What can you do with security & generators?

The security and generator section creates passwords, identifiers, hashes, QR codes, and barcodes directly in the browser.

Random values use the browser cryptography API, while local registries remain stored only on the current device.

Generate cryptographically random passwords and UUIDs.

Calculate file fingerprints without uploading source data.

Create downloadable QR codes and barcodes for everyday workflows.
