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 v7
Version 7 UUIDs are designed for modern applications requiring time-ordering and scalability. They embed a Unix timestamp (to millisecond precision) in the most significant bits while filling the rest with cryptographically strong randomness. This makes them sortable by creation time and safe for distributed generation. 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.
