Im using certbot with dns challenge (cloudflare api token) to renew letsencrypt cert for my nginx proxy. I want also to create CA cert to sign longterm certs for upstream servers/services and set nginx to trust CA cert. Longterm because of no possibility to automate renewal for those devices/services. Will stepCA have any use for me or just use openssl?
Oh no step-ca what are you doing?
Sorry i had to do this
Joking aside I recommend setting up internal CA with easyrsa project from OpenVPN github repository
