// Finally, you need an implementation of `challengeStore`:

// Note:
// key is the xxxx part of `/.well-known/acme-challenge/xxxx`
// value is what is needs to be return the the requesting server
//
// it is very common to store this is a directory as a file
// (and you can totally do that if you want to, no big deal)
// but that's super inefficient considering that you need it
// for all of 500ms and there's no sense in that.
