/**
 * <p>Verifies the hash-based message authentication code (HMAC) for a specified message, HMAC
 *       KMS key, and MAC algorithm. To verify the HMAC, <code>VerifyMac</code> computes an HMAC using
 *       the message, HMAC KMS key, and MAC algorithm that you specify, and compares the computed HMAC
 *       to the HMAC that you specify. If the HMACs are identical, the verification succeeds;
 *       otherwise, it fails. Verification indicates that the message hasn't changed since the HMAC was
 *       calculated, and the specified key was used to generate and verify the HMAC.</p>
 *          <p>HMAC KMS keys and the HMAC algorithms that KMS uses conform to industry standards
 *       defined in <a href="https://datatracker.ietf.org/doc/html/rfc2104">RFC 2104</a>.</p>
 *          <p>This operation is part of KMS support for HMAC KMS keys. For details, see
 *         <a href="https://docs.aws.amazon.com/kms/latest/developerguide/hmac.html">HMAC keys in KMS</a> in the
 *       <i>Key Management Service Developer Guide</i>.</p>
 *          <p>The KMS key that you use for this operation must be in a compatible key state. For
 * details, see <a href="https://docs.aws.amazon.com/kms/latest/developerguide/key-state.html">Key states of KMS keys</a> in the <i>Key Management Service Developer Guide</i>.</p>
 *          <p>
 *             <b>Cross-account use</b>: Yes. To perform this operation with a KMS key in a different Amazon Web Services account, specify
 *   the key ARN or alias ARN in the value of the <code>KeyId</code> parameter. </p>

 *
 * @throws {@link KMSInvalidMacException} (client fault)

 *       not match the HMAC specified in the request.</p>
 *

 * @example To verify an HMAC
