Use CreatePublicKey with an Amazon SDK or CLI

To create a CloudFront public key

The following example creates a CloudFront public key by providing the parameters in a JSON file named pub-key-config.json. Before you can use this command, you must have a PEM-encoded public key. For more information, see Create an RSA Key Pair in the Amazon CloudFront Developer Guide.

aws cloudfront create-public-key \
    --public-key-config file://pub-key-config.json

The file pub-key-config.json is a JSON document in the current folder that contains the following. Note that the public key is encoded in PEM format.

{
    "CallerReference": "cli-example",
    "Name": "ExampleKey",
    "EncodedKey": "-----BEGIN PUBLIC KEY-----\nMIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAxPMbCA2Ks0lnd7IR+3pw\nwd3H/7jPGwj8bLUmore7bX+oeGpZ6QmLAe/1UOWcmZX2u70dYcSIzB1ofZtcn4cJ\nenHBAzO3ohBY/L1tQGJfS2A+omnN6H16VZE1JCK8XSJyfze7MDLcUyHZETdxuvRb\nA9X343/vMAuQPnhinFJ8Wdy8YBXSPpy7r95ylUQd9LfYTBzVZYG2tSesplcOkjM3\n2Uu+oMWxQAw1NINnSLPinMVsutJy6ZqlV3McWNWe4T+STGtWhrPNqJEn45sIcCx4\nq+kGZ2NQ0FyIyT2eiLKOX5Rgb/a36E/aMk4VoDsaenBQgG7WLTnstb9sr7MIhS6A\nrwIDAQAB\n-----END PUBLIC KEY-----\n",
    "Comment": "example public key"
}

Output:

The following code example reads in a public key and uploads it to Amazon CloudFront.

import org.slf4j.LoggerFactory;
import software.amazon.awssdk.services.cloudfront.CloudFrontClient;
import software.amazon.awssdk.services.cloudfront.model.CreatePublicKeyResponse;
import software.amazon.awssdk.utils.IoUtils;

import java.io.IOException;
import java.io.InputStream;
import java.util.UUID;

public class CreatePublicKey {
    private static final Logger logger = LoggerFactory.getLogger(CreatePublicKey.class);

    public static String createPublicKey(CloudFrontClient cloudFrontClient, String publicKeyFileName) {
        try (InputStream is = CreatePublicKey.class.getClassLoader().getResourceAsStream(publicKeyFileName)) {
            String publicKeyString = IoUtils.toUtf8String(is);
            CreatePublicKeyResponse createPublicKeyResponse = cloudFrontClient
                    .createPublicKey(b -> b.publicKeyConfig(c -> c
                            .name("JavaCreatedPublicKey" + UUID.randomUUID())
                            .encodedKey(publicKeyString)
                            .callerReference(UUID.randomUUID().toString())));
            String createdPublicKeyId = createPublicKeyResponse.publicKey().id();
            logger.info("Public key created with id: [{}]", createdPublicKeyId);
            return createdPublicKeyId;

        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }
