is it possible making openssl skipping the country/common name prompts?

Question

Is there a way to make openssl skiping the prompts such as

Country Name (2 letter code) [US]:
Organization Name (eg, company) [My Company Name LTD.]:
Common Nam         


        

Answer 1

The -batch optional parameter causes the openssl req command to not prompt for any of the information fields. I use it this way without a config file for automation of self-signed certs.

It is listed in the help:

openssl help req

-batch              Do not ask anything during request generation
