Hi Arthur,
You can create an certificate on the AWS website after you've create a free account.
I hope this will help you continue to follow the tutorial :-)
Cheers
Hi Jeffrey, first of all thanks a lot for your response. I have indeed managed to create a certificate and private key on AWS, However the tutorial seems to also refer to a so called "CA" or "rootCA" (see below image 1) .
On AWS, you sort of get the option to create a Root CA (see image 2), but all this does is open a new web page (see image3)
On the tutorial, they seem to have a RooCA.pem.crt file in the resources. I was wondering how that was created.
Thanks again!
