1. 使用openssl生成服務器和客戶端證書
生成服務器證書，服務器使用自簽名證書（也就是自己扮演CA）
openssl genrsa -out server-key.pem 2048 openssl req -new -sha256 -key server-key.pem -out server-csr.pem //在CN處填寫服務器主機名www.qikangwei.com openssl x509 -req -in server-csr.pem -signkey server-key.pem -out server-cert.pem
將服務器私鑰server-key.pem和CA根證書server-cert.pem複製到客戶端，然後生成客戶端證書
openssl genrsa -out client-key.pem 2048 openssl req -new -sha256 -key client-key.pem -out client-csr.pem //在CN出填寫客戶端主機名 openssl x509 -req -CA server-cert.pem -CAkey server-key.pem -CAcreateserial -in client-csr.pem -out client-cert.pem
2. 創建服務器和客戶端腳本
服務器：
vi tls-server.js
var tls = require('tls');
var fs = require('fs');
var options = {
key: fs.readFileSync('server-key.pem'),
cert: fs.readFileSync('server-cert.pem'),
ca: [ fs.readFileSync('server-cert.pem') ],
requestCert: true,
rejectUnauthorized: true
};
var server = tls.createServer(options, function(test) {
console.log('server connected', test.authorized ? 'authorized' : 'unauthorized');
test.write("welcome!\n");
test.setEncoding('utf8');
test.on('data', function(data) {
console.log(data);
});
test.on('close', function() {
console.log('client has closed');
server.close();
});
});
server.listen(2345, function() {
console.log('server bound');
});客戶端：
vi tls-client.js
var tls = require('tls');
var fs = require('fs');
var options = {
host: 'www.qikangwei.com',
port: 2345,
key: fs.readFileSync('client-key.pem'),
cert: fs.readFileSync('client-cert.pem'),
ca: [ fs.readFileSync('server-cert.pem') ],
rejectUnauthorized: true
};
var client = tls.connect(options, function() {
console.log('client connected', client.authorized ? 'authorized' : 'unauthorized');
process.stdin.setEncoding('utf8');
process.stdin.on('readable', function() {
var chunk = process.stdin.read();
if (chunk !== null) {
client.write(chunk);
}
});
});
client.setEncoding('utf8');
client.on('data', function(data) {
console.log(data);
});
client.write("happy new year!");3. 測試
服務器：
node tls-server.js
客戶端：
node tls-client.js
腳本啓動後，在客戶端輸入內容，服務器端會顯示同樣的內容
