What is a UUID?
UUID (Universally Unique Identifier) is a 128-bit value used to identify information in computer systems. It is a standard format for creating unique identifiers, ensuring that each identifier is unique across different systems and applications. UUIDs are often used in databases, file systems, and other systems to identify and track information.
About UUID version v6
Version 6 UUIDs are a field-reordered variant of Version 1. They rearrange the timestamp bits so that UUIDs are monotonically increasing when sorted, improving index locality in databases and time-series storage. They’re defined in RFC 9562.Disclaimer: UUIDs are not cryptographically secure. If you need secure tokens, use a CSPRNG or a library designed for authentication secrets. There is no guarantee of uniqueness for UUIDs generated by this tool.
