AWS S3 does not support HTTPS. One of the options to secure the domain is to create a public SSL certificate and use Cloudfront to deliver the content.

• Go to AWS Certificate Manager

• Click Get Started under Provision Certificate

• Choose Request a public certificate and click the Request a certificate button

• Fill in the domain and subdomain names that need to be added to this certificate. Adding a * at the beginning will cover all the subdomains.

• Choose DNS validations and click Next.

If the domain name was registered with Amazon, DNS validation is easier.

• Add any tag name that you want and click Review

• Review the information and click Confirm and request

A request will be in progress.

• Click on the arrow in front of the domain name
• Click on the Create Record in Route 53 button.

• In the resulting modal, click Create

• A success message will show up if everything worked well.
• Do the same for the subdomains, if you have one.

• The Certificate Manager should have the status as Issued and the validation status for the domain should be Succes
• In use? says No because the certificate is not used by a service like CloudFront. Since S3 uses HTTP, this certificate cannot be used on an S3 bucket.
