Hello all. I would create a .p12 file for signing PDFs with a PADES signature. So I don’t have a site, I just need the certificate and the key. How can I do to get them? Certbot wants absolutely a domain.
I ran this command:
sudo certbot certonly --standalone
It produced this output:
Failed authorization procedure. marcosulla.org (http-01): urn:ietf:params:acme:error:connection :: The server could not connect to the client to verify the domain :: dns :: DNS problem: NXDOMAIN looking up A for marcosulla.org
The operating system my web server runs on is (include version):
Lubuntu 18.0.4 (it’s my laptop)
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot):
Yes, Let’s Encrypt certificates are only valid for authenticating online sites and services with TLS and can’t be used for file or code signing. For these purposes, you’ll need to look for a certificate from a different CA.
