Generates the EPCIS 2.0 event hash (hash ID) for EPCIS documents and events in XML or JSON/JSON-LD, following the GS1 CBV 2.0 and 2.1 canonical pre-hash rules. The same event in either format produces the same hash, so duplicates are easy to detect. Java library, CLI, REST API and Quarkus extension.
