I am currently experiencing an issue with AWS S3 Buckets. I've successfully managed to set the roles and permission for specific objects and make some of them downloadable for everyone via a specific link.
https://<sub-domain>.s3.eu-central-1.amazonaws.com/path/path/a87cd6a9-a2d9-4231-beb3-6b1e76d90490/8e958264-4baf-4fbe-918b-c30d9d450671.jpg
This link is a download link for an image and when I click it the browser recommends me to "Stay Safe" and the connection to this Server is not privat / secure.
Any ideas how I can verify the SSL Certificate?
You can't use https for downloading objects from S3. Its only available through http, thus there are no certificates to validate. For ssl you need to use CloudFront with S3:

We are running a static website in S3 using CloudFront for distribution. CloudFront has an SSL Certificate assigned, so we are receiving HTTPS traffic and redirecting HTTP to HTTPS.
What I'm trying to determine is that does mean that TLS is enforced from CloudFront to the S3 Static Site?
If so, I am looking for a reference stating that - we need to have end to end encryption applied for compliance and I need to be able to verify/prove that this is in place.
Thanks !!!
does mean that TLS is enforced from CloudFront to the S3 Static Site?
No its not. Static S3 websites are HTTP only. Docs explain that:
If your Amazon S3 bucket is configured as a website endpoint, you can't configure CloudFront to use HTTPS to communicate with your origin because Amazon S3 doesn't support HTTPS connections in that configuration.
we need to have end to end encryption applied for compliance
For end-to-end ssl you have to setup setup origin access identity (OAI) for your CF. This means that the bucket can't be in website mode. Instead, it has to be configured for OAI access as explained in the docs. To enforce HTTPS between CF and S3 you must ensure that your "Viewer Protocol Policy to Redirect HTTP to HTTPS or HTTPS Only".
Can someone explain why, when Amazon S3 uses a wildcard SSL certificate, you can not access the static website through https?
For accessing static website over https you would need to user cloudfront on top of your bucket.
for installing a SSL certificate you would need a server, well S3 is just for storage, you cannot install SSL certificate over S3.

I've got a static S3 website. When I log in, I can see that the endpoint is http://www.example.com.s3-website.eu-west-2.amazonaws.com, but I've seen answers claiming that the site should be accessible via HTTPS at https://www.example.com.s3-website.eu-west-2.amazonaws.com. This doesn't work though.
Did AWS used to support HTTPS for static sites and have now stopped it, or do I need to enable it somehow?
The website hosting section on S3 now has this note at the bottom of the page:
The Amazon S3 website endpoints do not support HTTPS. For information about using HTTPS with an Amazon S3 bucket, see How do I use CloudFront to serve HTTPS requests for my Amazon S3 bucket? and Requiring HTTPS for Communication Between CloudFront and Your Amazon S3 Origin.
Seems the only option now is to use CloudFront. Quite disappointing when you just want a quick and dirty HTTPS website and would happily use https://examplebucket.s3-website-us-west-2.amazonaws.com/ as the URL, which would work fine with a wildcard SSL certificate.
So the answer is no, it's not possible to use HTTPS for S3 static websites directly like I'm trying to do. From the docs:
Note the following about using HTTPS when the origin is an Amazon S3
bucket:
* If your Amazon S3 bucket is configured as a website endpoint, you can't
configure CloudFront to use HTTPS to communicate with your
origin because Amazon S3 doesn't support HTTPS connections in that
configuration.
You cannot use periods in the bucket name. If you do use periods, Amazon's wildcard certificate won't work.
Quoting the BucketRestrictions documentation:
When you use virtual hosted–style buckets with Secure Sockets Layer (SSL), the SSL wildcard certificate only matches buckets that don't contain periods. To work around this, use HTTP or write your own certificate verification logic. We recommend that you do not use periods (".") in bucket names when using virtual hosted–style buckets.
I need to set an Amazon Domain as a custom domain for a Heroku app. I found the next tutorial https://devcenter.heroku.com/articles/route-53 but it doesn't work if the app needs https requests. The first idea was to set up the SSL Certificate in Heroku, but the SSL Amazon Domain manager doesn't allow to download the certificate, so the SSL need to be managed by AWS.
What is the best way to add Amazon SSL to a Heroku app?
The best option I found was to create an AWS CloudFront and configure it like Karan describes in his answer but with some add-ons:
Create a certificate from AWS Certificate Manager and approve it.
Create a CloudFront distribution with the Origin Domain Name as your Heroku URL such as myapp.herokuapp.com and the custom SSL certificate as the one you created from the AWS Cert Manager.
While creating the distribution, make sure that you have the TTL as 0, else all the responses will be cached
If you don't complete this step probably you will get an error like this:
This distribution is not configured to allow the HTTP request method that was used for the request. The distribution supports only cachable requests.
Follow the guide I mention in the question [https://devcenter.heroku.com/articles/route-53][4]
Amazon created SSL certificates only work with supported Amazon services such as Elastic Load Balancers, CloudFront distributions and API Gateway.
The easiest method to use Amazon SSL certificates is to add a load balancer. Another method is to enable CloudFront.

I try access to Amazon AWS S3 with https.
This link with http works: http://sc-st01.s3-website-eu-west-1.amazonaws.com/
But this not: https://sc-st01.s3-website-eu-west-1.amazonaws.com/
Is there any setting to enable it?
I use CNAME also but i think the problem is in access to https.
Thank you for any advice.
UPDATE: This refers to using S3 to host static web content.
If you are using your S3 bucket to host static web content, then HTTPS isn't supported. To quote the AWS doc, it says under the Test your website section:
Note
HTTPS access to the website is not supported.
Not very helpful. If you are interested in learning how S3 virtual hosting works, you can read more about it here.
To serve your static web content over HTTPS, you will need to set up an AWS CloudFront distribution, which is quite straight forward via the AWS Management Console. The only configurations that will require special attentions are:
Origin Domain Name: This should refer to the URI of your S3 bucket. In your case, it will be sc-st01.s3-website-eu-west-1.amazonaws.com
Viewer Protocol Policy: Default to HTTP and HTTPS Only
Alternate Domain Names (CNAMEs): CNAME you set up in your DNS.
SSL Certificate: Either Default CloudFront Certificate or Custom SSL Certificate if you have one. Note that setting up custom SSL certificate is more involved as it needs to be uploaded to the IAM.
Default Root Object: The default file you want to serve when your user visits your static web site.
Once you're done with setting up the configurations, it will usually take 5 to 10 minutes for the new distribution to be fully configured and set up. Refer the Status field on the CloudFront management dashboard for progress. When ready, you will see the new Domain Name of your distribution. You should be able to access the static web content in your S3 bucket (assuming that the permissions of the content is granted to Everyone) by navigating to the http: or https:// URL of your distribution Domain Name.
I will also recommend checking out the CloudFront pricing to ensure if you are aware of what is free, and what isn't.
