How it works
How it works
- v4 UUIDs set version=4 and RFC 4122 variant; the remaining 122 bits are random from Web Crypto.
- Collision odds are negligible for small batches; at Internet scale collisions remain extraordinarily rare.
- Not a secret: do not embed sensitive data; use proper crypto keys/tokens where required.
