UUID Generator
Create cryptographically secure UUID v4 identifiers in your browser without sending the generated values to a server. Your data is processed in your browser.
How to use
- Choose how many UUIDs to generate, from 1 to 100.
- Select Generate UUID to create the list.
- Copy one identifier or use Copy all.
How it works
The tool uses crypto.randomUUID when available and a crypto.getRandomValues fallback that sets the RFC version 4 and variant bits correctly.
Notes and limitations
- UUIDs make collisions extremely unlikely but do not replace integrity constraints in the system that stores them.
- Values are generated locally and are not stored by Noryo.
Frequently asked questions
Are the UUID values predictable?
Generation uses browser cryptographic primitives instead of Math.random.
