Node.js tlsSocket.getSharedSigalgs() 方法

tlsSocket.getSharedSigalgs()是 tls 模块中 TLSSocket 类的内置应用程序编程接口,用于返回服务器和客户端之间共享的签名算法数组。

句法:

const tlsSocket.getSharedSigalgs()

参数:此方法不接受任何参数。

返回值:该方法返回服务器和客户端共享的签名算法数组。

如何生成私钥和公共证书?

    现在将文件名保存为private-key.pem

  • 公共证书:打开记事本并复制粘贴以下密钥:

    -----END CERTIFICATE-----
    

    现在将文件名保存为public-cert.pem

示例 1:文件名:index.js

// Node.js program to demonstrate the
// tlsSocket.getSharedSigalgs() 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 array of signature
  // by using tlsSocket.getSharedSigalgs() method
  value = client.getSharedSigalgs();
  
  client.write("List of Signature Algorithm : " + value);
    
  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: List of Signature Algorithm :
Server closed successfully

示例 2:文件名:index.js

// Node.js program to demonstrate the
// tlsSocket.getSharedSigalgs() method
var tls = require('tls'),
    fs = require('fs'),
  
// Port and host address for server    
PORT = 1337,
HOST = '127.0.0.1';
   
// 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) {
  
  // Getting array of signature
  // by using tlsSocket.getSharedSigalgs() method
  value = socket.getSharedSigalgs();
  
  socket.write("Signature Algorithm : " + value[3]);
  
  // 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() {
   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: Signature Algorithm : Ed25519+UNDEF
client closed successfully
Server closed successfully
