Right now this uses [`letsencrypt-python`](https://github.com/Daplie/node-letsencrypt-python),
but it's built to be able to use a node-only javascript version (in progress).
```bash
# install the python client (takes 2 minutes normally, 20 on a raspberry pi)
git clone https://github.com/letsencrypt/letsencrypt
pushd letsencrypt
./letsencrypt-auto
```
**moving towards a python-free version**
There are a few partially written javascript implementation, but they use `forge` instead of using node's native `crypto` and `ursa` - so their performance is outright horrific (especially on Raspberry Pi et al). For the moment it's faster to use the wrapped python version.
Once the `forge` crud is gutted away it should slide right in without a problem. Ping [@coolaj86](https://coolaj86.com) if you'd like to help.
Usage
=====
Here's a simple snippet:
See [letsencrypt-cli](https://github.com/Daplie/node-letsencrypt-cli)
and [letsencrypt-express](https://github.com/Daplie/letsencrypt-express)
```javascript
var config = require('./examples/config-minimal');
config.le.webrootPath = __dirname + '/tests/acme-challenge';
var le = require('letsencrypt').create(config.backend, config.le);
var le = require('letsencrypt').create(config.le);
le.register({
agreeTos: true
, domains: ['example.com'] // CHANGE TO YOUR DOMAIN
, email: 'user@email.com' // CHANGE TO YOUR EMAIL
, standalone: true
}, function (err) {
if (err) {
console.error('[Error]: node-letsencrypt/examples/standalone');

#### How to write a backend
A backend must implement (or be wrapped to implement) this API:
* `fetch(hostname, cb)` will cb(err, certs) with certs from disk (or null or error)
* `register(args, challengeCb, done)` will register and or renew a cert
* args = `{ domains, email, agreeTos }` MUST check that agreeTos === true
* challengeCb = `function (challenge, cb) { }` handle challenge as needed, call cb()
This is what `args` looks like:

(it's expected that the client will follow the same conventions as
the python client, but it's not necessary)
```javascript
return {
fetch: function (args, cb) {
// NOTE: should return an error if args.domains cannot be satisfied with a single cert
// (usually example.com and www.example.com will be handled on the same cert, for example)
if (errorHappens) {
// return an error if there is an actual error (db, etc)
cb(err);
return;
}
// return null if there is no error, nor a certificate
else if (!cert) {
cb(null, null);
return;
}
// NOTE: if the certificate is available but expired it should be
// returned and the calling application will decide to renew when
// it is convenient
// NOTE: the application should handle caching, not the library
// return the cert with metadata
cb(null, {
cert: "/*contcatonated certs in pem format: cert + intermediate*/"
