常见的Java套接字中没有密码套件 [英] No cipher suites in common java sockets

问题描述

我最近一直在为邮件系统使用SSL套接字。

I have been using SSL sockets for a messaging system recently.

我终于开始使用CA颁发的证书了。我将它导入我的密钥库，设置了密钥库属性，并启动了我的客户端，但是当我尝试发送数据时，我一直收到握手异常。

I finally started using a CA issued certificate. I imported it into my keystore, set the keystore property, and started up my client, but I keep getting handshake exceptions when I try to send data.

我启用了调试模式我发现这是由于没有支持密码套件。对此有何看法？

I enabled debug mode and I found that it is due to no cipher suites supported. Any thoughts on this?

如果有帮助，它还说它忽略了TLSV1和TLSV1.1的10个密码套件。

If it helps, It also says that it is ignoring about 10 cipher suites from TLSV1 and TLSV1.1.

我还安装了无限强度加密政策。

I also installed Unlimited Strength Cryptographic Policy.

客户代码

public static void Message(String args){
    System.setProperty("https.protocols", "TLSv1");
    System.setProperty("javax.net.debug", "all");

    try
    {
        String host = "localhost";
        int port = 3498;
        InetAddress address = InetAddress.getByName(host);

        socket = (SSLSocket)SSLSocketFactory.getDefault().createSocket(address, port);

        //Send the message to the server
        OutputStream os = socket.getOutputStream();
        OutputStreamWriter osw = new OutputStreamWriter(os);
        BufferedWriter bw = new BufferedWriter(osw);

        String number = "Hello from the other side!";

        String sendMessage = number + "\n";
        bw.write(args);
        bw.flush();
        System.out.println("Message sent to the server : "+sendMessage);

        //Get the return message from the server

    }
    catch (Exception exception)
    {
        exception.printStackTrace();
    }
    finally
    {
        //Closing the socket
        try
        {
            socket.close();
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }
}

服务器代码

private void initListen() {
    System.setProperty("javax.net.ssl.keyStore", "/Users/181095/server.jks");
    try {


        SSLServerSocketFactory sf = (SSLServerSocketFactory)SSLServerSocketFactory.getDefault();

        SSLServerSocket serverSocket = (SSLServerSocket)sf.createServerSocket(Ting.port);



        System.out.println("Server Started and listening to the port "
                + Ting.port);

        // Server is running always. This is done using this while(true)
        // loop
        while (true) {

            // Reading the message from the client
            socket = (SSLSocket)serverSocket.accept();


            InputStream is = socket.getInputStream();
            InputStreamReader isr = new InputStreamReader(is);
            BufferedReader br = new BufferedReader(isr);
            String input = br.readLine();
            System.out.println("Message received from client is " + input);
            /*if(PacketReader.isPacket(input)){
                if(PacketReader.shouldSendDataBack(input)){

                }
            }*/
            /*
             * 
             * if client has data waiting or client has new data
             * request new data.
             * else, wait 5 seconds and repeat
             * 
             * 
             */



            // Sending the response back to the client.
            /*OutputStream os = socket.getOutputStream();
            OutputStreamWriter osw = new OutputStreamWriter(os);
            BufferedWriter bw = new BufferedWriter(osw);
            bw.write("");*/

            //TODO Implement method to send this data to client storage data.

            //bw.flush();
        }
    //Check for exceptions and try to close the socket.
    } catch (Exception e) {

        e.printStackTrace();
        } finally {
            try {
                socket.close();
            } catch (Exception e) {
        }
    }
}

编辑：
我刚刚添加了密码，但我的输入/证书没有密钥，这是否会导致错误？我该如何解决？

I have just added the password, but my entry/certificate does not have a key, could this be contributing to the error? How can I fix it?

推荐答案

令人惊讶的是，这可能意味着服务器无法找到私钥/证书对。在这种情况下，这是因为您没有通过 javax.net.ssl.keyStorePassword 指定密钥库密码。

Surprisingly, this can mean that the server couldn't find a private key/certificate pair. In this case it is because you haven't specified the keystore password via javax.net.ssl.keyStorePassword.
