UUID生成器
crypto.randomUUID生成1–100个UUID v4；其他UUID版本另评估。
使用步骤
如何使用
- Enter how many UUIDs you need, from 1 to 100.
- Select Generate UUIDs.
- Review and copy the generated list.
Browser cryptography
The generator uses crypto.randomUUID to create version 4 UUIDs. It does not contact a server or attempt to derive values from time, names, or a predictable counter.
A practical batch limit
The page limits each request to 100 UUIDs so the output remains easy to inspect and copy. UUIDs are identifiers, not passwords or encrypted data.
