Häufig gestellte Fragen

What is a v4 UUID?

A version 4 UUID is a 128-bit identifier generated from random numbers. The probability of a collision is astronomically low — about 1 in 2^122.

Are these UUIDs truly random?

Yes. We use crypto.randomUUID() or crypto.getRandomValues() which provide cryptographic-quality randomness.

Can I validate any UUID version?

The validator checks the format of any UUID and detects the version (v1 through v5) based on the version nibble.
