generated an HMAC for a hash digest of a message, you must verify the HMAC for the same hash digest.

The AWS SDK for Java performs a Base64 encoding on this field before sending this request to the AWS service.
Users of the SDK should not perform Base64 encoding on this field.

Warning: ByteBuffers returned by the SDK are mutable. Changes to the content or position of the byte buffer will
be seen by all objects that have a reference to this object. It is recommended to call ByteBuffer.duplicate() or
ByteBuffer.asReadOnlyBuffer() before using or reading from the buffer. This behavior will be changed in a future
major version of the SDK.
