# Do you rely on ACME.js?
Hey! Let's Encrypt will **STOP WORKING** with Greenlock and ACME.js at the end of Oct 2019.
**WITHOUT YOUR HELP** we won't get the next release out in time.
If Greenlock (or ACME.js) has saved you time and money, and taken stress out of your life,
or you just love it, please reach out to return the favor today:

# [acme.js](https://git.coolaj86.com/coolaj86/acme.js)
Free SSL for everybody. The bare essentials of the Let's Encrypt v2 (ACME) API.
Built for [Greenlock](https://git.coolaj86.com/coolaj86/greenlock-express.js),
[by request](https://git.coolaj86.com/coolaj86/greenlock.js/issues/5#issuecomment-8).

# Looking for Quick 'n' Easy&trade;?
This is intented for building ACME API clients in node.js. It is **not** a high-level, fully-integrated solution.

# Demonstration
As this is intended to _build_ ACME clients, there is not a simple 2-line example.
I'd recommend first trying out one of the [greenlock-express.js](https://git.coolaj86.com/coolaj86/greenlock-express.js)
or [Greenlock for Web Servers](https://git.coolaj86.com/coolaj86/greenlock-cli.js) examples,
which are guaranteed to work and have great error checking to help you debug.
Then I'd recommend running the example CLI client with a test domain and then investigating the files used for that example:
```bash
git clone https://git.coolaj86.com/coolaj86/acme.js.git
pushd acme.js/
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 directoryUrl should we use? [https://acme-staging-v02.api.letsencrypt.org/directory]
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`
then you can test it with `examples/https-server.js`.
```
examples/cli.js
examples/genkeypair.js
examples/https-server.js
examples/http-server.js
```
# Let's Encrypt v2 / ACME draft 11 Support

otherwise known as Let's Encrypt v2 (or v02).
- ACME draft 11
- Let's Encrypt v2
- Let's Encrypt v02
```

```
# Install

npm install --save acme
```
Install via git

# API
This API is an evolution of le-acme-core,
but tries to provide a better mapping to the new draft 11 APIs.
Status: Almost stable, but **not semver locked**.
Patch versions will not introduce breaking changes,
but may introduce lower-level APIs.
Minor versions may change return values to include more information.
### Overview
```
var ACME = require('acme').ACME;
ACME.create(opts)
acme.init(acmeDirectoryUrl)
acme.accounts.create(opts)
acme.certificates.create(opts)
```
### Detailed Explanation
```
var ACME = require('acme').ACME;
// Create Instance (Dependency Injection)
var acme = 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
}
```
Helpers & Stuff
```javascript
// Constants
ACME.challengePrefixes['http-01']; // '/.well-known/acme-challenge'
ACME.challengePrefixes['dns-01']; // '_acme-challenge'
```
