UUID Generator

A UUID is a 128-bit identifier designed to be unique without relying on a central sequential counter. Version 4 UUIDs are generated from random data and are widely used for database records, distributed systems, test fixtures, filenames, API objects, and temporary references where independent components need identifiers with an extremely low collision probability.

Generate the required amount and copy the values in the standard hyphenated format. UUIDs are identifiers, not secrets: they can appear in logs and URLs and should not replace authorization checks or access tokens. Before using them as primary keys, consider indexing, storage format, ordering, and the behavior of the specific database and framework.
