# acme-dns-01-route53
Amazon AWS Route53 DNS + Let's Encrypt for Node.js - ACME dns-01 challenges w/ ACME.js and Greenlock.js
Amazon AWS Route53 DNS + Let's Encrypt for Node.js - ACME dns-01 challenges w/ ACME.js and Greenlock.js
# Features
- Compatible
- Let’s Encrypt v2.1 / ACME draft 18 (2019)
- DNSimple v2 API
- ACME.js, Greenlock.js, and others
- Quality
- node v6 compatible VanillaJS
# Install
```js
npm install --save acme-dns-01-route53
```
AWS API keys:
- Login to your account at: https://console.aws.amazon.com
- Go to Services > IAM > Users, create a new user and assign AmazonRoute53FullAccess policy.
- Click *Securty credentials* tab and then click *Create access key*.
# Usage
First you create an instance with your credentials:
```js
var dns01 = require('acme-dns-01-route53').create({
key: 'your_key',
secret: 'your_secret'
});
```
Then you can use it with any compatible ACME library, such as Greenlock.js or ACME.js.
## Greenlock.js
```js
var Greenlock = require('greenlock-express');
var greenlock = Greenlock.create({
challenges: {
'dns-01': dns01
// ...
}
});
```
See [Greenlock Express](https://git.rootprojects.org/root/greenlock-express.js) and/or [Greenlock.js](https://git.rootprojects.org/root/greenlock.js) documentation for more details.
## ACME.js
```js
// TODO
```
See the [ACME.js](https://git.rootprojects.org/root/acme-v2.js) for more details.
## Build your own
There are only 5 methods:
- `init(config)`
- `zones(opts)`
- `set(opts)`
- `get(opts)`
- `remove(opts)`
```js
dns01
.set({
identifier: { value: 'foo.example.co.uk' },
wildcard: false,
dnsZone: 'example.co.uk',
dnsPrefix: '_acme-challenge.foo',
dnsAuthorization: 'xxx_secret_xxx'
})
.then(function() {
console.log('TXT record set');
})
.catch(function() {
console.log('Failed to set TXT record');
});
```
See acme-dns-01-test for more implementation details.
# Tests
```bash
# node ./test.js domain-zone key secret
node ./test.js example.com xxxxx yyyyy
```
