public class IdempotentSecureHashReceiver
extends IdempotentReceiver

IdempotentSecureHashReceiver ensures that only unique messages are received by a service. It does this by calculating the SHA-256 hash of the message itself. This provides a value with an infinitesimally small chance of a collision. This can be used to filter message duplicates. Please keep in mind that the hash is calculated over the entire byte array representing the message, so any leading or trailing spaces or extraneous bytes (like padding) can produce different hash values for the same semantic message content. Care should be taken to ensure that messages do not contain extraneous bytes. This class is useful when the message does not support unique identifiers.
