# New Documentation & [v2/v3 Migration Guide](https://git.rootprojects.org/root/greenlock.js/src/branch/v3/MIGRATION_GUIDE_V2_V3.md)
Greenlock v3 was just released from private beta **today** (Nov 1st, 2019).
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/v3/MIGRATION_GUIDE_V2_V3.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 🔐.
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] **Private** Networks
- [x] **Localhost** Development
- [x] **Web Hosting** Providers
- [x] **Commercial** support
We've built it simple enough for Hobbyists, and robust enough for the Enterprise.

# SSL Certificate & Domain Management

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.
- set({ subject, altnames, renewAt })
- find({ altnames, renewBefore })
```js
// should return a list of site configs:
[
{
subject: 'example.com',
altnames: ['example.com', 'exampleapi.com'],
renewAt: 1575197231760
},
{
subject: '*.example.com',
altnames: ['*.example.com'],
renewAt: 1575197231760,
challenges: {
'dns-01': {
module: 'acme-dns-01-dnsimple',
apikey: 'xxxx'
}
}
}
];

- remove({ subject })

# Key and Certificate Store
Full Docs: https://git.rootprojects.org/root/greenlock-store-test.js
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 })

# ACME Challenge HTTP-01 Strategies
Full Docs: https://git.rootprojects.org/root/acme-http-01-test.js
This validation and authorization strategy is done over plain HTTP on Port 80.
These are used to set files containing tokens that Let's Encrypt will fetch from each domain
before authorizing a certificate.
**NOT for Wildcards**.
- init({ request })
- set({ challenge: { type, token, keyAuthorization, challengeUrl } })
- get({ challenge: { type, token } })
- remove({ challenge: { type, token } })

This validation and authorization strategy is done over DNS on UDP and TCP ports 53.

These are used to set TXT records containing tokens that Let's Encrypt will fetch for
each domain before authorizing a certificate.
- init({ request })
- zones()
- set({ challenge: { type, dnsZone, dnsPrefix, dnsHost, keyAuthorizationDigest } })

< summary > Greenlock#add({ subject, altnames })< / summary >
# Greenlock#add()
Greenlock is a **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']
});
```
| Parameter | Description |
| --------------- | -------------------------------------------------------------------------------------------- |
| 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.
- [Store Callback Documentation ](https://git.rootprojects.org/root/greenlock-store-test.js )
```js
return greenlock.get({ servername }).then(function(site) {
if (!site) {
console.log(servername + ' was not found in any site config');
return;
}
var privkey = site.pems.privkey;
var fullchain = site.pems.cert + '\n' + site.pems.chain + '\n';
console.log(privkey);
console.log(fullchain);
});
```
| Parameter | Description |
| ---------- | ------------------------------------------------------------- |
| servername | any altname listed on the certificate (including the subject) |
< / details >
< details >
< summary > Greenlock#renew()< / 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
return greenlock.renew({}).then(function(results) {
results.forEach(function(site) {
if (site.error) {
console.error(site.subject, site.error);
return;
}
console.log('Renewed certificate for', site.subject, site.altnames);
});
});
```

# 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
- **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** infrastructure
Why
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.
You can use ACME (Let's Encrypt) with several ready-made integrations
# Ready-made Integrations
Greenlock Express integrates between Let's Encrypt's ACME Challenges and many popular services.
