Manage IAM access keys

Create an access key

To create an IAM access key, call the IamClient’s createAccessKey method with a CreateAccessKeyRequest object.

Note

You must set the region to AWS_GLOBAL for IamClient calls to work because IAM is a global service.

Imports 

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

Code 

    public static String createIAMAccessKey(IamClient iam,String user) {

        try {
            CreateAccessKeyRequest request = CreateAccessKeyRequest.builder()
                .userName(user).build();

            CreateAccessKeyResponse response = iam.createAccessKey(request);
           String keyId = response.accessKey().accessKeyId();
           return keyId;

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

See the complete example on GitHub.

List access keys

To list the access keys for a given user, create a ListAccessKeysRequest object that contains the user name to list keys for, and pass it to the IamClient’s listAccessKeys method.

Note

If you do not supply a user name to listAccessKeys, it will attempt to list access keys associated with the AWS account that signed the request.

Imports 

import software.amazon.awssdk.services.iam.model.AccessKeyMetadata;
import software.amazon.awssdk.services.iam.model.IamException;
import software.amazon.awssdk.services.iam.model.ListAccessKeysRequest;
import software.amazon.awssdk.services.iam.model.ListAccessKeysResponse;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.iam.IamClient;

Code 

    public static void listKeys( IamClient iam,String userName ){

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

            while (!done) {
                ListAccessKeysResponse response;

            if(newMarker == null) {
                ListAccessKeysRequest request = ListAccessKeysRequest.builder()
                        .userName(userName).build();
                response = iam.listAccessKeys(request);
            } else {
                ListAccessKeysRequest request = ListAccessKeysRequest.builder()
                        .userName(userName)
                        .marker(newMarker).build();
                response = iam.listAccessKeys(request);
            }

            for (AccessKeyMetadata metadata :
                    response.accessKeyMetadata()) {
                System.out.format("Retrieved access key %s",
                        metadata.accessKeyId());
            }

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

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

The results of listAccessKeys are paged (with a default maximum of 100 records per call). You can call isTruncated on the returned ListAccessKeysResponse object to see if the query returned fewer results then are available. If so, then call marker on the ListAccessKeysResponse and use it when creating a new request. Use that new request in the next invocation of listAccessKeys.

See the complete example on GitHub.

Retrieve an access key’s last used time

To get the time an access key was last used, call the IamClient’s getAccessKeyLastUsed method with the access key’s ID (which can be passed in using a GetAccessKeyLastUsedRequest object.

You can then use the returned GetAccessKeyLastUsedResponse object to retrieve the key’s last used time.

Imports 

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

Code 

    public static void getAccessKeyLastUsed(IamClient iam, String accessId ){

        try {
            GetAccessKeyLastUsedRequest request = GetAccessKeyLastUsedRequest.builder()
                    .accessKeyId(accessId).build();

            GetAccessKeyLastUsedResponse response = iam.getAccessKeyLastUsed(request);

            System.out.println("Access key was last used at: " +
                    response.accessKeyLastUsed().lastUsedDate());

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

See the complete example on GitHub.

Activate or deactivate access keys

You can activate or deactivate an access key by creating an UpdateAccessKeyRequest object, providing the access key ID, optionally the user name, and the desired status, then passing the request object to the IamClient’s updateAccessKey method.

Imports 

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

Code 

       public static void updateKey(IamClient iam, String username, String accessId, String status ) {

          try {
              if (status.toLowerCase().equalsIgnoreCase("active")) {
                  statusType = StatusType.ACTIVE;
              } else if (status.toLowerCase().equalsIgnoreCase("inactive")) {
                  statusType = StatusType.INACTIVE;
              } else {
                  statusType = StatusType.UNKNOWN_TO_SDK_VERSION;
              }
              UpdateAccessKeyRequest request = UpdateAccessKeyRequest.builder()
                .accessKeyId(accessId)
                .userName(username)
                .status(statusType)
                .build();

              iam.updateAccessKey(request);

              System.out.printf(
                "Successfully updated the status of access key %s to" +
                        "status %s for user %s", accessId, status, username);

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

See the complete example on GitHub.

Delete an access key

To permanently delete an access key, call the IamClient’s deleteKey method, providing it with a DeleteAccessKeyRequest containing the access key’s ID and username.

Note

Once deleted, a key can no longer be retrieved or used. To temporarily deactivate a key so that it can be activated again later, use updateAccessKey method instead.

Imports 

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

Code 

    public static void deleteKey(IamClient iam ,String username, String accessKey ) {

        try {
            DeleteAccessKeyRequest request = DeleteAccessKeyRequest.builder()
                    .accessKeyId(accessKey)
                    .userName(username)
                    .build();

            iam.deleteAccessKey(request);
            System.out.println("Successfully deleted access key " + accessKey +
                " from user " + username);

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