https在Server端的Nodejs实现

服务器端利用Nodejs创建https的Server，请参考Nodejs创建HTTPS服务器

首先确保已经安装nodejs、nodejs-https组件和openssl。

用openssl生成密钥

cd到你的server路径。
生成私钥key文件privatekey.pem

openssl genrsa -out privatekey.pem 1024

通过私钥生成CSR证书签名

openssl req -new -key privatekey.pem -out certrequest.csr

填写一些证书信息：

You are about to be asked to enter information that will be incorporated into your certificate request.

What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter ‘.’, the field will be left blank.

Country Name (2 letter code) [AU]:CN
State or Province Name (full name) [Some-State]:Zhejiang
Locality Name (eg, city) []:Hangzhou
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Organization
Organizational Unit Name (eg, section) []:Organization
Common Name (eg, YOUR name) []:Name Zhang
Email Address []:Name@gmail.com

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

通过私钥和证书签名生成证书文件

openssl x509 -req -in certrequest.csr -signkey privatekey.pem -out certificate.pem

至此，我们有了三个文件：

privatekey.pem: 私钥
certrequest.csr: CSR证书签名
certificate.pem: 证书文件

实现服务器端app

var https = require('https')，
    fs = require("fs");

var options = {
    key: fs.readFileSync('./privatekey.pem'),
    cert: fs.readFileSync('./certificate.pem')
};

https.createServer(options, function(request, response) {
    response.writeHead(200);
    response.end("hello world\n");
}).listen(8181);
console.log('Https server listening on port ' + 8181);
