letsencrypt
===========
Automatic [Let's Encrypt](https://letsencrypt.org) HTTPS / TLS / SSL Certificates for node.js
Free SLL with [90-day](https://letsencrypt.org/2015/11/09/why-90-days.html) HTTPS / TLS Certificates
Are these the droids you're looking for?
------
This is a **low-level library** for implementing ACME / LetsEncrypt Clients, CLIs,
system tools, and abstracting storage backends (file vs db, etc).
For `express`, raw `https` or `spdy`, or `restify` (same as raw https) see
[**letsencrypt-express**](https://github.com/Daplie/letsencrypt-express).
For `hapi` see [letsencrypt-hapi](https://github.com/Daplie/letsencrypt-hapi).
For `koa` or `rill`
see [letsencrypt-koa](https://github.com/Daplie/letsencrypt-koa).
For `bash`, `fish`, `zsh`, `cmd.exe`, `PowerShell`
see [**letsencrypt-cli**](https://github.com/Daplie/letsencrypt-cli).
Install
=======
`letsencrypt` requires at least two plugins:
one for managing certificate storage and the other for handling ACME challenges.
The default storage plugin is [`le-store-certbot`](https://github.com/Daplie/le-store-certbot)
and the default challenge is [`le-challenge-fs`](https://github.com/Daplie/le-challenge-fs).
```bash
npm install --save letsencrypt@2.x
npm install --save le-store-certbot@2.x # default plugin for accounts, certificates, and keypairs
npm install --save le-challenge-fs@2.x # default plugin for challenge handlers
npm install --save le-acme-core@2.x # default plugin for ACME spec
npm install --save le-sni-auto@2.x # default plugin for SNICallback
```
Usage
=====
It's very simple and easy to use, but also very complete and easy to extend and customize.
### Overly Simplified Example
Against my better judgement I'm providing a terribly oversimplified example
of how to use this library:
```javascript
var le = require('letsencrypt').create({ server: 'staging' });
var opts = {
domains: ['example.com'], email: 'user@email.com', agreeTos: true
};
le.register(opts).then(function (certs) {
console.log(certs);
// privkey, cert, chain, expiresAt, issuedAt, subject, altnames
}, function (err) {
console.error(err);
});
```
You also need some sort of server to handle the acme challenge:
```javascript
var app = express();
app.use('/', le.middleware());
```
Note: The `webrootPath` string is a template.
Any occurance of `:hostname` will be replaced
with the domain for which we are requested certificates.
### Useful Example
The configuration consists of 3 components:
* Storage Backend (search npm for projects starting with 'le-store-')
* ACME Challenge Handlers (search npm for projects starting with 'le-challenge-')
* Letsencryt Config (this is all you)
```javascript
'use strict';
var LE = require('letsencrypt');
var le;
// Storage Backend
var leStore = require('le-store-certbot').create({
configDir: '~/letsencrypt/etc' // or /etc/letsencrypt or wherever
, debug: false
});
// ACME Challenge Handlers
var leChallenge = require('le-challenge-fs').create({
webrootPath: '~/letsencrypt/var/' // or template string such as
, debug: false // '/srv/www/:hostname/.well-known/acme-challenge'
});
function leAgree(opts, agreeCb) {
// opts = { email, domains, tosUrl }
agreeCb(null, opts.tosUrl);
}
le = LE.create({
server: LE.stagingServerUrl // or LE.productionServerUrl
, store: leStore // handles saving of config, accounts, and certificates
, challenge: leChallenge // handles /.well-known/acme-challege keys and tokens
, agreeToTerms: leAgree // hook to allow user to view and accept LE TOS
, debug: false
});
// If using express you should use the middleware
// app.use('/', le.middleware());
//
// Otherwise you should see the test file for usage of this:
// le.challenge.get(opts.domain, key, val, done)
// Check in-memory cache of certificates for the named domain
le.check({ domains: [ 'example.com' ] }).then(function (results) {
if (results) {
// we already have certificates
return;
}
// Register Certificate manually
le.register({
domains: ['example.com'] // CHANGE TO YOUR DOMAIN (list for SANS)
, email: 'user@email.com' // CHANGE TO YOUR EMAIL
, agreeTos: '' // set to tosUrl string (or true) to pre-approve (and skip agreeToTerms)
, rsaKeySize: 2048 // 2048 or higher
, challengeType: 'http-01' // http-01, tls-sni-01, or dns-01
}).then(function (results) {
console.log('success');
}, function (err) {
// Note: you must either use le.middleware() with express,
// manually use le.challenge.get(opts, domain, key, val, done)
// or have a webserver running and responding
// to /.well-known/acme-challenge at `webrootPath`
console.error('[Error]: node-letsencrypt/examples/standalone');
console.error(err.stack);
});
});
```
Here's what `results` looks like:
```javascript
{ privkey: '' // PEM encoded private key
, cert: '' // PEM encoded cert
, chain: '' // PEM encoded intermediate cert
, issuedAt: 0 // notBefore date (in ms) parsed from cert
, expiresAt: 0 // notAfter date (in ms) parsed from cert
, subject: '' // example.com
, altnames: [] // example.com,www.example.com
}
```
API
---
The full end-user API is exposed in the example above and includes all relevant options.
```
le.register(opts)
le.check(opts)
```
### Helper Functions
We do expose a few helper functions:
* LE.validDomain(hostname) // returns '' or the hostname string if it's a valid ascii or punycode domain name
TODO fetch domain tld list
### Template Strings
The following variables will be tempalted in any strings passed to the options object:
* `~/` replaced with `os.homedir()` i.e. `/Users/aj`
* `:hostname` replaced with the first domain in the list i.e. `example.com`
Developer API
-------------
If you are developing an `le-store-*` or `le-challenge-*` plugin you need to be aware of
additional internal API expectations.
**IMPORTANT**:
Use `v2.0.0` as your initial version - NOT v0.1.0 and NOT v1.0.0 and NOT v3.0.0.
This is to indicate that your module is compatible with v2.x of node-letsencrypt.
Since the public API for your module is defined by node-letsencrypt the major version
should be kept in sync.
### store implementation
See https://github.com/Daplie/node-letsencrypt/issues/39 and https://github.com/Daplie/le-store-certbot
* getOptions()
* accounts.
* checkKeypair(opts, cb)
* check(opts, cb)
* setKeypair(opts, keypair, cb)
* set(opts, reg, cb)
* certificates.
* checkKeypair(opts, cb)
* check(opts, cb)
* setKeypair(opts, keypair, cb)
* set(opts, reg, cb)
### challenge implementation
See https://github.com/Daplie/le-challenge-fs
* `.set(opts, domain, key, value, cb);` // opts will be saved with domain/key
* `.get(opts, domain, key, cb);` // opts will be retrieved by domain/key
* `.remove(opts, domain, key, cb);` // opts will be retrieved by domain/key
