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：

 1 /// 

 2         ///  导入证书
 3         /// 
 4         /// 证书字节数组
 5         /// keyStore密码
 6         /// 证书密码
 7         /// 证书类型
 8         /// true表示导入成功 false表示导入失败
 9         public bool ImportCertificate(byte[] rawData, string keyStorePassWord, string keyPassWord, string mailAccount, CertificateType certificateType = CertificateType.Pkcs12)
10         {
11             try
12             {
13                 bool result = false;
14                 if (certificateType == CertificateType.Pkcs12)
15                 {
16                     using (X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser))
17                     {
18                         store.Open(OpenFlags.ReadWrite);
19                         X509Certificate2 certificate = new X509Certificate2(rawData, keyPassWord, X509KeyStorageFlags.Exportable);
20                         //X509Certificate2 certificate = new X509Certificate2(rawData, keyPassWord, X509KeyStorageFlags.Exportable | X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.MachineKeySet);
21                        //获取公钥
22                         var cerPublicKey = certificate.Export(X509ContentType.Cert);
23                         result =true;
24 
25                         store.Add(certificate);
26                     }
27                     return result;
28                 }
29                 else
30                 {
31                     X509Certificate2 certificate = new X509Certificate2(rawData, keyPassWord);
32                     result =true;
33                     return result;
34                 }
35 
36             }
37             catch (Exception ex)
38             {
39                 DAL.ErrorLog.AddErrorLogs("证书保存失败！" + ex.Message);
40                 return false;
41             }
42         }

对应的获取相应的数字证书的私钥：

 1 /// 

 2         ///  获取P12格式的证书
 3         /// 
 4         /// 证书序列号
 5         /// keyStore密码
 6         /// 证书密码
 7         /// 证书类型
 8         /// 如果返回null 表示没有获取到证书
 9         public byte[] GetCertificate(string serialNumber, string keyStorePassWord, string keyPassWord)
10         {
11             byte[] result = null;
12             try
13             {
14                 using (X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser))
15                 {
16                     store.Open(OpenFlags.ReadWrite);
17                     foreach (var item in store.Certificates)
18                     {
19                         if (item.SerialNumber == serialNumber)
20                         {
21                             result = item.Export(X509ContentType.Pfx, keyPassWord);
22                             //result = item.RawData;
23                             break;
24                         }
25                     }
26                 }
27             }
28             catch (Exception ex)
29             {
30                 string errorMessage = ex.Message;
31                 result = null;
32             }
33             return result;
34         }

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);
