Frequently Asked Questions

What is a UUID (Universally Unique Identifier)?

A UUID is a 128-bit label used for identification in computer systems. Standard UUIDs consist of 32 hexadecimal digits displayed in 5 groups separated by hyphens (8-4-4-4-12).

Is this cryptographically secure?

Yes! It prioritizes the standard browser Crypto.randomUUID() interface, which relies on the operating system’s cryptographically secure pseudo-random number generator (CSPRNG).

Can I generate thousands of keys at once?

To ensure smooth browser UI rendering and avoid interface freezes, the bulk generator is optimized up to 500 keys per click.
