About UUID v3 Generator
UUID v3 is deterministic: the same name and namespace always produce the same UUID, computed with an MD5 hash. It is ideal for creating stable identifiers from known inputs (e.g. a URL or domain name).
Pick a standard namespace (DNS, URL, OID, X.500) or enter a custom UUID namespace. If you need a stronger hash, v5 uses SHA-1 with the same deterministic behavior.
FAQ
Is any data sent to a server?
No. UUID v3 Generator runs entirely in your browser — everything is generated locally and never uploaded to our servers.
