I am hosting a static website on AWS S3 bucket.
I have setup a CloudFront distribution with this bucket as origin.
I have created 2 alternate domains in my distributions
my-domain.com
*.my-domain.com
my-domain is registered in route53
I have created a hosted zone in which I have created records for my-domain.com and *.my-domain.com to point to my CloudFront distribution.
In AWS Certificate manager I have created a certificate for my-domain.com and *.my-domain.com that I have added to the CloudFront distribution.
At this point, everything is working fine and I get the expected result when I browse 'https://my-doamin.com
Now what I want to achieve is that my website is only accessible through https. I want users trying to access with http to be blocked.
I have setup my distribution behaviour to 'https only' and it works fine to block direct http access to my distribution (http://my-distribution.com)
However it is not enough to block http access through the altername domain (http://my-domain.com)
Through AWS documentation https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/cnames-https-dedicated-ip-or-sni.html I have figured out I needed to activate SNI.
The steps in the documentation are :
To switch from a custom SSL/TLS certificate with dedicated IP addresses to SNI.
Sign in to the AWS Management Console and open the CloudFront console at https://console.aws.amazon.com/cloudfront/v3/home.
Choose the ID of the distribution that you want to view or update.
Choose Distribution Settings.
On the General tab, choose Edit.
Change the setting of Custom SSL Client Support to Only Clients that Support Server Name Indication (SNI).
Choose Yes, Edit.
I believe I am following all these steps but in step 5 there is nowhere I can find where I can change the setting of Custom SSL Client Support and I am blocked.
Here is what I see instead:

I bought a domain (xyz.com) from some domain provider.
I pointed its nameserver to Cloudflare to host dns.
I created an S3 bucket with name (xyz.com) and hosted my static website on it.
I added a CNAME record on cloudflare to point to the static website url of bucket.
Everything is working fine till here. (xyz.com) opens the static website hosted on S3 bucket.
Now I want to create (api.xyz.com) for AWS API Gateway custom domain.
I want API Gateway to trigger Lambda so that it computes and return back the result.
For above I added another CNAME record in cloudflare so that AWS ACM is able to issue me a certificate for (api.xyz.com). After few minutes ACM was able to issue me a certificate.
Now I added the custom domain in API Gateway and selected the above ACM certificate.
When I make http GET call to my api chrome shows:
This site can’t be reached
api.xyz.com’s server IP address could not be found.
DNS_PROBE_FINISHED_NXDOMAIN
How to fix this?
I am a beginner and maybe I am using some terms wrong. Please Ignore
Create a CNAME record to your api gateway and make sure you hit it using https
wanted to enable https on my subdomain, with static site hosting.
Some how s3 throws up :
a.example.com uses an invalid certificate. The certificate is only valid for the following names: *.s3.amazonaws.com, s3.amazonaws.com. error Code : SSL_ERROR_BAD_CERT_DOMAIN
S3 doesn't directly support SSL with a custom domain name on a static web site. This feature is provided by CloudFront, which you configure in front of the S3 bucket.
http://docs.aws.amazon.com/AmazonS3/latest/dev/website-hosting-cloudfront-walkthrough.html
After configuring CloudFront, you then need to go to Amazon Certificate Manager, ensure that the selected region is us-east-1¹ and either obtain a new SSL certficate, or import the certificate you purchased from a third party vendor.
http://docs.aws.amazon.com/acm/latest/userguide/gs.html
Then, configure the CloudFront distribution to use the certificate from ACM.
¹ us-east-1. Because of the internal design of CloudFront's integration with ACM, you always select us-east-1 in Amazon Certificate Manager regardless of the region where your S3 bucket is located. This does not have any pricing or performance implications.
Say, for example, I have an Azure web app named MyApp and is hosted on Azure as MyApp.azurewebsites.net. It's my understanding that there is nothing I need to do to secure the URL with SSL, as it's done, by default, with a single certificate. So I can already have my users access the app via https://MyApp.azurewebsites.net, and it will be secure right out of the box.
However, say I have another URL named www.MyApp.com that I want to point (redirect) to https://MyApp.azurewebsite.net. Do I have to secure www.MyApp.com with a certificate?
Do I have to secure www.MyApp.com with a certificate?
Yes, we could get more detail info from the official document .
To secure your custom domain name with HTTPS, you bind a custom SSL certificate to that custom domain in Azure.
Before binding a custom certificate, we need to do the following:
Configure the custom domain - App Service only allows adding a certificate for a domain name that's already configured in your app. For instructions, see Map a custom domain name to an Azure app.
Scale up to Basic tier or higher App Service plans in lower pricing tiers don't support custom SSL certificates. For instructions, see Scale up an app in Azure.
Get an SSL certificate - If you do not already have one, you need to get one from a trusted certificate authority (CA).
Yes, if you use a custom host name, then you will need to have a certificate for it. There is really no way around this, based on how SSL works.
I have a simple static site which I provide through Amazon's Cloudfront. There is nothing of importance on there so it does not need HTTPS, furthermore I don't want to go through the hassle and cost of setting up an SSL certificate for my site, and I'm happy if requests are sent through HTTPS are met with a service unavailable or whatever other error message would be considered appropriate. Instead, Cloudfront attempts to serve the HTTPS pages using its own certificate and so flags the site up in the browser as 'untrusted' due to the certificate/domain name mismatch.
Is there some way to disable HTTPS entirely in Cloudfront, or some other way of gracefully falling back to HTTP whilst still using Cloudfront?
I've had the same problem.
Amazon now offers SSL certificates free of charge with following restrictions:
You can only use them in CloudFront or ELB.
Browsers which don't have Server Name Indication support won't render your site correctly.
In my case, I just used it even though I never need it. It is much better than having "Untrusted Connection" on the browser.
I couldn't find any mechanism to graceful fail or to block HTTPS completely.
See : http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/SecureConnections.html#CNAMEsAndHTTPS
For those who are using AWS web console to setup their cloudfront, follow this path to change the "Viewer protocol policy":
AWS Web Console > Cloudfront > Cloudfront Distributions > [Select your distribution] > Behaviors tab > [Select your cache behavior] > Edit > Viewer Protocol Policy > Set "HTTP and HTTPS"
You can specify independently, for each CloudFront origin, if it should use HTTP and HTTPS or only HTTP using the Origin Protocol Policy setting.
Protocols
CloudFront forwards HTTP or HTTPS requests to the origin server based
on the following:
The protocol of the request that the end user sends to CloudFront,
either HTTP or HTTPS.
The value of the Origin Protocol Policy field in the CloudFront
console or, if you're using the CloudFront API, the
OriginProtocolPolicy element in the DistributionConfig complex type.
In the CloudFront console, the options are HTTP Only and Match Viewer.
If you specify HTTP Only, CloudFront forwards requests to the origin
server using only the HTTP protocol, regardless of the protocol in the
end-user request.

Please notice that in case you wish to add an alternate domain name to a distribution:
It seems that since this release (Apr 8, 2019) when you add an alternate domain name to a distribution, you must also attach a SSL/TLS certificate to that distribution that covers the alternate domain name.
So in that case you can't disable HTTPS.
(*) Note: I personally don't see the mentioned option of HTTP Only for Origin Protocol Policy - although it is also mentioned here.
I am using an Amazon S3 bucket for uploading and downloading of data using my .NET application. Now my question is: I want to access my S3 bucket using SSL. Is it possible to implement SSL for an Amazon s3 bucket?
You can access your files via SSL like this:
https://s3.amazonaws.com/bucket_name/images/logo.gif
If you use a custom domain for your bucket, you can use S3 and CloudFront together with your own SSL certificate (or generate a free one via Amazon Certificate Manager): http://aws.amazon.com/cloudfront/custom-ssl-domains/
Custom domain SSL certs were just added today for $600/cert/month. Sign up for your invite below:
http://aws.amazon.com/cloudfront/custom-ssl-domains/
Update: SNI customer provided certs are now available for no additional charge. Much cheaper than $600/mo, and with XP nearly killed off, it should work well for most use cases.
#skalee AWS has a mechanism for achieving what the poster asks for, "implement SSL for an Amazon s3 bucket", it's called CloudFront. I'm reading "implement" as "use my SSL certs," not "just put an S on the HTTP URL which I'm sure the OP could have surmised.
Since CloudFront costs exactly the same as S3 ($0.12/GB), but has a ton of additional features around SSL AND allows you to add your own SNI cert at no additional cost, it's the obvious fix for "implementing SSL" on your domain.
I found you can do this easily via the Cloud Flare service.
Set up a bucket, enable webhosting on the bucket and point the desired CNAME to that endpoint via Cloudflare... and pay for the service of course... but $5-$20 VS $600 is much easier to stomach.

It is not possible directly with S3, but you can create a Cloud Front distribution from you bucket. Then go to certificate manager and request a certificate. Amazon gives them for free. Ones you have successfully confirmed the certification, assign it to your Cloud Front distribution. Also remember to set the rule to re-direct http to https.
I'm hosting couple of static websites on Amazon S3, like my personal website to which I have assigned the SSL certificate as they have the Cloud Front distribution.
If you really need it, consider redirections.
For example, on request to assets.my-domain.example.com/path/to/file you could perform a 301 or 302 redirection to my-bucket-name.s3.amazonaws.com/path/to/file or s3.amazonaws.com/my-bucket-name/path/to/file (please remember that in the first case my-bucket-name cannot contain any dots, otherwise it won't match *.s3.amazonaws.com, s3.amazonaws.com stated in S3 certificate).
Not tested, but I believe it would work. I see few gotchas, however.
The first one is pretty obvious, an additional request to get this redirection. And I doubt you could use redirection server provided by your domain name registrar — you'd have to upload proper certificate there somehow — so you have to use your own server for this.
The second one is that you can have urls with your domain name in page source code, but when for example user opens the pic in separate tab, then address bar will display the target url.
As mentioned before, you cannot create free certificates for S3 buckets. However, you can create Cloud Front distribution and then assign the certificate for the Cloud Front instead. You request the certificate for your domain and then just assign it to the Cloud Front distribution in the Cloud Front settings. I've used this method to serve static websites via SSL as well as serve static files.
For static website creation Amazon is the go to place. It is really affordable to get a static website with SSL.
