[default]
log_file = certgen.log

[config]
csvfile = serial.csv
yamlfile = csr.yaml

Config add custom path to config ini

Create one certificate

$ cert create [FQDN]

using config.ini:

$ cert create -c [FQDN]

Create multiple certificate

using csv file:

$ cert create-multiple [-a] [--csv=[path/csv]]

‘-a’ is only if you use absolute path of –csv, if you don’t use absolute path, it will search in csv folder

using config.ini:

$ cert -c create-multiple [-a] [--csv=[path/csv]]
