Today, we’re announcing exportable public SSL/TLS certificates from AWS Certificate Manager (ACM). Prior to this launch, you can issue your public certificates or import certificates issued by third-party certificate authorities (CAs) at no additional cost, and deploy them with integrated AWS services such as Elastic Load Balancing (ELB), Amazon CloudFront distribution, and Amazon API Gateway.

Now you can export public certificates from ACM, get access to the private keys, and use them on any workloads running on Amazon Elastic Compute Cloud (Amazon EC2) instances, containers, or on-premises hosts. The exportable public certificate are valid for 395 days. There is a charge at time of issuance, and again at time of renewal. Public certificates exported from ACM are issued by Amazon Trust Services and are widely trusted by commonly used platforms such as Apple and Microsoft and popular web browsers such as Google Chrome and Mozilla Firefox.

ACM exportable public certificates in action
To export a public certificate, you first request a new exportable public certificate. You cannot export previously created public certificates.

To get started, choose Request certificate in the ACM console and choose Enable export in the Allow export section. If you select Disable export, the private key for this certificate will be disallowed for exporting from ACM and this cannot be changed after certificate issuance.

You can also use the request-certificate command to request a public exportable certificate with Export=ENABLED option on the AWS Command Line Interface (AWS CLI).

aws acm request-certificate 
--domain-name mydomain.com 
--key-algorithm EC_Prime256v1 
--validation-method DNS 
--idempotency-token <token> 
--options 
CertificateTransparencyLoggingPreference=DISABLED 
Export=ENABLED

After you request the public certificate, you must validate your domain name to prove that you own or control the domain for which you are requesting the certificate. The certificate is typically issued within seconds after successful domain validation.

When the certificate enters status Issued, you can export your issued public certificate by choosing Export.

Export your public certificate

Enter a passphrase for encrypting the private key. You will need the passphrase later to decrypt the private key. To get the public key, Choose Generate PEM Encoding.

You can copy the PEM encoded certificate, certificate chain, and private key or download each to a separate file.

Download PEM keys

You can use the export-certificate command to export a public certificate and private key. For added security, use a file editor to store your passphrase and output keys to a file to prevent being stored in the command history.

aws acm export-certificate 
     --certificate-arn arn:aws:acm:us-east-1:<accountID>:certificate/<certificateID> 
     --passphrase fileb://path-to-passphrase-file 
     | jq -r '"(.Certificate)(.CertificateChain)(.PrivateKey)"' 
     > /tmp/export.txt

You can now use the exported public certificates for any workload that requires SSL/TLS communication such as Amazon EC2 instances. To learn more, visit Configure SSL/TLS on Amazon Linux in your EC2 instances.

Things to know
Here are a couple of things to know about exportable public certificates:

  • Key security – An administrator of your organization can set AWS IAM policies to authorize roles and users who can request exportable public certificates. ACM users who have current rights to issue a certificate will automatically get rights to issue an exportable certificate. ACM admins can also manage the certificates and take actions such as revoking or deleting the certificates. You should protect exported private keys using secure storage and access controls.
  • Revocation – You may need to revoke exportable public certificates to comply with your organization’s policies or mitigate key compromise. You can only revoke the certificates that were previously exported. The certificate revocation process is global and permanent. Once revoked, you can’t retrieve revoked certificates to reuse. To learn more, visit Revoke a public certificate in the AWS documentation.
  • Renewal – You can configure automatic renewal events for exportable public certificates by Amazon EventBridge to monitor certificate renewals and create automation to handle certificate deployment when renewals occur. To learn more, visit Using Amazon EventBridge in the AWS documentation. You can also renew these certificates on-demand. When you renew the certificates, you’re charged for a new certificate issuance. To learn more, visit Force certificate renewal in the AWS documentation.

Now available
You can now issue exportable public certificates from ACM and export the certificate with the private keys to use other compute workloads as well as ELB, Amazon CloudFront, and Amazon API Gateway.

You are subject to additional charges for an exportable public certificate when you create it with ACM. It costs $15 per fully qualified domain name and $149 per wildcard domain name. You only pay once during the lifetime of the certificate and will be charged again only when the certificate renews. To learn more, visit the AWS Certificate Manager Service Pricing page.

Give ACM exportable public certificates a try in the ACM console. To learn more, visit the ACM Documentation page and send feedback to AWS re:Post for ACM or through your usual AWS Support contacts.
