/**
 * <p>Returns information about the signing certificates associated with the specified IAM
 *             user. If none exists, the operation returns an empty list.</p>
 *         <p>Although each user is limited to a small number of signing certificates, you can still
 *             paginate the results using the <code>MaxItems</code> and <code>Marker</code>
 *             parameters.</p>
 *         <p>If the <code>UserName</code> field is not specified, the user name is determined
 *             implicitly based on the Amazon Web Services access key ID used to sign the request for this operation.
 *             This operation works for access keys under the Amazon Web Services account. Consequently, you can use
 *             this operation to manage Amazon Web Services account root user credentials even if the Amazon Web Services account
 *             has no associated users.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { IAMClient, ListSigningCertificatesCommand } from "@aws-sdk/client-iam"; // ES Modules import
 * // const { IAMClient, ListSigningCertificatesCommand } = require("@aws-sdk/client-iam"); // CommonJS import
 * const client = new IAMClient(config);
 * const command = new ListSigningCertificatesCommand(input);
 * const response = await client.send(command);
 * ```
 *
 * @see {@link ListSigningCertificatesCommandInput} for command's `input` shape.
 * @see {@link ListSigningCertificatesCommandOutput} for command's `response` shape.
 * @see {@link IAMClientResolvedConfig | config} for command's `input` shape.
