FAQ
Are UUIDs cryptographically secure?
We use crypto.randomUUID() when available, otherwise crypto.getRandomValues() per RFC 4122 v4.
Will IDs collide?
Collision risk is negligible for practical use at v4 volumes.
What is bulk mode?
Bulk variant defaults to 50 IDs per generation for batch workflows.
Can I use these in production?
Yes for unique keys, but follow your system's ID strategy and storage constraints.
