Creating a Certificate Authority with OpenSSL

This tutorial will guide you step-by-step to creating a certificate authority using OpenSSL, with a three-tier structure (root, intermediate, application). All key materials are created with ECC.

Staging

The first step is to create the directory in which the CA will reside. As a simple example, we will work out of /root/ca. We will create a directory, /root/ca/db, to store the CA database flat files. Within this directory, three files must be created as follows:

touch /root/ca/db/index.txt
touch /root/ca/db/index.txt.attr 
echo 100000 > /root/ca/db/serial

- Command Prompt

notepad %UserProfile%\.wslconfig
