问在java中，SSL可以用一个密钥进行加密和解密吗？

        //Specifying the Keystore details
        System.setProperty("javax.net.ssl.keyStore","testkeystore.ks");
        System.setProperty("javax.net.ssl.keyStorePassword","mypass");

        // Enable debugging to view the handshake and communication which happens between the SSLClient and the SSLServer
        // System.setProperty("javax.net.debug","all");
    }


            // Initialize the Server Socket
            SSLServerSocketFactory sslServerSocketfactory = (SSLServerSocketFactory)SSLServerSocketFactory.getDefault();
            sslServerSocket = (SSLServerSocket)sslServerSocketfactory.createServerSocket(intSSLport);

    {
        // Registering the JSSE provider
        Security.addProvider(new Provider());
    }

    try {
        // Creating Client Sockets
        SSLSocketFactory sslsocketfactory = (SSLSocketFactory)SSLSocketFactory.getDefault();
        SSLSocket sslSocket = (SSLSocket)sslsocketfactory.createSocket(strServerName,intSSLport);
