le-challenge-sni

A strategy for node-letsencrypt for setting, retrieving, and clearing ACME challenges by registering self-signed certs with the SNI handler.

It is designed to handle tls-sni-01 and tls-sni-02 challenges.

Install

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

Usage

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

var LE = require('letsencrypt');

LE.create({
  server: LE.stagingServerUrl
, challengeType: "tls-sni-01"
, challenge: leChallenge
});

le-challenge-sni requires the sni option to letsencrypt to have cacheCerts and uncacheCerts methods. These are used to register/unregister the certificates. The default le-sni-auto instance satisfies this requirement.

It also requires the challengeType option to letsencrypt to be either tls-sni-01 or tls-sni-02 and will generate and register certificates accordingly.

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 user supplied options, if any (no effect)
