Request a private certificate in Amazon Certificate Manager

Request a private certificate (console)

  1. Sign into the Amazon Management Console and open the ACM console at https://console.amazonaws.cn/acm/home.

    Choose Request a certificate.

  2. On the Request certificate page, choose Request a private certificate and Next to continue.

  3. In the Certificate authority details section, click the Certificate authority menu and choose one of the available private CAs. If the CA is shared from another account, the ARN is prefaced by ownership information.

    Details about the CA are displayed to help you verify that you have chosen the correct one:

    • Owner

    • Type

    • Common name (CN)

    • Organization (O)

    • Organization unit (OU)

    • Country name (C)

    • State or province

    • Locality name

  4. In the Domain names section, type your domain name. You can use a fully qualified domain name (FQDN), such as www.example.com, or a bare or apex domain name such as example.com. You can also use an asterisk (*) as a wild card in the leftmost position to protect several site names in the same domain. For example, *.example.com protects corp.example.com, and images.example.com. The wild-card name will appear in the Subject field and in the Subject Alternative Name extension of the ACM certificate.

    Note

    When you request a wild-card certificate, the asterisk (*) must be in the leftmost position of the domain name and can protect only one subdomain level. For example, *.example.com can protect login.example.com, and test.example.com, but it cannot protect test.login.example.com. Also note that *.example.com protects only the subdomains of example.com, it does not protect the bare or apex domain (example.com). To protect both, see the next step

    Optionally, choose Add another name to this certificate and type the name in the text box. This is useful for authenticating both a bare or apex domain (such as example.com) and its subdomains such as *.example.com).

  5. In the Key algorithm section, chose an algorithm.

    For information to help you choose an algorithm, see Tag Amazon Certificate Manager resources.

  6. In the Tags section, you can optionally tag your certificate. Tags are key-value pairs that serve as metadata for identifying and organizing Amazon resources. For a list of ACM tag parameters and for instructions on how to add tags to certificates after creation, see Tag Amazon Certificate Manager resources.

  7. In the Certificate renewal permissions section, acknowledge the notice about certificate renewal permissions. These permissions allow automatic renewal of private PKI certificates that you sign with the selected CA. For more information, see Using a Service Linked Role with ACM.

  8. After providing all of the required information, choose Request. The console returns you to the certificate list, where you can view your new certificate.

    Note

    Depending on how you have ordered the list, a certificate you are looking for might not be immediately visible. You can click the black triangle at right to change the ordering. You can also navigate through multiple pages of certificates using the page numbers at upper-right.

Request a private certificate (CLI)

Use the request-certificate command to request a private certificate in ACM.

Note

When you request a private PKI certificate signed by a CA from Amazon Private CA, the specified signing algorithm family (RSA or ECDSA) must match the algorithm family of the CA's secret key.

aws acm request-certificate \
--domain-name www.example.com \
--idempotency-token 12563 \
--certificate-authority-arn arn:aws:acm-pca:Region:444455556666:\
certificate-authority/CA_ID

This command outputs the Amazon Resource Name (ARN) of your new private certificate.

{
    "CertificateArn": "arn:aws:acm:Region:444455556666:certificate/certificate_ID"
}

In most cases, ACM automatically attaches a service-linked role (SLR) to your account the first time that you use a shared CA. The SLR enables automatic renewal of end-entity certificates that you issue. To check whether the SLR is present, you can query IAM with the following command:

aws iam get-role --role-name AWSServiceRoleForCertificateManager

If the SLR is present, the command output should resemble the following:

{
   "Role":{
      "Path":"/aws-service-role/acm.amazonaws.com/",
      "RoleName":"AWSServiceRoleForCertificateManager",
      "RoleId":"AAAAAAA0000000BBBBBBB",
      "Arn":"arn:aws:iam::{account_no}:role/aws-service-role/acm.amazonaws.com/AWSServiceRoleForCertificateManager",
      "CreateDate":"2020-08-01T23:10:41Z",
      "AssumeRolePolicyDocument":{
         "Version":"2012-10-17",
         "Statement":[
            {
               "Effect":"Allow",
               "Principal":{
                  "Service":"acm.amazonaws.com"
               },
               "Action":"sts:AssumeRole"
            }
         ]
      },
      "Description":"SLR for ACM Service for accessing cross-account Private CA",
      "MaxSessionDuration":3600,
      "RoleLastUsed":{
         "LastUsedDate":"2020-08-01T23:11:04Z",
         "Region":"ap-southeast-1"
      }
   }
}
