I am a little confused about setting up HTTPS for single-instance Elastic Beanstalk. I understand I must configure the nginx\conf.d\https.conf file to point to the certificate and key files. However, Squarespace issued my certificate and key for my domain. I could easily download the certificate from the browser but couldn’t get the key from them. So should I create a certificate through Amazon using my key or is there anything that I am missing?
