xamarin uwp数字证书公钥私钥

对于数字证书存储导入到电脑中，采用如下方式：

 /// <summary>
         ///  导入证书
         /// </summary>
         /// <param name="rawData">证书字节数组</param>
         /// <param name="keyStorePassWord">keyStore密码</param>
         /// <param name="keyPassWord">证书密码</param>
         /// <param name="certificateType">证书类型</param>
         /// <returns>true表示导入成功 false表示导入失败</returns>
         public bool ImportCertificate(byte[] rawData, string keyStorePassWord, string keyPassWord, string mailAccount, CertificateType certificateType = CertificateType.Pkcs12)
         {
             try
             {
                 bool result = false;
                 if (certificateType == CertificateType.Pkcs12)
                 {
                     using (X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser))
                     {
                         store.Open(OpenFlags.ReadWrite);
                         X509Certificate2 certificate = new X509Certificate2(rawData, keyPassWord, X509KeyStorageFlags.Exportable);
                         //X509Certificate2 certificate = new X509Certificate2(rawData, keyPassWord, X509KeyStorageFlags.Exportable | X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.MachineKeySet);
                        //获取公钥
                         var cerPublicKey = certificate.Export(X509ContentType.Cert);
                         result =true;

                         store.Add(certificate);
                     }
                     return result;
                 }
                 else
                 {
                     X509Certificate2 certificate = new X509Certificate2(rawData, keyPassWord);
                     result =true;
                     return result;
                 }

             }
             catch (Exception ex)
             {
                 DAL.ErrorLog.AddErrorLogs("证书保存失败！" + ex.Message);
                 return false;
             }
         }

对应的获取相应的数字证书的私钥：

 /// <summary>
         ///  获取P12格式的证书
         /// </summary>
         /// <param name="serialNumber">证书序列号</param>
         /// <param name="keyStorePassWord">keyStore密码</param>
         /// <param name="keyPassWord">证书密码</param>
         /// <param name="hasCertificate">证书类型</param>
         /// <returns>如果返回null 表示没有获取到证书</returns>
         public byte[] GetCertificate(string serialNumber, string keyStorePassWord, string keyPassWord)
         {
             byte[] result = null;
             try
             {
                 using (X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser))
                 {
                     store.Open(OpenFlags.ReadWrite);
                     foreach (var item in store.Certificates)
                     {
                         if (item.SerialNumber == serialNumber)
                         {
                             result = item.Export(X509ContentType.Pfx, keyPassWord);
                             //result = item.RawData;
                             break;
                         }
                     }
                 }
             }
             catch (Exception ex)
             {
                 string errorMessage = ex.Message;
                 result = null;
             }
             return result;
         }

上面的result = item.Export(X509ContentType.Pfx, keyPassWord);方法需注意：当参数为两个时，及你把证书密码放上去的时候获取的是私钥，当为如下时获取的是公钥：result = item.Export(X509ContentType.Pfx);
