Simple Commerce Set-up

Hello,

Does anyone have a concise and understandable way of setting up the Simple Commerce Module to interact with your Paypal account?

I am having difficulty with this:

The private key is the portion of the encryption method that is kept secret and not sent to anyone. To create your private key, key in the following at the command line:

openssl genrsa -out private_key.pem 1024

As well as this:

The public certificate is the portion of the encryption method that you provide PayPal to enable them to accept encrypted payments for you. To create your public certificate, key in the following at the command line:

openssl req -new -key private_key.pem -x509 -days 730 -out public_certificate.pem

What is the “command line” and how exactly do I do this?

Thanks for your help.
