# Client certificate
|
|
|
|
Client certificate authentication can be configured with the `Client`, the required options are passed along through the `connect` option.
|
|
|
|
The client certificates must be signed by a trusted CA. The Node.js default is to trust the well-known CAs curated by Mozilla.
|
|
|
|
Setting the server option `requestCert: true` tells the server to request the client certificate.
|
|
|
|
The server option `rejectUnauthorized: false` allows us to handle any invalid certificate errors in client code. The `authorized` property on the socket of the incoming request will show if the client certificate was valid. The `authorizationError` property will give the reason if the certificate was not valid.
|
|
|
|
### Client Certificate Authentication
|
|
|
|
```js
|
|
const { readFileSync } = require('fs')
|
|
const { join } = require('path')
|
|
const { createServer } = require('https')
|
|
const { Client } = require('undici')
|
|
|
|
const serverOptions = {
|
|
ca: [
|
|
readFileSync(join(__dirname, 'client-ca-crt.pem'), 'utf8')
|
|
],
|
|
key: readFileSync(join(__dirname, 'server-key.pem'), 'utf8'),
|
|
cert: readFileSync(join(__dirname, 'server-crt.pem'), 'utf8'),
|
|
requestCert: true,
|
|
rejectUnauthorized: false
|
|
}
|
|
|
|
const server = createServer(serverOptions, (req, res) => {
|
|
// true if client cert is valid
|
|
if(req.client.authorized === true) {
|
|
console.log('valid')
|
|
} else {
|
|
console.error(req.client.authorizationError)
|
|
}
|
|
res.end()
|
|
})
|
|
|
|
server.listen(0, function () {
|
|
const tls = {
|
|
ca: [
|
|
readFileSync(join(__dirname, 'server-ca-crt.pem'), 'utf8')
|
|
],
|
|
key: readFileSync(join(__dirname, 'client-key.pem'), 'utf8'),
|
|
cert: readFileSync(join(__dirname, 'client-crt.pem'), 'utf8'),
|
|
rejectUnauthorized: false,
|
|
servername: 'agent1'
|
|
}
|
|
const client = new Client(`https://localhost:${server.address().port}`, {
|
|
connect: tls
|
|
})
|
|
|
|
client.request({
|
|
path: '/',
|
|
method: 'GET'
|
|
}, (err, { body }) => {
|
|
body.on('data', (buf) => {})
|
|
body.on('end', () => {
|
|
client.close()
|
|
server.close()
|
|
})
|
|
})
|
|
})
|
|
```
