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);
