You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.

Locality Name (eg, city) [Default City]:fx
Organization Name (eg, company) [Default Company Ltd]:fx
Organizational Unit Name (eg, section) []:fx
