Work with IAM server certificates

To enable HTTPS connections to your website or application on AWS, you need an SSL/TLS server certificate. You can use a server certificate provided by AWS Certificate Manager or one that you obtained from an external provider.

We recommend that you use ACM to provision, manage, and deploy your server certificates. With ACM you can request a certificate, deploy it to your AWS resources, and let ACM handle certificate renewals for you. Certificates provided by ACM are free. For more information about ACM, see the AWS Certificate Manager User Guide.

Get a server certificate

You can retrieve a server certificate by calling the IamClient’s getServerCertificate method, passing it a GetServerCertificateRequest with the certificate’s name.

Imports

import software.amazon.awssdk.services.iam.model.GetServerCertificateRequest;
import software.amazon.awssdk.services.iam.model.GetServerCertificateResponse;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.iam.IamClient;
import software.amazon.awssdk.services.iam.model.IamException;

Code

    public static void getCertificate(IamClient iam,String certName ) {

        try {
            GetServerCertificateRequest request = GetServerCertificateRequest.builder()
                    .serverCertificateName(certName)
                    .build();

            GetServerCertificateResponse response = iam.getServerCertificate(request);
            System.out.format("Successfully retrieved certificate with body %s",
                response.serverCertificate().certificateBody());

         } catch (IamException e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
    }

See the complete example on GitHub.

List server certificates

To list your server certificates, call the IamClient’s listServerCertificates method with a ListServerCertificatesRequest. It returns a ListServerCertificatesResponse.

Call the returned ListServerCertificateResponse object’s serverCertificateMetadataList method to get a list of ServerCertificateMetadata objects that you can use to get information about each certificate.

Results may be truncated; if the ListServerCertificateResponse object’s isTruncated method returns true, call the ListServerCertificatesResponse object’s marker method and use the marker to create a new request. Use the new request to call listServerCertificates again to get the next batch of results.

Imports

import software.amazon.awssdk.services.iam.model.IamException;
import software.amazon.awssdk.services.iam.model.ListServerCertificatesRequest;
import software.amazon.awssdk.services.iam.model.ListServerCertificatesResponse;
import software.amazon.awssdk.services.iam.model.ServerCertificateMetadata;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.iam.IamClient;

Code

    public static void listCertificates(IamClient iam) {

        try {
            boolean done = false;
            String newMarker = null;

            while(!done) {
              ListServerCertificatesResponse response;

            if (newMarker == null) {
                ListServerCertificatesRequest request =
                        ListServerCertificatesRequest.builder().build();
                response = iam.listServerCertificates(request);
            } else {
                ListServerCertificatesRequest request =
                        ListServerCertificatesRequest.builder()
                                .marker(newMarker).build();
                response = iam.listServerCertificates(request);
            }

            for(ServerCertificateMetadata metadata :
                    response.serverCertificateMetadataList()) {
                System.out.printf("Retrieved server certificate %s",
                        metadata.serverCertificateName());
            }

            if(!response.isTruncated()) {
                done = true;
            } else {
                newMarker = response.marker();
            }
        }

        } catch (IamException e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
    }

Update a server certificate

You can update a server certificate’s name or path by calling the IamClient’s updateServerCertificate method. It takes a UpdateServerCertificateRequest object set with the server certificate’s current name and either a new name or new path to use.

Imports

import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.iam.IamClient;
import software.amazon.awssdk.services.iam.model.IamException;
import software.amazon.awssdk.services.iam.model.UpdateServerCertificateRequest;
import software.amazon.awssdk.services.iam.model.UpdateServerCertificateResponse;

Code

    public static void updateCertificate(IamClient iam, String curName, String newName) {

        try {
            UpdateServerCertificateRequest request =
                UpdateServerCertificateRequest.builder()
                        .serverCertificateName(curName)
                        .newServerCertificateName(newName)
                        .build();

            UpdateServerCertificateResponse response =
                iam.updateServerCertificate(request);


            System.out.printf("Successfully updated server certificate to name %s",
                newName);

        } catch (IamException e) {
             System.err.println(e.awsErrorDetails().errorMessage());
             System.exit(1);
        }
     }

Delete a server certificate

To delete a server certificate, call the IamClient’s deleteServerCertificate method with a DeleteServerCertificateRequest containing the certificate’s name.

Imports

import software.amazon.awssdk.services.iam.model.DeleteServerCertificateRequest;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.iam.IamClient;
import software.amazon.awssdk.services.iam.model.IamException;

Code

    public static void deleteCert(IamClient iam,String certName ) {

        try {
            DeleteServerCertificateRequest request =
                DeleteServerCertificateRequest.builder()
                        .serverCertificateName(certName)
                        .build();

            iam.deleteServerCertificate(request);
            System.out.println("Successfully deleted server certificate " +
                    certName);

        } catch (IamException e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
    }
