# To create a RSA root cerificate need to following two steps:

1. Create a private key for the CA:

openssl req -nodes -newkey rsa:1024 -keyout <key file> -out <CA req file> -config <config file>
The config file is input parameter, and should be present in advance.

Example: openssl req -nodes -newkey rsa:1024 -keyout cakey.pem -out careq.pem -config rsa.config

2. Create the CA certificate:

openssl x509 -req -in <CA req> -extfile <config file> -extensions v3_ca -signkey <key file> -out <CA cert file>  -days 3650

Example: openssl x509 -req -in careq.pem -extfile rsa.config -extensions v3_ca -signkey cakey.pem -out cacert.pem  -days 3650


1. 

openssl req -nodes -newkey rsa:1024 -keyout cakey.pem -out careq.pem -config rsa.config


2.

openssl x509 -req -in careq.pem -extfile rsa.config -extensions v3_ca -signkey cakey.pem -out symbiantestallcapabilitiesca.pem  -days 3650
