如何在使用SslMode = Preferred时找出MySQL连接的安全性

我有一个用VB.NET编写的客户端应用程序,它连接到远程MySQL服务器.
当连接安全或不安全时,我想在UI上签名.

SslMode设置为Preferred(如果服务器支持,则使用SSL,但在所有情况下都允许连接)

一旦建立了mysql连接,我该如何判断它是否是安全连接？

以下是我的连接字符串的样子：

'Declaring the MySqlConnection
_MysqlConn = New MySqlConnection( _
               New MySqlConnectionStringBuilder() _
               With { _
                 .Port = port, _
                 .Server = server, _ 
                 .UserID = username, _ 
                 .Password = password, _ 
                 .Database = database, _
                 .SslMode = MySqlSslMode.Preferred _
               }.ConnectionString
             )

如果有问题,我正在使用mysql.data(6.5.4.0).

提前谢谢你的帮助！

解决方法:

http://dev.mysql.com/doc/refman/5.6/en/using-ssl-connections.html

A client can determine whether the current connection with the server uses SSL by checking the value of the Ssl_cipher status variable. The value of Ssl_cipher is nonempty if SSL is used, and empty otherwise. For example:

mysql> SHOW STATUS LIKE 'Ssl_cipher';
+---------------+--------------------+
| Variable_name | Value              |
+---------------+--------------------+
| Ssl_cipher    | DHE-RSA-AES256-SHA |
+---------------+--------------------+

像任何常规查询一样发出此命令,并像常规结果集一样解析其结果.
