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 v3
Version 3 UUIDs are derived deterministically by hashing a namespace identifier and a name string using the MD5 algorithm. The same namespace/name pair will always produce the same UUID, making them useful for stable identifiers across systems. 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.
