我想创建一个应用程序使用 SSLSocket :客户端向服务器发送一个 String ,服务器将大写 String 并发送回客户端以供显示。



SSLServer



  public class SSLServer {
public static void main(String args [])throws Exception
{
try {
// Creaet a SSLServersocket
SSLServerSocketFactory factory =(SSLServerSocketFactory)SSLServerSocketFactory.getDefault();
SSLServerSocket sslserversocket =(SSLServerSocket)factory.createServerSocket(1234);
//Tạo1đốitượngSockettừserversocketđlắngnghevàchấpnậnkếtnốitừclient
SSLSocket sslsocket =(SSLSocket)sslserversocket.accept();
// Tao cac luong de nhan va gui du lieu cua client
DataInputStream is = new DataInputStream(sslsocket.getInputStream());
PrintStream os = new PrintStream(sslsocket.getOutputStream());
while(true)// khi dang ket noi voi client
{
// Doc du lieu den
String input = is.readUTF();
String ketqua = input.toUpperCase();
// Du lieu tra ve
os.println(ketqua);
}
}
catch(IOException e)
{
System.out.print(e);
}
}
}



SSLClient



 公共类SSLClient {
public static void main(String args [])
{
try
{
// Mo 1客户端套接字服务器voi so cong va dia chi xac dinh
SSLSocketFactory factory =(SSLSocketFactory)SSLSocketFactory.getDefault();
SSLSocket sslsocket =(SSLSocket)factory.createSocket(127.0.0.1,1234);

// Tao luong nhan va gui du lieu len server
DataOutputStream os = new DataOutputStream(sslsocket.getOutputStream());
DataInputStream = new DataInputStream(sslsocket.getInputStream());

// Gui du lieu len server
String str =helloworld;
os.writeBytes(str);

// Nhan du lieu da qua xu li tu server ve
String responseStr;
if((responseStr = is.readUTF())!= null)
{
System.out.println(responseStr);
}

os.close();
is.close();
sslsocket.close();
}
catch(UnknownHostException e)
{
System.out.println(e.getMessage());
}
catch(IOException e)
{
System.out.println(e.getMessage());
}
}
}

运行时 SSLServer 。它显示以下错误:

  javax.net.ssl.SSLException:没有可用的证书或密钥对应SSL的
密码套件已启用

我有搜索并做某些方法但是..你能帮助我吗?这将生成证书:

 $ c> keytool -genkey -keystore yourKEYSTORE -keyalg RSA 

输入yourPASSWORD,然后使用ssl启动服务器调试信息(将yourKEYSTORE放入SSLServer.class目录):

  java -Djavax.net.ssl.keyStore = yourKEYSTORE -Djavax .net.ssl.keyStorePassword = yourPASSWORD -Djava.protocol.handler.pkgs = com.sun.net.ssl.internal.www.protocol -Djavax.net.debug = ssl SSLServer 

比启动客户端(将yourKEYSTORE放入SSLClient.class目录):

  java -Djavax.net.ssl.trustStore = yourKEYSTORE -Djavax.net。 ssl.trustStorePassword = yourPASSWORD SSLClient 


I want to create an app use SSLSocket: client send a String to server and server will uppercase that String and send back to client for display.

SSLServer

public class SSLServer {
    public static void main(String args[]) throws Exception
    {
        try{
        //Creaet a SSLServersocket
        SSLServerSocketFactory factory=(SSLServerSocketFactory) SSLServerSocketFactory.getDefault();
        SSLServerSocket sslserversocket=(SSLServerSocket) factory.createServerSocket(1234);
        //Tạo 1 đối tượng Socket từ serversocket để lắng nghe và chấp nhận kết nối từ client
        SSLSocket sslsocket=(SSLSocket) sslserversocket.accept();
        //Tao cac luong de nhan va gui du lieu cua client
        DataInputStream is=new DataInputStream(sslsocket.getInputStream());
        PrintStream os=new PrintStream(sslsocket.getOutputStream());
        while(true)  //khi dang ket noi voi client
        {
            //Doc du lieu den
            String input=is.readUTF();
            String ketqua=input.toUpperCase();
            //Du lieu tra ve
            os.println(ketqua);
        }
        }
        catch(IOException e)
        {
           System.out.print(e);
        }
    }
}

SSLClient

public class SSLClient {
    public static void main(String args[])
    {
        try
        {
        //Mo 1 client socket den server voi so cong va dia chi xac dinh
        SSLSocketFactory factory=(SSLSocketFactory) SSLSocketFactory.getDefault();
        SSLSocket sslsocket=(SSLSocket) factory.createSocket("127.0.0.1",1234);

        //Tao luong nhan va gui du lieu len server
        DataOutputStream os=new DataOutputStream(sslsocket.getOutputStream());
        DataInputStream is=new DataInputStream(sslsocket.getInputStream());

        //Gui du lieu len server
        String str="helloworld";
        os.writeBytes(str);

        //Nhan du lieu da qua xu li tu server ve
        String responseStr;
        if((responseStr=is.readUTF())!=null)
        {
            System.out.println(responseStr);
        }

        os.close();
        is.close();
        sslsocket.close();
        }
        catch(UnknownHostException e)
        {
             System.out.println(e.getMessage());
        }
        catch(IOException e)
        {
            System.out.println(e.getMessage());
        }
    }
}

When run SSLServer. It displays this error:

javax.net.ssl.SSLException: No available certificate or key corresponds
    to the SSL cipher suites which are enabled

I have search and do some ways but.. Can you help me.

解决方案

This will generate certificate:

keytool -genkey -keystore yourKEYSTORE -keyalg RSA

Enter yourPASSWORD and than start your server with ssl debug information(put yourKEYSTORE into directory with SSLServer.class):

java -Djavax.net.ssl.keyStore=yourKEYSTORE -Djavax.net.ssl.keyStorePassword=yourPASSWORD -Djava.protocol.handler.pkgs=com.sun.net.ssl.internal.www.protocol -Djavax.net.debug=ssl SSLServer

Than start your client(put yourKEYSTORE into directory with SSLClient.class):

java -Djavax.net.ssl.trustStore=yourKEYSTORE -Djavax.net.ssl.trustStorePassword=yourPASSWORD SSLClient
