Creating an OpenSSL configuration file

The OpenSSL configuration file contains X.509 extensions for generating and signing certificate requests.

Run the following command:

nano /etc/certs/openxpki_democa/openssl.conf

Note: If your server is reachable using the fully qualified domain name (FQDN), then use the DNS of the server instead of its IP address.

# x509_extensions               = v3_web_extensions
# x509_extensions               = v3_ca_reqexts # not for root self-signed, only for issuing
## x509_extensions              = v3_datavault_reqexts # not required self-signed
# x509_extensions               = v3_scep_reqexts
