Step CA for homelab certificate management
Getting the root certificate
You can retrieve the root certificate by going to the /roots.pem route on
your CA. e.g. open curl -k https://ca.example/roots.pem in order to get the
root certificate. This is just one part of what step ca bootstrap does.
You should probably know the fingerprint of the certificate. Verify the
fingerprint with openssl x509 -in roots.pem -noout -text.
Other API endpoints
There are a number of additional API endpoints, which you can find in the
Route() function in the api subfolder.
A couple of ones I like to note: /version and /health. And, of course,
the /roots (in JSON) and /roots.pem (in PKCS#9) endpoints.
