Built +and supported by [the EFF](https://www.eff.org/), it’s the standard-bearer for +production-grade command-line ACME. + +To get a certificate from `step-ca` using `certbot` you need to: + +1. Point `certbot` at your ACME directory URL using the `--`server flag. +2. Tell `certbot` to trust your root certificate using the `REQUESTS_CA_BUNDLE` environment variable. + +For example: + +``` +$ sudo REQUESTS_CA_BUNDLE=$(step path)/certs/root_ca.crt \ + certbot certonly -n --standalone -d foo.internal \ + --server https://ca.internal/acme/acme/directory +``` + +`sudo` is required in `certbot`'s [*standalone* +mode](https://certbot.eff.org/docs/using.html#standalone) so it can listen on +port 80 to complete the `http-01` challenge. If you already have a webserver +running you can use [*webroot* +mode](https://certbot.eff.org/docs/using.html#webroot) instead. With the +[appropriate plugin](https://certbot.eff.org/docs/using.html#dns-plugins) +`certbot` also supports the `dns-01` challenge for most popular DNS providers. +Deeper integrations with [nginx](https://certbot.eff.org/docs/using.html#nginx) +and [apache](https://certbot.eff.org/docs/using.html#apache) can even configure +your server to use HTTPS automatically (we'll set this up ourselves later). All +of this works with `step-ca`. + +You can renew all of the certificates you've installed using `cerbot` by running: + +``` +$ sudo REQUESTS_CA_BUNDLE=$(step path)/certs/root_ca.crt certbot renew +``` + +You can automate renewal with a simple `cron` entry: + +``` +*/15 * * * * root REQUESTS_CA_BUNDLE=$(step path)/certs/root_ca.crt certbot -q renew +``` + +The `certbot` packages for some Linux distributions will create a `cron` entry +or [systemd +timer](https://stevenwestmoreland.com/2017/11/renewing-certbot-certificates-using-a-systemd-timer.html) +like this for you. This entry won't work with `step-ca` because it [doesn't set +the `REQUESTS_CA_BUNDLE` environment +variable](https://github.com/certbot/certbot/issues/7170). You'll need to +manually tweak it to do so. + +More subtly, `certbot`'s default renewal job is tuned for Let's Encrypt's 90 +day certificate lifetimes: it's run every 12 hours, with actual renewals +occurring for certificates within 30 days of expiry. By default, `step-ca` +issues certificates with *much shorter* 24 hour lifetimes. The `cron` entry +above accounts for this by running `certbot renew` every 15 minutes. You'll +also want to configure your domain to only renew certificates when they're +within a few hours of expiry by adding a line like: + +``` +renew_before_expiry = 8 hours +``` + +to the top of your renewal configuration (e.g., in `/etc/letsencrypt/renewal/foo.internal.conf`). + +## Feedback + +`step-ca` should work with any ACMEv2 +([RFC8555](https://tools.ietf.org/html/rfc8555)) compliant client that supports +the http-01 or dns-01 challenge.
