Frequently asked questions
Which UUID version should I use?
Use v4 for general random identifiers, v7 when time ordering helps database locality, and v5 for deterministic namespace-and-name identifiers. v1, v3, and v6 are mainly for compatibility.
Do UUID v3 and v5 return the same value again?
Yes. The same version, namespace, and exact name produce the same UUID. v3 uses MD5 and v5 uses SHA-1; the two versions do not produce the same value.
Can I use a UUID as a secret token?
Treat UUIDs as identifiers, not access controls or authentication secrets. Use a dedicated cryptographic token when secrecy is required.
