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?
So far youre the only one who fully read/understood my question. The rest mostly just recommend what they use. Which is also fine, yet these not answer the issue. Thank you!
