用Node.js创建自签名的HTTPS服务器

1. 创建自己的CA机构
2. 创建服务器端证书
3. 创建客户端证书
4. 将证书打包

创建自己的CA机构

• 为CA生成私钥

openssl genrsa -out ca-key.pem -des 1024

• 通过CA私钥生成CSR

openssl req -new -key ca-key.pem -out ca-csr.pem

• 通过CSR文件和私钥生成CA证书

openssl x509 -req -in ca-csr.pem -signkey ca-key.pem -out ca-cert.pem

可能会遇到的问题

你需要root或者admin的权限Unable to load config info from /user/local/ssl/openssl.cnf对于这个问题，你可以从网上下载一份正确的openssl.cnf文件，然后set OPENSSL_CONF=openssl.cnf文件的本地路径

创建服务器端证书

• 为服务器生成私钥

openssl genrsa -out server-key.pem 1024

• 利用服务器私钥文件服务器生成CSR

openssl req -new -key server-key.pem -config openssl.cnf -out server-csr.pem

这一步非常关键，你需要指定一份openssl.cnf文件。可以用这个

[req]      distinguished_name = req_distinguished_name      req_extensions = v3_req        [req_distinguished_name]      countryName = Country Name (2 letter code)      countryName_default = CN      stateOrProvinceName = State or Province Name (full name)      stateOrProvinceName_default = BeiJing      localityName = Locality Name (eg, city)      localityName_default = YaYunCun      organizationalUnitName  = Organizational Unit Name (eg, section)      organizationalUnitName_default  = Domain Control Validated      commonName = Internet Widgits Ltd      commonName_max  = 64        [ v3_req ]      # Extensions to add to a certificate request      basicConstraints = CA:FALSE      keyUsage = nonRepudiation, digitalSignature, keyEncipherment      subjectAltName = @alt_names        [alt_names]  	#注意这个IP.1的设置，IP地址需要和你的服务器的监听地址一样    IP.1 = 127.0.0.1

• 通过服务器私钥文件和CSR文件生成服务器证书

openssl x509 -req -CA ca-cert.pem -CAkey ca-key.pem -CAcreateserial -in server-csr.pem -out server-cert.pem -extensions v3_req -extfile openssl.cnf

创建客户端证书

• 生成客户端私钥

openssl genrsa -out client-key.pem

• 利用私钥生成CSR

openssl req -new -key client-key.pem -out client-csr.pem

• 生成客户端证书

openssl x509 -req -CA ca-cert.pem -CAkey ca-key.pem -CAcreateserial -in client-csr.pem -out client-cert.pem

HTTPS 服务器代码

var https = require('https');var fs = require('fs');var options = {
   	key: fs.readFileSync('./keys/server-key.pem'),	ca: [fs.readFileSync('./keys/ca-cert.pem')],	cert: fs.readFileSync('./keys/server-cert.pem')};https.createServer(options,function(req,res){
   	res.writeHead(200);	res.end('hello world\n');}).listen(3000,'127.0.0.1');

HTTPS 客户端代码

var https = require('https');var fs = require('fs');var options = {
   	hostname:'127.0.0.1',	port:3000,	path:'/',	method:'GET',	key:fs.readFileSync('./keys/client-key.pem'),	cert:fs.readFileSync('./keys/client-cert.pem'),	ca: [fs.readFileSync('./keys/ca-cert.pem')],	agent:false};options.agent = new https.Agent(options);var req = https.request(options,function(res){
   console.log("statusCode: ", res.statusCode);  console.log("headers: ", res.headers);	res.setEncoding('utf-8');	res.on('data',function(d){
   		console.log(d);	})});req.end();req.on('error',function(e){
   	console.log(e);})

将证书打包

• 打包服务器端证书

openssl pkcs12 -export -in server-cert.pem -inkey server-key.pem -certfile ca-cert.pem -out server.pfx

• 打包客户端证书

openssl pkcs12 -export -in client-cert.pem -inkey client-key.pem -certfile ca-cert.pem -out client.pfx

服务器端代码

var https = require('https');var fs = require('fs');var options = {
   	pfx:fs.readFileSync('./keys/server.pfx'),	passphrase:'your password'};https.createServer(options,function(req,res){
   	res.writeHead(200);	res.end('hello world\n');}).listen(3000,'127.0.0.1');

客户端代码

var https = require('https');var fs = require('fs');var options = {
   	hostname:'127.0.0.1',	port:3000,	path:'/',	method:'GET',	pfx:fs.readFileSync('./keys/server.pfx'),	passphrase:'your password',	agent:false};options.agent = new https.Agent(options);var req = https.request(options,function(res){
   console.log("statusCode: ", res.statusCode);  console.log("headers: ", res.headers);	res.setEncoding('utf-8');	res.on('data',function(d){
   		console.log(d);	})});req.end();req.on('error',function(e){
   	console.log(e);})
