Exposed Methods
Exposed (Promise) Methods
---------------
For ACME Challenge:
* `set(opts, domain, key, val, done)`
* `get(defaults, domain, key, done)`
* `remove(defaults, domain, key, done)`
* `set(opts)`
* `remove(opts)`
For node-letsencrypt internals:
The options will look like this for normal domains:
* `getOptions()` returns the internal defaults merged with the user-supplied options
```js
{ challenge: {
type: 'http-01'
, identifier: { type: 'dns', value: 'example.com' }
, wildcard: false
, expires: '2012-01-01T12:00:00.000Z'
, token: 'abc123'
, thumbprint: '<<account key thumbprint>>'
, keyAuthorization: 'abc123.xxxx'
, dnsHost: '_acme-challenge.example.com'
, dnsAuthorization: 'yyyy'
, altname: 'example.com'
}
}
```
And they'll look like this for wildcard domains:
```js
{ challenge: {
type: 'http-01'
, identifier: { type: 'dns', value: 'example.com' }
, wildcard: true
, expires: '2012-01-01T12:00:00.000Z'
, token: 'abc123'
, thumbprint: '<<account key thumbprint>>'
, keyAuthorization: 'abc123.xxxx'
, dnsHost: '_acme-challenge.example.com'
, dnsAuthorization: 'yyyy'
, altname: '*.example.com'
}
}
```
The only difference is that `altname` will have the `*.` prefix (which you would expect
but, of course, can't work as a specific a DNS record) and the `wildcard` property is `true`.
Optional
* `get(limitedOpts)`
Because the get method is apart from the main flow (such as a DNS query),
it's not always implemented and the options are much more limited in scope:
```js
{ challenge: {
type: 'http-01'
, identifier: { type: 'dns', value: 'example.com' }
, wildcard: false
, token: 'abc123'
, altname: 'example.com'
}
}
```
If there were an implementation of Greenlock integrated directly into
a NameServer (which currently there is not), it would probably look like this:
```js
{ challenge: {
type: 'dns-01'
, identifier: { type: 'dns', value: 'example.com' }
, token: 'abc123'
, dnsHost: '_acme-challenge.example.com'
}
}
```
