le-challenge-dns

A dns-based strategy for node-letsencrypt for setting, and clearing ACME DNS-01 challenges issued by the ACME server.

DRAFT

This details how any dns-based challenge will work with node-letsencrypt, but is not yet implemented specifically (though it is in the pipeline at present, obviously).

Usage

var leChallenge = require('le-challenge-dns').create({
  ttl: 600
, debug: false
});

var LE = require('letsencrypt');

LE.create({
  server: LE.stagingServerUrl                               // Change to LE.productionServerUrl in production
, challenge: leChallenge
});

NOTE: If you request a certificate with 6 domains listed, it will require 6 individual challenges.

Exposed Methods

For ACME Challenge:

• set(opts, domain, key, val, done)
• get(defaults, domain, key, done)
• remove(defaults, domain, key, done)

For node-letsencrypt internals:

• getOptions() returns the internal defaults merged with the user-supplied options
• loopback(defaults, domain, key, value, done) should test, by external means, that the ACME server's challenge server will succeed
