotnet core message listener starting");
            string iotendpoint = "blahblah-ats.iot.ap-southeast-2.amazonaws.com";
            int BrokerPort = 8883;
            string Topic = "topic_1/";

            var CaCert = X509Certificate.CreateFromCertFile(@"root-CA.crt");
            var ClientCert = new X509Certificate2(@"device.pfx", "password");

            var IotClient = new MqttClient(iotendpoint, BrokerPort, true, CaCert, ClientCert, MqttSslProtocols.TLSv1_2);

            try
            {
                IotClient.Connect(Guid.NewGuid().ToString());
                Console.WriteLine("Connected to AWS IOT");

                IotClient.MqttMsgPublishReceived += Client_MqttMsgPublishReceived;
                IotClient.MqttMsgSubscribed += Client_MqttMsgSubscribed;

                IotClient.Subscribe(new string[] { Topic }, new byte[] { MqttMsgBase.QOS_LEVEL_AT_LEAST_ONCE });

                Console.ReadLine();

            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                return;
            }

    var keyText = File.ReadAllText("keys.json"); // saved from AWS SDK when creating IoT Cert.
    var keys = JsonConvert.DeserializeObject<Keys>(keyText);
    var rsa = RsaHelper.PrivateKeyFromPem(keys.PrivateKey);

    var pemText = File.ReadAllText("thing.crt");
    var bytes = Encoding.ASCII.GetBytes(pemText);

    var ClientCert = new X509Certificate2(bytes);
    ClientCert = ClientCert.CopyWithPrivateKey(rsa);
    ClientCert = new X509Certificate2(ClientCert.Export(X509ContentType.Pfx,"12345678"), "12345678");

var keyText=File.ReadAllText（“keys.json”）；//创建物联网证书时从AWS SDK保存。
var keys=JsonConvert.DeserializeObject（keyText）；
var rsa=rsaheloper.PrivateKeyFromPem（key.PrivateKey）；
var pemText=File.ReadAllText（“thing.crt”）；
var bytes=Encoding.ASCII.GetBytes（pemText）；
var ClientCert=新的X509Certificate2（字节）；
ClientCert=ClientCert.CopyWithPrivateKey（rsa）；
ClientCert=new X509Certificate2（ClientCert.Export（X509ContentType.Pfx，“12345678”），“12345678”）；
