/**
 * <p>Changes the status of the specified user signing certificate from active to disabled,
 *             or vice versa. This operation can be used to disable an IAM user's signing certificate
 *             as part of a certificate rotation work flow.</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. 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, UpdateSigningCertificateCommand } from "@aws-sdk/client-iam"; // ES Modules import
 * // const { IAMClient, UpdateSigningCertificateCommand } = require("@aws-sdk/client-iam"); // CommonJS import
 * const client = new IAMClient(config);
 * const command = new UpdateSigningCertificateCommand(input);
 * const response = await client.send(command);
 * ```
 *
 * @see {@link UpdateSigningCertificateCommandInput} for command's `input` shape.
 * @see {@link UpdateSigningCertificateCommandOutput} for command's `response` shape.
 * @see {@link IAMClientResolvedConfig | config} for command's `input` shape.
