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 v5
Version 5 UUIDs work similarly to Version 3, but they use the SHA-1 hashing algorithm instead of MD5. This provides stronger collision resistance while still offering deterministic generation for the same namespace/name pair. They’re defined in RFC 4122.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.
