le-challenge-dns

| Sponsored by ppl | greenlock.js (library) | greenlock-express.js | greenlock-cli.js | acme-v2.js |

A manual (interactive CLI) dns-based strategy for node-letsencrypt for setting, retrieving, and clearing ACME DNS-01 challenges issued by the ACME server

Prints out a subdomain record for _acme-challenge with keyAuthDigest to be tested by the ACME server.

You can then update your DNS manually by whichever method you use and then press [enter] to continue the process.

_acme-challenge.example.com   TXT   xxxxxxxxxxxxxxxx    TTL 60

Install

npm install --save le-challenge-dns@2.x

Usage

var leChallengeDns = require('le-challenge-dns').create({
  debug: false
});

var LE = require('letsencrypt');

LE.create({
  server: LE.stagingServerUrl                               // Change to LE.productionServerUrl in production
, challengeType: 'dns-01'
, challenges: {
    'dns-01': leChallengeDns
  }
, approveDomains: [ 'example.com' ]
});

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

Exposed Methods

For ACME Challenge:

• set(opts, domain, challange, keyAuthorization, done)
• get(defaults, domain, challenge, done)
• remove(defaults, domain, challenge, done)

Note: get() is a no-op for dns-01.

For node-letsencrypt internals:

• getOptions() returns the internal defaults merged with the user-supplied options
• loopback(defaults, domain, challange, done) performs a dns lookup of the txt record
• test(opts, domain, challange, keyAuthorization, done) runs set, loopback, remove, loopback
