更新（2018 年 11 月）：您需要自签名证书吗？
还是真正的证书可以更好地完成工作？你考虑过这些吗？
（注：Let's Encrypt 也可以向私有网络颁发证书）

完整的工作示例
- 创建证书
- 运行 node.js 服务器
- node.js 客户端中没有警告或错误
- cURL 中没有警告或错误
https://github.com/coolaj86/nodejs-self-signed-certificate-example
以localhost.greenlock.domains127.0.0.1 为例（它指向 127.0.0.1）：
服务器.js
'use strict';
var https = require('https')
, port = process.argv[2] || 8043
, fs = require('fs')
, path = require('path')
, server
, options
;
require('ssl-root-cas')
.inject()
.addFile(path.join(__dirname, 'server', 'my-private-root-ca.cert.pem'))
;
options = {
// this is ONLY the PRIVATE KEY
key: fs.readFileSync(path.join(__dirname, 'server', 'privkey.pem'))
// You DO NOT specify `ca`, that's only for peer authentication
//, ca: [ fs.readFileSync(path.join(__dirname, 'server', 'my-private-root-ca.cert.pem'))]
// This should contain both cert.pem AND chain.pem (in that order)
, cert: fs.readFileSync(path.join(__dirname, 'server', 'fullchain.pem'))
};
function app(req, res) {
res.setHeader('Content-Type', 'text/plain');
res.end('Hello, encrypted world!');
}
server = https.createServer(options, app).listen(port, function () {
port = server.address().port;
console.log('Listening on https://127.0.0.1:' + port);
console.log('Listening on https://' + server.address().address + ':' + port);
console.log('Listening on https://localhost.greenlock.domains:' + port);
});
客户端.js
'use strict';
var https = require('https')
, fs = require('fs')
, path = require('path')
, ca = fs.readFileSync(path.join(__dirname, 'client', 'my-private-root-ca.cert.pem'))
, port = process.argv[2] || 8043
, hostname = process.argv[3] || 'localhost.greenlock.domains'
;
var options = {
host: hostname
, port: port
, path: '/'
, ca: ca
};
options.agent = new https.Agent(options);
https.request(options, function(res) {
res.pipe(process.stdout);
}).end();
以及制作证书文件的脚本：
制作证书.sh
#!/bin/bash
FQDN=$1
# make directories to work from
mkdir -p server/ client/ all/
# Create your very own Root Certificate Authority
openssl genrsa \
-out all/my-private-root-ca.privkey.pem \
2048
# Self-sign your Root Certificate Authority
# Since this is private, the details can be as bogus as you like
openssl req \
-x509 \
-new \
-nodes \
-key all/my-private-root-ca.privkey.pem \
-days 1024 \
-out all/my-private-root-ca.cert.pem \
-subj "/C=US/ST=Utah/L=Provo/O=ACME Signing Authority Inc/CN=example.com"
# Create a Device Certificate for each domain,
# such as example.com, *.example.com, awesome.example.com
# NOTE: You MUST match CN to the domain name or ip address you want to use
openssl genrsa \
-out all/privkey.pem \
2048
# Create a request from your Device, which your Root CA will sign
openssl req -new \
-key all/privkey.pem \
-out all/csr.pem \
-subj "/C=US/ST=Utah/L=Provo/O=ACME Tech Inc/CN=${FQDN}"
# Sign the request from Device with your Root CA
openssl x509 \
-req -in all/csr.pem \
-CA all/my-private-root-ca.cert.pem \
-CAkey all/my-private-root-ca.privkey.pem \
-CAcreateserial \
-out all/cert.pem \
-days 500
# Put things in their proper place
rsync -a all/{privkey,cert}.pem server/
cat all/cert.pem > server/fullchain.pem # we have no intermediates in this case
rsync -a all/my-private-root-ca.cert.pem server/
rsync -a all/my-private-root-ca.cert.pem client/
# create DER format crt for iOS Mobile Safari, etc
openssl x509 -outform der -in all/my-private-root-ca.cert.pem -out client/my-private-root-ca.crt
例如：
bash make-certs.sh 'localhost.greenlock.domains'
希望这能把钉子钉在棺材上。

在 iOS Mobile Safari 上安装私有证书
您需要创建一个带有 .crt 扩展名的 DER 格式的根 ca 证书的副本：
# create DER format crt for iOS Mobile Safari, etc
openssl x509 -outform der -in all/my-private-root-ca.cert.pem -out client/my-private-root-ca.crt
然后，您可以简单地使用您的网络服务器提供该文件。当您单击该链接时，系统会询问您是否要安装证书。
有关其工作原理的示例，您可以尝试安装 MIT 的证书颁发机构：https ://ca.mit.edu/mitca.crt
