+| A [Root](https://therootcompany.com) Project

-## Automated Certificate Management Environment
+# [acme-v2.js](https://git.coolaj86.com/coolaj86/acme-v2.js)

-ACME ([RFC 8555](https://tools.ietf.org/html/rfc8555)) is the protocol that powers **Let's Encrypt**.
+A lightweight, **Low Dependency**&#42; framework for building
+Let's Encrypt v2 (ACME draft 12) clients, successor to `le-acme-core.js`.
+Built [by request](https://git.coolaj86.com/coolaj86/greenlock.js/issues/5#issuecomment-8).

-ACME.js is a _low-level_ client that speaks RFC 8555 to get Free SSL certificates through Let's Encrypt.
+&#42; <small>although `node-forge` and `ursa` are included as `optionalDependencies`
+for backwards compatibility with older versions of node, there are no other
+dependencies except those that I wrote for this (and related) projects.</small>

-Looking for an **easy**, _high-level_ client? Check out [Greenlock.js](https://git.rootprojects.org/root/greenlock.js).
+## Looking for Quick 'n' Easy&trade;?

-# Quick Start
+If you're looking to *build a webserver*, try [greenlock.js](https://git.coolaj86.com/coolaj86/greenlock.js).
+If you're looking for an *ACME-enabled webserver*, try [goldilocks.js](https://git.coolaj86.com/coolaj86/goldilocks.js).

-```js
-var acme = ACME.create({ maintainerEmail, packageAgent, notify });
-await acme.init(directoryUrl);
+* [greenlock.js](https://git.coolaj86.com/coolaj86/greenlock.js)
+* [goldilocks.js](https://git.coolaj86.com/coolaj86/goldilocks.js)

-// Create Let's Encrypt Account
-var accountOptions = { subscriberEmail, agreeToTerms, accountKey };
-var account = await acme.accounts.create(accountOptions);
+## How to build ACME clients

-// Validate Domains
-var certificateOptions = { account, accountKey, csr, domains, challenges };
-var pems = await acme.certificates.create(certificateOptions);
+As this is intended to build ACME clients, there is not a simple 2-line example
+(and if you want that, see [greenlock-express.js](https://git.coolaj86.com/coolaj86/greenlock-express.js)).

-// Get SSL Certificate
-var fullchain = pems.cert + '\n' + pems.chain + '\n';
-await fs.promises.writeFile('fullchain.pem', fullchain, 'ascii');
+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
 ```

-# Online Demo
+The example cli has the following prompts:

-See https://greenlock.domains
+```
+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'

-We expect that our hosted versions will meet all of yours needs.
-If they don't, please open an issue to let us know why.

-We'd much rather improve the app than have a hundred different versions running in the wild.
-However, in keeping to our values we've made the source visible for others to inspect, improve, and modify.
+Then hit the 'any' key to continue...
+```

-->
+When you've completed the challenge you can hit a key to continue the process.

-# Features
+If you place the certificate you receive back in `tests/fullchain.pem`
+you can then test it with `examples/https-server.js`.

-# Use Cases
+## Two API versions, Two Implementations

-   Home Servers
-   IoT
-   Enterprise On-Prem
-   Web Hosting
-   Cloud Services
-   Localhost Development
+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).

-# API
+  * ACME draft 11
+  * Let's Encrypt v2
+  * Let's Encrypt v02

-The public API encapsulates the three high-level steps of the ACME protocol:
+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.

-1. API Discovery
-2. Account Creation
-    - Subscriber Agreement
-3. Certificate Issuance
-    - Certificate Request
-    - Authorization Challenges
-    - Challenge Presentation
-    - Certificate Redemption
+  * ACME early draft
+  * Let's Encrypt v1
+  * Let's Encrypt v01

-## API Overview
+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.

-The core API can be show in just four functions:
+## le-acme-core-compatible API (recommended)

-```js
-ACME.create({ maintainerEmail, packageAgent, notify });
-acme.init(directoryUrl);
-acme.accounts.create({ subscriberEmail, agreeToTerms, accountKey });
-acme.certificates.create({
-	customerEmail, // do not use
-	account,
-	accountKey,
-	csr,
-	domains,
-	challenges
+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
+  // ask if the certificate can be issued up to 10 times before failing
+, retryPoll: 8
+  // ask if the certificate has been validated up to 6 times before cancelling
+, retryPending: 4
+  // Wait 1000ms between retries
+, retryInterval: 1000
+  // Wait 10,000ms after deauthorizing a challenge before retrying
+, deauthWait: 10 * 1000
 });
+
+
+// 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

-
-**Maintainer vs Subscriber vs Customer**
-
-   `maintainerEmail` should be the email address of the **author of the code**.
-    This person will receive critical security and API change notifications.
-   `subscriberEmail` should be the email of the **admin of the hosting service**.
-    This person agrees to the Let's Encrypt Terms of Service and will be notified
-    when a certificate fails to renew.
-   `customerEmail` should be the email of individual who owns the domain.
-    This is optional (not currently implemented).
-
-Generally speaking **YOU** are the _maintainer_ and you **or your employer** is the _subscriber_.
-
-If you (or your employer) is running any type of service
-you **SHOULD NOT** pass the _customer_ email as the subscriber email.
-
-If you are not running a service (you may be building a CLI, for example),
-then you should prompt the user for their email address, and they are the subscriber.
-
-## Events
-
-These `notify` events are intended for _logging_ and debugging, NOT as a data API.
-
-| Event Name           | Example Message                                                                   |
-| -------------------- | --------------------------------------------------------------------------------- |
-| `certificate_order`  | `{ subject: 'example.com', altnames: ['...'], account: { key: { kid: '...' } } }` |
-| `challenge_select`   | `{ altname: '*.example.com', type: 'dns-01' }`                                    |
-| `challenge_status`   | `{ altname: '*.example.com', type: 'dns-01', status: 'pending' }`                 |
-| `challenge_remove`   | `{ altname: '*.example.com', type: 'dns-01' }`                                    |
-| `certificate_status` | `{ subject: 'example.com', status: 'valid' }`                                     |
-| `warning`            | `{ message: 'what went wrong', description: 'what action to take about it' }`     |
-| `error`              | `{ message: 'a background process failed, and it may have side-effects' }`        |
-
-Note: DO NOT rely on **undocumented properties**. They are experimental and **will break**.
-If you have a use case for a particular property **open an issue** - we can lock it down and document it.

-# Example (Full Walkthrough)
-
-### See [examples/README.md](https://git.rootprojects.org/root/acme.js/src/branch/master/examples/README.md)
-
-A basic example includes the following:
-
-1. Initialization
-    - maintainer contact
-    - package user-agent
-    - log events
-2. Discover API
-    - retrieves Terms of Service and API endpoints
-3. Get Subscriber Account
-    - create an ECDSA (or RSA) Account key in JWK format
-    - agree to terms
-    - register account by the key
-4. Prepare a Certificate Signing Request
-    - create a RSA (or ECDSA) Server key in PEM format
-    - select domains
-    - choose challenges
-    - sign CSR
-    - order certificate
-
-[examples/README.md](https://git.rootprojects.org/root/acme.js/src/branch/master/examples/README.md)
-covers all of these steps, with comments.

-
-The `http-01` plugin is similar, but without `zones` or `propagationDelay`.
-
-Many challenge plugins are already available for popular platforms.
-
-Search `acme-http-01-` or `acme-dns-01-` on npm to find more.

-# Running the Tests
-
-```bash
-npm test
-```
-
-## Usa a dns-01 challenge
-
-Although you can run the tests from a public facing server, its easiest to do so using a dns-01 challenge.
-
-You will need to use one of the [`acme-dns-01-*` plugins](https://www.npmjs.com/search?q=acme-dns-01-)
-to run the test locally.
-
-```bash
-ENV=DEV
-MAINTAINER_EMAIL=letsencrypt+staging@example.com
-SUBSCRIBER_EMAIL=letsencrypt+staging@example.com
-BASE_DOMAIN=test.example.com
-CHALLENGE_TYPE=dns-01
-CHALLENGE_PLUGIN=acme-dns-01-digitalocean
-CHALLENGE_OPTIONS='{"token":"xxxxxxxxxxxx"}'
-```
-
-### For Example
-
-```bash
-# Get the repo and change directories into it
-git clone https://git.rootprojects.org/root/acme.js
-pushd acme.js/
-
-# Install the challenge plugin you'll use for the tests
-npm install --save-dev acme-dns-01-digitalocean
-```
-
-## Create a `.env` config
-
-You'll need a `.env` in the project root that looks something like the one in `examples/example.env`:
-
-```bash
-# Copy the sample .env file
-rsync -av examples/example.env .env
-
-# Edit the config file to use a domain in your account, and your API token
-#vim .env
-code .env
-
-# Run the tests
-node tests/index.js
-```

-The rule of thumb is "attribute, but don't confuse". For example:
-
-> Built with [ACME.js](https://git.rootprojects.org/root/acme.js) (a [Root](https://rootprojects.org) project).

-# Example [ACME.js](https://git.rootprojects.org/root/acme.js) Usage
-
-| Built by [Root](https://therootcompany.com) for [Hub](https://rootprojects.org/hub)
-
-ACME.js is a _low-level_ client for Let's Encrypt.
-
-Looking for an **easy**, _high-level_ client? Check out [Greenlock.js](https://git.rootprojects.org/root/greenlock.js).
-
-# Overview
-
-A basic example includes the following:
-
-1. Initialization
-    - maintainer contact
-    - package user-agent
-    - log events
-2. Discover API
-    - retrieves Terms of Service and API endpoints
-3. Get Subscriber Account
-    - create an ECDSA (or RSA) Account key in JWK format
-    - agree to terms
-    - register account by the key
-4. Prepare a Certificate Signing Request
-    - create a RSA (or ECDSA) Server key in PEM format
-    - select domains (as punycode)
-    - choose challenges
-    - sign CSR
-    - order certificate
-
-# Code
-
-The tested-working code for this is in [examples/get-certificate-full.js](https://git.rootprojects.org/root/acme.js/src/branch/master/examples/get-certificate-full.js)
-
-# Walkthrough
-
-Whereas [Greenlock.js](https://git.rootprojects.org/root/greenlock.js) is very much "batteries included",
-the goal of ACME.js is to be lightweight and over more control.
-
-## 1. Create an `acme` instance
-
-The maintainer contact is used by Root to notify you of security notices and
-bugfixes to ACME.js.
-
-The subscriber contact is used by Let's Encrypt to manage your account and
-notify you of renewal failures. In the future we plan to enable some of that,
-but allowing for your own branding.
-
-The customer email is provided as an example of what NOT to use as either of the other two.
-Typically your customers are NOT directly Let's Encrypt subscribers.
-
-```js
-// In many cases all three of these are the same (your email)
-// However, this is what they may look like when different:
-
-var maintainerEmail = 'security@devshop.com';
-var subscriberEmail = 'support@hostingcompany.com';
-var customerEmail = 'jane.doe@gmail.com';
-```
-
-The ACME spec requires clients to have RFC 7231 style User Agent.
-This will be contstructed automatically using your package name.
-
-```js
-var pkg = require('../package.json');
-var packageAgent = 'test-' + pkg.name + '/' + pkg.version;
-```
-
-Set up your logging facility. It's fine to ignore the logs,
-but you'll probably want to log `warning` and `error` at least.
-
-```js
-// This is intended to get at important messages without
-// having to use even lower-level APIs in the code
-
-function notify(ev, msg) {
-    	if ('error' === ev || 'warning' === ev) {
-    		errors.push(ev.toUpperCase() + ' ' + msg.message);
-    		return;
-    	}
-    	// be brief on all others
-    	console.log(ev, msg.altname || '', msg.status || ''');
-}
-```
-
-```js
-var ACME = require('acme');
-var acme = ACME.create({ maintainerEmail, packageAgent, notify });
-```
-
-## 2. Fetch the API Directory
-
-ACME defines an API discovery mechanism.
-
-For Let's Encrypt specifically, these are the _production_ and _staging_ URLs:
-
-```js
-// Choose either the production or staging URL
-
-var directoryUrl = 'https://acme-staging-v02.api.letsencrypt.org/directory';
-//var directoryUrl = 'https://acme-v02.api.letsencrypt.org/directory'
-```
-
-The init function will fetch the API and set internal urls and such accordingly.
-
-```js
-await acme.init(directoryUrl);
-```
-
-## 3. Create (or import) an Account Keypair
-
-You must create a Subscriber Account using a public/private keypair.
-
-The Account key MUST be different from the server key.
-
-Keypairs.js will use native node crypto or WebCrypto to generate the key, and a lightweight parser and packer to translate between formats.
-
-```js
-var Keypairs = require('@root/keypairs');
-```
-
-Unless you're multi-tenanted, you only ever need ONE account key. Save it.
-
-```js
-// You only need ONE account key, ever, in most cases
-// save this and keep it safe. ECDSA is preferred.
-
-var accountKeypair = await Keypairs.generate({ kty: 'EC', format: 'jwk' });
-var accountKey = accountKeypair.private;
-```
-
-If you already have a key you would like to use, you can import it (as shown in the server key section below).
-
-## 4. Create an ACME Subscriber Account
-
-In order to use Let's Encrypt and ACME.js, you must agree to the respective Subscriber Agreement and Terms.
-
-```js
-// This can be `true` or an async function which presents the terms of use
-
-var agreeToTerms = true;
-
-// If you are multi-tenanted or white-labled and need to present the terms of
-// use to the Subscriber running the service, you can do so with a function.
-
-var agreeToTerms = async function() {
-	return true;
-};
-```
-
-You create an account with a signed JWS message including your public key, which ACME.js handles for you with your account key.
-
-All messages must be signed with your account key.
-
-```js
-console.info('registering new ACME account...');
-
-var account = await acme.accounts.create({
-	subscriberEmail,
-	agreeToTerms,
-	accountKey
-});
-console.info('created account with id', account.key.kid);
-```
-
-## 5. Create (or import) a Server Keypair
-
-You must have a SERVER keypair, which is different from your account keypair.
-
-This isn't part of the ACME protocol, but rather something your Web Server uses and which you must use to sign the request for an SSL certificate, the same as with paid issuers in the days of yore.
-
-In many situations you only ever need ONE of these.
-
-```js
-// This is the key used by your WEBSERVER, typically named `privkey.pem`,
-// `key.crt`, or `bundle.pem`. RSA may be preferrable for legacy compatibility.
-
-// You can generate it fresh
-var serverKeypair = await Keypairs.generate({ kty: 'RSA', format: 'jwk' });
-var serverKey = serverKeypair.private;
-var serverPem = await Keypairs.export({ jwk: serverKey });
-await fs.promises.writeFile('./privkey.pem', serverPem, 'ascii');
-
-// Or you can load it from a file
-var serverPem = await fs.promises.readFile('./privkey.pem', 'ascii');
-console.info('wrote ./privkey.pem');
-
-var serverKey = await Keypairs.import({ pem: serverPem });
-```
-
-## 6. Create a Signed Certificate Request (CSR)
-
-Your domains must be `punycode`-encoded:
-
-```js
-var punycode = require('punycode');
-
-var domains = ['example.com', '*.example.com', '你好.example.com'];
-domains = domains.map(function(name) {
-	return punycode.toASCII(name);
-});
-```
-
-```js
-var CSR = require('@root/csr');
-var PEM = require('@root/pem');
-
-var encoding = 'der';
-var typ = 'CERTIFICATE REQUEST';
-
-var csrDer = await CSR.csr({ jwk: serverKey, domains, encoding });
-var csr = PEM.packBlock({ type: typ, bytes: csrDer });
-```
-
-## 7. Choose Domain Validation Strategies
-
-You can use one of the existing http-01 or dns-01 plugins, or you can build your own.
-
-There's a test suite that makes this very easy to do:
-
-   [acme-dns-01-test](https://git.rootprojects.org/root/acme-dns-01-test.js)
-   [acme-http-01-test](https://git.rootprojects.org/root/acme-http-01-test.js)
-
-```js
-// You can pick from existing challenge modules
-// which integrate with a variety of popular services
-// or you can create your own.
-//
-// The order of priority will be http-01, tls-alpn-01, dns-01
-// dns-01 will always be used for wildcards
-// dns-01 should be the only option given for local/private domains
-
-var webroot = require('acme-http-01-webroot').create({});
-var challenges = {
-	'http-01': webroot,
-	'dns-01': {
-		init: async function(deps) {
-			// includes the http request object to use
-		},
-		zones: async function(args) {
-			// return a list of zones
-		},
-		set: async function(args) {
-			// set a TXT record with the lowest allowable TTL
-		},
-		get: async function(args) {
-			// check the TXT record exists
-		},
-		remove: async function(args) {
-			// remove the TXT record
-		},
-		// how long to wait after *all* TXTs are set
-		// before presenting them for validation
-		// (for most this is seconds, for some it may be minutes)
-		propagationDelay: 5000
-	}
-};
-```
-
-## 8. Verify Domains & Get an SSL Certificate
-
-```js
-console.info('validating domain authorization for ' + domains.join(' '));
-var pems = await acme.certificates.create({
-	account,
-	accountKey,
-	csr,
-	domains,
-	challenges
-});
-```
-
-## 9. Save the Certificate
-
-```js
-var fullchain = pems.cert + '\n' + pems.chain + '\n';
-
-await fs.promises.writeFile('fullchain.pem', fullchain, 'ascii');
-console.info('wrote ./fullchain.pem');
-```
-
-## 10. Test Drive Your Cert
-
-```js
-'use strict';
-
-var https = require('http2');
-var fs = require('fs');
-
-var key = fs.readFileSync('./privkey.pem');
-var cert = fs.readFileSync('./fullchain.pem');
-
-var server = https.createSecureServer({ key, cert }, function(req, res) {
-	res.end('Hello, Encrypted World!');
-});
-
-server.listen(443, function() {
-	console.info('Listening on', server.address());
-});
-```
-
-Note: You can allow non-root `node` processes to bind to port 443 using `setcap`:
-
-```bash
-sudo setcap 'cap_net_bind_service=+ep' $(which node)
-```
-
-You can also set your domain to localhost by editing your `/etc/hosts`:
-
-`/etc/hosts`:
-
-```txt
-127.0.0.1 test.example.com
-
-127.0.0.1	localhost
-255.255.255.255	broadcasthost
-::1             localhost
-```
