Amazon Ion Hash defines an algorithm for constructing a hash for any Ion value. For a given Ion value and consistent hash function, the algorithm guarantees hashing the value will always produce the same hash, independent of the value’s encoding (text or binary). The hash function to use is not declared by the specification—this enables the user to select the hash function most appropriate to their use case.
Ion hash is useful when determining whether two Ion values represent the same value, or determining whether an Ion value has changed. For example, a storage system might use Ion hashes to assert the integrity of its data.
