# New Documentation & [v4 Migration Guide](https://git.rootprojects.org/root/greenlock.js/src/branch/master/MIGRATION_GUIDE.md)
 | 
						|
 | 
						|
We're still working on the full documentation for this new version,
 | 
						|
so please be patient.
 | 
						|
 | 
						|
To start, check out the
 | 
						|
[Migration Guide](https://git.rootprojects.org/root/greenlock.js/src/branch/master/MIGRATION_GUIDE.md).

# [Greenlock](https://git.rootprojects.org/root/greenlock.js) is Let's Encrypt for JavaScript
 | 
						|
 | 
						|
| Built by [Root](https://rootprojects.org) for [Hub](https://rootprojects.org/hub/)
 | 
						|
 | 
						|
Greenlock™ is an Automated Certificate Management Environement 🔐.
 | 
						|
 | 
						|
| **Greenlock** | [Greenlock Express](https://git.rootprojects.org/root/greenlock-express.js) | [ACME.js](https://git.rootprojects.org/root/acme.js) |
 | 
						|
 | 
						|
It uses **Let's Encrypt** to generate Free SSL Certificates, including **Wildcard** SSL.
 | 
						|
It supports **Automated Renewal** of certs for Fully Automated HTTPS.
 | 
						|
 | 
						|
It's written in plain JavaScript and works in Node, Browsers, and WebPack.
 | 
						|
 | 
						|
the easiest way to integrate Let's Encrypt into your projects, products, and infrastructure.
 | 
						|
 | 
						|
-   [x] **Wildcard** Certificates
 | 
						|
-   [x] **IoT** Environments
 | 
						|
-   [x] **Enterprise** and **On-Prem**
 |

 | 
						|
-   [x] **Web Hosting** Providers
 | 
						|
-   [x] **Commercial** support
 | 
						|
 | 
						|
We've built it simple enough for Hobbyists, and robust enough for the Enterprise.

# Quick Start
 | 
						|
 | 
						|
Greenlock is fully-automated, **SSL Certificate Manager** for IoT, Web Hosting, and Enterprise On-Prem, Edge, and Hybrid Cloud.
 | 
						|
 | 
						|
(though we started building it for [Home Servers](https://rootprojects.org/hub/))
 | 
						|
 | 
						|
You can use it for one-off certificates, like `certbot`,
 | 
						|
but it is _much_ more powerful than that.
 | 
						|
 | 
						|
By setting just a few callbacks to let it know where it should store private keys and certificates,
 | 
						|
it will automatically renew any certificate that you add to it, as long as the process is running.
 | 
						|
 | 
						|
Certificates are renewed every 45 days by default, and renewal checks will happen several times a day.
 | 
						|
 | 
						|
<details>

						|
<summary>1. Configure</summary>
 | 
						|
 | 
						|
```js
 | 
						|
'use strict';
 | 
						|
 | 
						|
var pkg = require('./package.json');
 | 
						|
var Greenlock = require('greenlock');
 | 
						|
var greenlock = Greenlock.create({
 | 
						|
    configDir: './greenlock.d/config.json',
 | 
						|
    packageAgent: pkg.name + '/' + pkg.version,
 | 
						|
    maintainerEmail: pkg.author,
 | 
						|
    staging: true,
 | 
						|
    notify: function(event, details) {
 | 
						|
        if ('error' === event) {
 | 
						|
            // `details` is an error object in this case
 | 
						|
            console.error(details);
 | 
						|
        }
 | 
						|
    }
 | 
						|
});
 | 
						|
 | 
						|
greenlock.manager
 | 
						|
    .defaults({
 | 
						|
        agreeToTerms: true,
 | 
						|
        subscriberEmail: 'webhosting@example.com'
 | 
						|
    })
 | 
						|
    .then(function(fullConfig) {
 | 
						|
        // ...
 | 
						|
    });
 | 
						|
```
 |

 | 
						|
</details>
 | 
						|
 | 
						|
<details>
 | 
						|
<summary>2. Add Domains</summary>
 | 
						|
 | 
						|
The `subject` (primary domain on certificate) will be the id,
 | 
						|
so it's very important that the order of the given domains
 | 
						|
be deterministic.
 | 
						|
 | 
						|
```js
 | 
						|
var altnames = ['example.com', 'www.example.com'];
 | 
						|
 | 
						|
greenlock
 | 
						|
    .add({
 | 
						|
        subject: altnames[0],
 | 
						|
        altnames: altnames
 | 
						|
    })
 | 
						|
    .then(function() {
 | 
						|
        // saved config to db (or file system)
 | 
						|
    });
 | 
						|
```
 | 
						|
 | 
						|
Issuance and renewal will start immediately, and run continually.
 | 
						|
 | 
						|
</details>
 | 
						|
 | 
						|
<details>
 | 
						|
<summary>3. Test for Success</summary>
 | 
						|
 | 
						|
The `store` callbacks will be called every any of your certificates
 | 
						|
are renewed.
 | 
						|
 | 
						|
However, you can do a quick one-off check with `get`.
 | 
						|
 | 
						|
It will return a certificate immediately (if available),
 | 
						|
or wait for the renewal to complete (or for it to fail again).
 | 
						|
 | 
						|
```js
 | 
						|
greenlock
 | 
						|
    .get({ servername: subject })
 | 
						|
    .then(function(pems) {
 | 
						|
        if (pems && pems.privkey && pems.cert && pems.chain) {
 | 
						|
            console.info('Success');
 | 
						|
        }
 | 
						|
        //console.log(pems);
 | 
						|
    })
 | 
						|
    .catch(function(e) {
 | 
						|
        console.error('Big bad error:', e.code);
 | 
						|
        console.error(e);
 | 
						|
    });

## Greenlock#add()
 | 
						|
 | 
						|
Greenlock is a **Automated Certificate Management Environment**.
 | 
						|
 | 
						|
Once you add a "site", it will begin to automatically renew, immediately.
 | 
						|
 | 
						|
The certificates will provided to the `store` callbacks as soon as they are ready, and whenever they renew.
 | 
						|
Failure to renew will be reported to the `notify` callback.
 | 
						|
 | 
						|
You can also retrieve them one-off with `get`.
 | 
						|
 | 
						|
```js
 | 
						|
gl.add({
 | 
						|
    subject: 'example.com',
 | 
						|
    altnames: ['example.com', 'www.example.com', 'exampleapi.com']
 | 
						|
});
 |

| subject         | the first domain on, and identifier of the certificate                                       |
 | 
						|
| altnames        | first domain, plus additional domains<br>note: the order should always be the same           |
 | 
						|
| subscriberEmail | if different from the default (i.e. multi-tenant, whitelabel)                                |
 | 
						|
| challenges      | (same as main config) use if this site needs to use non-default http-01 or dns-01 validation |

## Greenlock#get()
 | 
						|
 | 
						|
**Disclaimer**: This is only intended for testing, demos, and SNICallback
 | 
						|
(in [Greenlock Express](https://git.rootprojects.org/root/greenlock-express.js)).
 | 
						|
 | 
						|
Greenlock is intended to be left running to allow it to fetech and renew certifictates automatically.
 | 
						|
 | 
						|
It is intended that you use the `store` callbacks to new certificates instantly as soon as they renew.
 | 
						|
This also protects you from accidentally stampeding the Let's Encrypt API with hundreds (or thousands)
 | 
						|
of certificate requests.

<summary>Greenlock#renew({ renewBefore })</summary>
 | 
						|
 | 
						|
## Greenlock#renew()
 | 
						|
 | 
						|
This will renew only domains that have reached their `renewAt` or are within the befault `renewOffset`.
 | 
						|
 | 
						|
**Note**: This runs at regular intervals, multiple times a day, in the background.
 | 
						|
You are not required to call it. If you implement the `store` callbacks, the certificates
 | 
						|
will automatically be saved (and if you don't implement them, they all get saved to disk).
 | 
						|
 | 
						|
```js

## Greenlock#manager.remove()
 | 
						|
 | 
						|
To stop certificates from being renewed, you must remove them.
 | 
						|
 | 
						|
If you are implementing your own `manager` callbacks, I recommend that you mark them as deleted
 | 
						|
(i.e. `deleted_at` in your database) rather than actually removing them. Just in case.
 | 
						|
 | 
						|
```js
 | 
						|
gl.remove({
 | 
						|
    subject: 'example.com'
 | 
						|
}).then(function(siteConfig) {
 | 
						|
    // save the old site config elsewhere, just in case you need it again
 | 
						|
});
 | 
						|
```
 | 
						|
 | 
						|
| Parameter | Description                                            |
 | 
						|
| --------- | ------------------------------------------------------ |
 | 
						|
| subject   | the first domain on, and identifier of the certificate |

# Install
 | 
						|
 | 
						|
Greenlock comes with reasonable defaults but when you install it,
 | 
						|
you should also install any plugins that you need.
 | 
						|
 | 
						|
```bash
 | 
						|
npm install --save @root/greenlock@v4
 | 
						|
npm install --save @greenlock/manager

This is what keeps the mapping of domains <-> certificates.

In many cases it will interact with the same database as the Key & Cert Store, and probably the code as well.

## Key and Certificate Store

 | 
						|
 | 
						|
This set of callbacks update your service with new certificates and keypairs.
 | 
						|
 | 
						|
### Account Keys (JWK)
 | 
						|
 | 
						|
(though typically you only have one account key - because you only have one subscriber email)
 | 
						|
 | 
						|
-   accounts.setKeypair({ email, keypair })
 | 
						|
-   accounts.checkKeypair({ email })
 | 
						|
 | 
						|
### Certificate Keys (JWK + PEM)
 | 
						|
 | 
						|
(typically you have one for each set of domains, and each load balancer)
 | 
						|
 | 
						|
-   certificates.setKeypair({ subject, keypair })
 | 
						|
-   certificates.checkKeypair({ subject })
 | 
						|
    (these are fine to implement the same as above, swapping subject/email)
 | 
						|
 | 
						|
### Certificate PEMs
 | 
						|
 | 
						|
-   certificates.set({ subject, pems })
 | 
						|
-   certificates.check({ subject })

## Notes on HTTP-01 & DNS-01 Integrations
 | 
						|
 | 
						|
For Public Web Servers running on a VPS, the **default HTTP-01 challenge plugin**
 | 
						|
will work just fine, for most people.
 | 
						|
 | 
						|
However, for environments that cannot be verified via public HTTP, such as
 | 
						|
 | 
						|
-   **Wildcard Certificates**
 | 
						|
-   **IoT Environments**
 | 
						|
-   **Enterprise On-Prem**
 | 
						|
-   **Private Networks**
 | 
						|
 | 
						|
Greenlock provides an easy way to integrate Let's Encrypt with your existing services
 | 
						|
through a variety of **DNS-01** challenges.
 | 
						|
 | 
						|
### Why not use dns01 for everything?
 | 
						|
 | 
						|
Typically file propagation is faster and more reliably than DNS propagation.
 | 
						|
Therefore, http-01 will be preferred to dns-01 except when wildcards or **private domains** are in use.
 | 
						|
 | 
						|
http-01 will only be supplied as a defaut if no other challenge is provided.

						|
