如何生成私钥和公钥证书？

• Private Key
  Step 1: Open notepad and copy paste the following key:

  js
-----BEGIN RSA PRIVATE KEY-----

  步骤 2: 另存为私钥. pem




• Public Certificate
  Step 1: Open notepad and copy paste the following key:

  js

  步骤 2: 另存为公共证书

示例 1: 文件名:index.js

// Node.js program to demonstrate the
// tlsSocket.getCertificate() method
var tls = require('tls'),
    fs = require('fs'),
    // Port and host address for server    
    PORT = 1337,
    HOST = '127.0.0.1',
    value = null;
// Private key and public certificate for access
var optiOns= {
    key: fs.readFileSync('private-key.pem'),
    cert: fs.readFileSync('public-cert.pem'),
    rejectUnauthorized: false
};
// Creating and initializing server
var server = tls.createServer(options,
    function (socket) {
        // Print the data that we received
        socket.on('data', function (data) {
            console.log('\nReceived: %s ',
                data.toString().replace(/(\n)/gm, ""));
        });
        // Stopping the server
        // by using the close() method
        server.close(() => {
            console.log("Server closed successfully");
        });
    });
// Start listening on a specific port and address
// by using listen() method
server.listen(PORT, HOST, function () {
    console.log("I'm listening at %s, "
        + "on port %s", HOST, PORT);
});
// Creating and initializing client
var client = tls.connect(PORT, HOST,
    options, function () {
        // Getting local certificate by using
        // tlsSocket.getCertificate() method
        value = client.getCertificate();
        client.write("Certificate : " + value.serialNumber);
        client.end(() => {
            console.log("Client closed successfully");
        });
    });


使用以下命令运行 index.js 文件:

node index.js


输出:

I'm listening at 127.0.0.1, on port 1337
Client closed successfully
Received: Certificate : F1C5E5F0F75E18D8
Server closed successfully


示例 2: 文件名:index.js

        server.close(() => {

        });
    });
// Start listening on a specific port

server.listen(PORT, HOST, function () {
    console.log("I'm listening at %s, "
        + "on port %s", HOST, PORT);
});
// Creating and initializing client
var client = tls.connect(PORT, HOST,
    options, function () {
        console.log("client is connected");
    });
client.on("data", function (data) {
    console.log('Received: %s',
        data.toString().replace(/(\n)/gm, ""));
    // Close the connection after 
    // receiving the message
    client.end(() => {
        console.log("client closed successfully")
    });
});


使用以下命令运行 index.js 文件:

node index.js


输出:

I'm listening at 127.0.0.1, on port 1337
client is connected
Received: Certificate : F1C5E5F0F75E18D8
client closed successfully
Server closed successfully
