Step 1 - Create CA certificate and key

Define a certificate authority (CA) to use for signing and issuing certificates, by creating its certificate and key. You can use the openssl utility on Linux to create the key and certificate. In the following example, openssl is used to create CA certificate and key:

openssl genrsa -out ca.key 2048
openssl req -x509 -new -nodes -key ca.key -subj "/CN=ITX_RS_ROOT_CA" -days 3650 -out ca.crt
