/**
 * <p>Returns all public keys whose private keys were used to sign the digest files within the
 *          specified time range. The public key is needed to validate digest files that were signed
 *          with its corresponding private key.</p>
 *          <note>
 *             <p>CloudTrail uses different private and public key pairs per Region. Each digest
 *             file is signed with a private key unique to its Region. When you validate a digest file
 *             from a specific Region, you must look in the same Region for its corresponding public
 *             key.</p>
 *          </note>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { CloudTrailClient, ListPublicKeysCommand } from "@aws-sdk/client-cloudtrail"; // ES Modules import
 * // const { CloudTrailClient, ListPublicKeysCommand } = require("@aws-sdk/client-cloudtrail"); // CommonJS import
 * // import type { CloudTrailClientConfig } from "@aws-sdk/client-cloudtrail";
 * const config = {}; // type is CloudTrailClientConfig
 * const client = new CloudTrailClient(config);
 * const input = { // ListPublicKeysRequest
 *   StartTime: new Date("TIMESTAMP"),
 *   EndTime: new Date("TIMESTAMP"),
 *   NextToken: "STRING_VALUE",
 * };
 * const command = new ListPublicKeysCommand(input);
 * const response = await client.send(command);
 * // { // ListPublicKeysResponse
 * //   PublicKeyList: [ // PublicKeyList
 * //     { // PublicKey
 * //       Value: new Uint8Array(),
 * //       ValidityStartTime: new Date("TIMESTAMP"),
 * //       ValidityEndTime: new Date("TIMESTAMP"),
 * //       Fingerprint: "STRING_VALUE",
 * //     },
 * //   ],
 * //   NextToken: "STRING_VALUE",
 * // };
