Stateless Mode

Configure your webserver to respond statelessly to challenges for a given account key. This requires nothing more than a one-time web server configuration change and no "moving parts".

  1. First get your account key thumbprint:
root@ed:~# acme.sh --register-account
[Mon Feb  6 21:40:18 CST 2017] Registering account
[Mon Feb  6 21:40:19 CST 2017] Already registered
[Mon Feb  6 21:40:21 CST 2017] Update success.
[Mon Feb  6 21:40:21 CST 2017] ACCOUNT_THUMBPRINT='6fXAG9VyG0IahirPEU2ZerUtItW2DHzDzD9wZaEKpqd'

Remember the the thumbprint in the last line: 6fXAG9VyG0IahirPEU2ZerUtItW2DHzDzD9wZaEKpqd

  1. Configure the nginx server to return the account key thumbprint:
http {
...
server {
...
  location ~ ^/\.well-known/acme-challenge/([-_a-zA-Z0-9]+)$ {
    default_type text/plain;
    return 200 "$1.6fXAG9VyG0IahirPEU2ZerUtItW2DHzDzD9wZaEKpqd";
  }
...
}
}
  1. Ok, you can issue cert now.
acme.sh --issue -d example.com  --stateless
