The instructions below will outline how to install an SSL certificate on an AWS EC2 instance.

Before You Start

Before you start, please make sure you have downloaded your certificate files. Still haven't downloaded your certificate? To get instructions for how to download your certificate (.zip), you can click here.

After downloading your certificate, you should have a ZIP containing the following certificate files:

certificate.crt
ca_bundle.crt
private.key

Upload Certificate via Management Console:

Summarizing the steps request a SSL certificate. Provide Domain Names. Select A Validation Method. Review & Confirm. Begin Validation Process. Provide Domain Names. By default AWS presents you with an input box to input exactly one domain name. However, you can actually include several domain names, and, you can use wildcards to describe.
Amazon Web Services: Create CSR and Install SSL Certificate (OpenSSL) Creating a CSR and installing your SSL certificate for Amazon Web Services (AWS) Use the instructions on this page to use OpenSSL to create your certificate signing request (CSR) and then upload and implement your SSL certificate.

Step 4: Enable HTTPS Traffic and Verify the Certificate. After you configure your web server for SSL/TLS offload with AWS CloudHSM, add your web server instance to a security group that allows inbound HTTPS traffic. This allows clients, such as web browsers, to establish an HTTPS connection with your web server.

Now that you have downloaded your certificate files, please follow the steps below to install in on your EC2 instance. In summary, you will need to upload your certificate files to IAM and allocate the certificate to your EC2 load balancer instance.

Log in to your AWS management console and navigate to the EC2 console.
Navigate to the EC2 Console.
Choose Load Balancer under the 'Network and Security' section.
Select the load balancer you would like to allocate your certificate to.
Go to the Listener tab, click on 'Edit' and then 'Add'. Choose 'HTTPS' as the protocol. Next, under SSL certificate select 'Change' and click on “Upload a new certificate to AWS Identity and Access Management (IAM).”
Now enter your certificate details: this includes a name for your certificate, your private key (private.key), the primary certificatr file (certificate.crt), and the certificate chain (ca_chain.crt) by pasting file contents into the designated areas.
Finally, click on 'Save'.

Upload Certificate via CLI:

Alternatively, you can also use the AWS command line interface (CLI) in order to upload your certificate files to IAM. To use the AWS command line interface for uploading your certificate to an EC2 instance, please follow the steps below.

Please Note In order for your upload to work, you may be required to rename your .crt files to .pem.

You can use the following command in order to upload your certificate files to IAM:

The certificate_object_name parameter above can be used to provide a name for your certificate object. Please also note that when you specify a file as a parameter (e.g. for certificate-body), file:// must be included.

IAM Upload Criteria

When uploading certificate files, IAM will verify if the following criteria are met:

Certificate files (certificate.csr and ca_bundle.crt) must be in X.509 PEM format.
The current date must be between the certificate issuance and expiration date.
The certificate and private key files should contain only a single item, not multiple items.
The private key must match the certificate.
The pivate key must start with -----BEGIN RSA PRIVATE KEY----- and end with -----END RSA PRIVATE KEY-----.
The private key must be encrypted with a password.

Congratulations, your site has now been secured using your new SSL certificate!

📅 Last Updated:March 02, 2018

It has never been easier than it is today to configure HTTPS access for our websites. What once use to be a painful task is now done in a few clicks of a button and often free.

In this article I will explain how we can configure static websites living in AWS to leverage 100% free SSL.

Prerequisites

Your static website must be hosted out of an S3 bucket. You can learn how to do so here.
To leverage AWS Certificate Manager (ACM) you must be serving your static website via CloudFront. This is easy to get setup via my guide here.

AWS Certificate Manager (ACM)

When it comes to Amazon Web Services, ACM is one of those services that few people know they can leverage. It isn't a hot service like Lambda, S3, or Rekognition. But, it is powerful and very easy to get started with. It integrates with other services like Elastic Load Balancing, API Gateway, and CloudFront.

With ACM you can request, renew, and deploy SSL/TLS certificates. These certificates are then used with ELB, API Gateway, or CloudFront. They are easy to get, 100% free, and managed by AWS. Meaning you never have to worry about a certificate expiring when using ACM.

In this post we are going to leverage ACM to get a SSL certificate for our static website domain. We will then be able to attach this certificate to our CloudFront distribution. By doing so users will be able to access our site over HTTPS.

Requesting and Approving A New SSL Certificate

Before we can begin we need to request and approve a new SSL certificate. This certificate is for the domain of our static website. To request a certificate via the AWS Console follow these steps.

Switch into the N.Virginia region in the AWS Console.
Navigate to Certificate Manager in the AWS Console.
Click Request a Certificate.
In the Domain name input enter www.your-site.com
Click Add another name to this certificate.
In the second Domain name input enter your-site.com
Click Next.
Select Email validation.
Click Review.
Click Confirm and request.

We can do all 10 of these steps with one AWS CLI call as well.

ACM then sends the domain owner, which should be you in this case, an email to approve the new certificate. This email typically has a subject line like 'Certificate approval for ...'. Click the approval link in the email.

Important NoteTo leverage our new certificate in CloudFront it must be created and approved in the us-east-1 region (N. Virginia).

Attaching A SSL Certificate To A CloudFront Distribution

With our new certificate approved and issued we can now hook it up to our static website distribution.

Navigate to CloudFront in the AWS Console.
Click the ID of our static website Distribution.
Click Edit.
Select Custom SSL Certificate.
From the dropdown select the new certificate we created.
Click Yes, Edit.

If you do not see the certificate on step five, then the certificate was likely not created in us-east-1.

Most changes made to CloudFront distribution can take a minute or two to propagate. Once the change is complete we can then access our static website via HTTPS: https://www.your-site.com.

Conclusion

Because our static website lives in a S3 bucket we can leverage other AWS services to enhance it. CloudFront provides us with a great extension point. Using it we
