An fs-based strategy for Greenlock for setting, retrieving, and clearing ACME (Let's Encrypt) challenges issued by the ACME server
This places the acme challenge in an appropriate directory in the specified
and removes it once the challenge has either completed or failed.
- Safe to use with node cluster
- Safe to use with ephemeral services (Heroku, Joyent, etc)
npm install --save email@example.com
var http01Challenge =;var Greenlock = ;Greenlock;
NOTE: If you request a certificate with 6 domains listed, it will require 6 individual challenges.
For ACME Challenge:
set(opts, domain, key, val, done)
get(defaults, domain, key, done)
remove(defaults, domain, key, done)
