acme-http-01-cli | a Root project

An extremely simple reference implementation of an ACME (Let's Encrypt) http-01 challenge strategy.

This generic implementation can be adapted to work with any node.js ACME client, although it was built for Greenlock and ACME.js.

GET http://example.com/.well-known/acme-challenge/xxxxxxxxxxxxxxxx

• Prints the ACME challenge URL and Key Authorization to the terminal
  • (waits for you to hit enter before continuing)
• Asks you to enter (or upload) the Key Authorization challenge response.
• Let's you know when the challenge as succeeded or failed, and is safe to remove.

Other ACME Challenge Reference Implementations:

• acme-http-01-fs
• acme-http-01-cli
• acme-dns-01-cli

Install

npm install --save acme-http-01-cli@3.x

Usage

var Greenlock = require('greenlock');

Greenlock.create({
  ...
, challenges: { 'http-01': require('acme-http-01-cli').create({ debug: true })
              , 'dns-01': require('acme-dns-01-cli')
              , 'tls-alpn-01': require('acme-tls-alpn-01-cli')
              }
  ...
});

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

Exposed (Promise) Methods

For ACME Challenge:

• set(opts)
• remove(opts)

The http-01 strategy does not support wildcard domains (whereas dns-01 does). The options will look like this (which you can see when debug: true is set):

{ 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'
  }
}

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:

{ challenge: {
    type: 'http-01'
  , identifier: { type: 'dns', value: 'example.com' }
  , wildcard: false
  , token: 'abc123'
  , altname: 'example.com'
  }
}
