UUID generator (v4)
// HOW IT WORKS
The tool generates cryptographic hashes (e.g. SHA-256) of your input and creates random UUIDs — entirely in the browser, nothing is sent anywhere.
Example
'hello' → SHA-256 2cf24dba…9824. UUID v4: 3f2504e0-4f89-41d3-9a0c-0305e82c3301.
Notes
- A hash is one-way: you cannot recover the input from it.
- UUID v4 is random; the chance of a collision is negligible in practice.
