/**
 * <p>Creates a key group that you can use with <a href="https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/PrivateContent.html">CloudFront signed URLs and signed cookies</a>.</p> <p>To create a key group, you must specify at least one public key for the key group. After you create a key group, you can reference it from one or more cache behaviors. When you reference a key group in a cache behavior, CloudFront requires signed URLs or signed cookies for all requests that match the cache behavior. The URLs or cookies must be signed with a private key whose corresponding public key is in the key group. The signed URL or cookie contains information about which public key CloudFront should use to verify the signature. For more information, see <a href="https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/PrivateContent.html">Serving private content</a> in the <i>Amazon CloudFront Developer Guide</i>.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { CloudFrontClient, CreateKeyGroupCommand } from "@aws-sdk/client-cloudfront"; // ES Modules import
 * // const { CloudFrontClient, CreateKeyGroupCommand } = require("@aws-sdk/client-cloudfront"); // CommonJS import
 * const client = new CloudFrontClient(config);
 * const input = { // CreateKeyGroupRequest
 *   KeyGroupConfig: { // KeyGroupConfig
 *     Name: "STRING_VALUE", // required
 *     Items: [ // PublicKeyIdList // required
 *       "STRING_VALUE",
 *     ],
 *     Comment: "STRING_VALUE",
 *   },
 * };
 * const command = new CreateKeyGroupCommand(input);
 * const response = await client.send(command);
 * // { // CreateKeyGroupResult
 * //   KeyGroup: { // KeyGroup
 * //     Id: "STRING_VALUE", // required
 * //     LastModifiedTime: new Date("TIMESTAMP"), // required
 * //     KeyGroupConfig: { // KeyGroupConfig
 * //       Name: "STRING_VALUE", // required
 * //       Items: [ // PublicKeyIdList // required
 * //         "STRING_VALUE",
 * //       ],
 * //       Comment: "STRING_VALUE",
 * //     },
 * //   },
 * //   Location: "STRING_VALUE",
 * //   ETag: "STRING_VALUE",
 * // };
 *
 * ```
