it asked for some attributes:

-----
Country Name (2 letter code) [XX]:IT
State or Province Name (full name) []:Rome
Locality Name (eg, city) [Default City]:Rome
Organization Name (eg, company) [Default Company Ltd]:PP

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:claudio
An optional company name []:cc

is it possible to add an additional custom attribute during the creation?

Thank you in advance Claudio

Answer 1

1) login as root
2) open file openssl.cnf
3) add your custom attribute in "[new oids]" section
4) add description in "req_distinguished_name" section
5) save & close
6) create your new certificate

[ new oids]
 newCustom=1.2.3.4.5.6

[req_distinguished_name] 
 newCustom             = new custom attibute

openssl req -new -key server.key -out server.csr
nter pass phrase for server.key:
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.
