==========
|
|
|
|
A framework for building Let's Encrypt v2 (ACME draft 11) clients, successor to `le-acme-core.js`.
|
|
Built [by request](https://git.coolaj86.com/coolaj86/greenlock.js/issues/5#issuecomment-8).

## How to build ACME clients
|
|
|
|
As this is intended to build ACME clients, there is not a simple 2-line example.
|
|
|
|
I'd recommend first running the example CLI client with a test domain and then investigating the files used for that example:
|
|
|
|
```bash
|
|
node examples/cli.js
|
|
```
|
|
|
|
The example cli has the following prompts:
|
|
|
|
```
|
|
What web address(es) would you like to get certificates for? (ex: example.com,*.example.com)
|
|
What challenge will you be testing today? http-01 or dns-01? [http-01]
|
|
What email should we use? (optional)
|
|
What API style would you like to test? v1-compat or promise? [v1-compat]
|
|
|
|
Put the string 'mBfh0SqaAV3MOK3B6cAhCbIReAyDuwuxlO1Sl70x6bM.VNAzCR4THe4czVzo9piNn73B1ZXRLaB2CESwJfKkvRM' into a file at 'example.com/.well-known/acme-challenge/mBfh0SqaAV3MOK3B6cAhCbIReAyDuwuxlO1Sl70x6bM'
|
|
|
|
echo 'mBfh0SqaAV3MOK3B6cAhCbIReAyDuwuxlO1Sl70x6bM.VNAzCR4THe4czVzo9piNn73B1ZXRLaB2CESwJfKkvRM' > 'example.com/.well-known/acme-challenge/mBfh0SqaAV3MOK3B6cAhCbIReAyDuwuxlO1Sl70x6bM'
|
|
|
|
Then hit the 'any' key to continue...
|
|
```
|
|
|
|
When you've completed the challenge you can hit a key to continue the process.
|
|
|
|
If you place the certificate you receive back in `tests/fullchain.pem`
|
|
you can then test it with `examples/https-server.js`.
|
|
|
|
```
|
|
examples/cli.js
|
|
examples/genkeypair.js
|
|
tests/compat.js
|
|
examples/https-server.js
|
|
examples/http-server.js
|
|
```
|
|
|
|
## Let's Encrypt Directory URLs
|
|
|
|
```
|
|
# Production URL
|
|
https://acme-v02.api.letsencrypt.org/directory
|
|
```
|
|
|
|
```
|
|
# Staging URL
|
|
https://acme-staging-v02.api.letsencrypt.org/directory
|
|
```
|
|
|
|
## Two API versions, Two Implementations
|
|
|
|
This library (acme-v2.js) supports ACME [*draft 11*](https://tools.ietf.org/html/draft-ietf-acme-acme-11),
|
|
otherwise known as Let's Encrypt v2 (or v02).
|
|
|
|
* ACME draft 11
|
|
* Let's Encrypt v2
|
|
* Let's Encrypt v02
|
|
|
|
The predecessor (le-acme-core) supports Let's Encrypt v1 (or v01), which was a
|
|
[hodge-podge of various drafts](https://github.com/letsencrypt/boulder/blob/master/docs/acme-divergences.md)
|
|
of the ACME spec early on.
|
|
|
|
* ACME early draft
|
|
* Let's Encrypt v1
|
|
* Let's Encrypt v01
|
|
|
|
This library maintains compatibility with le-acme-core so that it can be used as a **drop-in replacement**
|
|
and requires **no changes to existing code**,
|
|
but also provides an updated API more congruent with draft 11.
|
|
|
|
## le-acme-core-compatible API (recommended)
|
|
|
|
Status: Stable, Locked, Bugfix-only
|
|
|
|
See Full Documentation at <https://git.coolaj86.com/coolaj86/le-acme-core.js>
|
|
|
|
```
|
|
var RSA = require('rsa-compat').RSA;
|
|
var acme = require('acme-v2/compat.js').ACME.create({ RSA: RSA });
|
|
|
|
//
|
|
// Use exactly the same as le-acme-core
|
|
//
|
|
```
|
|
|
|
## Promise API (dev)
|
|
|
|
Status: Almost stable, but **not semver locked**
|
|
|
|
This API is a simple evolution of le-acme-core,
|
|
but tries to provide a better mapping to the new draft 11 APIs.
|
|
|
|
```
|
|
// Create Instance (Dependency Injection)
|
|
var ACME = require('acme-v2').ACME.create({
|
|
RSA: require('rsa-compat').RSA
|
|
|
|
// other overrides
|
|
, request: require('request')
|
|
, promisify: require('util').promisify
|
|
|
|
// used for constructing user-agent
|
|
, os: require('os')
|
|
, process: require('process')
|
|
|
|
// used for overriding the default user-agent
|
|
, userAgent: 'My custom UA String'
|
|
, getUserAgentString: function (deps) { return 'My custom UA String'; }
|
|
|
|
// don't try to validate challenges locally
|
|
, skipChallengeTest: false
|
|
});
|
|
|
|
|
|
// Discover Directory URLs
|
|
ACME.init(acmeDirectoryUrl) // returns Promise<acmeUrls={keyChange,meta,newAccount,newNonce,newOrder,revokeCert}>
|
|
|
|
|
|
// Accounts
|
|
ACME.accounts.create(options) // returns Promise<regr> registration data
|
|
|
|
{ email: '<email>' // valid email (server checks MX records)
|
|
, accountKeypair: { // privateKeyPem or privateKeyJwt
|
|
privateKeyPem: '<ASCII PEM>'
|
|
}
|
|
, agreeToTerms: fn (tosUrl) {} // returns Promise with tosUrl
|
|
}
|
|
|
|
|
|
// Registration
|
|
ACME.certificates.create(options) // returns Promise<pems={ privkey (key), cert, chain (ca) }>
|
|
|
|
{ newAuthzUrl: '<url>' // specify acmeUrls.newAuthz
|
|
, newCertUrl: '<url>' // specify acmeUrls.newCert
|
|
|
|
, domainKeypair: {
|
|
privateKeyPem: '<ASCII PEM>'
|
|
}
|
|
, accountKeypair: {
|
|
privateKeyPem: '<ASCII PEM>'
|
|
}
|
|
, domains: [ 'example.com' ]
|
|
|
|
, setChallenge: fn (hostname, key, val) // return Promise
|
|
, removeChallenge: fn (hostname, key) // return Promise
|
|
}
|
|
```
