Create your CA Private Key for OpenSSL

I needed to create a private key using OpenSSL.

It didn't take me long to find the necessary commands.

Note: I will assume that you have installed OpenSSL into the C:\OpenSSL folder.

Change into the C:\OpenSSL\share folder.

Type:

..\bin\openssl genrsa -des3 -out cakey.pem 2048

The above command will create your CA's private key. Now you will need to generate a Public certificate for your certificate authority (CA). During this process you will be prompted to enter a few details about your CA.

Type:

openssl req -new -key cakey.pem -x509 -days 1825 -extensions v3_ca -out capub.crt
