UUID v4 Generator

Data handling notes

• Generation uses `crypto.randomUUID` when available.
• Fallback generation uses `crypto.getRandomValues`, never `Math.random`.
• UUIDs are identifiers; they should not be treated as secret authentication tokens.

Before you rely on the result

This tool is intended for fast inspection and routine preparation. It can save time, but it does not replace review when the result affects production systems, security settings, business data, or legal obligations.

• Check representative inputs instead of assuming one example covers every edge case.
• Do not paste secrets, private customer data, or credentials unless you have confirmed the page processes that data locally and the use is allowed by your organization.
• Copy the output into your own workflow only after checking formatting, timezone, encoding, or syntax assumptions.
• Developer utilities are designed for quick checks. Treat generated values and decoded payloads as inputs to a review process, not as proof that a system is secure.
