Good use cases

- Quick checksums and encoding during support work

- Testing regex against sample logs
Alternatives (and when to pick them)
- Desktop apps — best for heavy daily editing with lots of files

Tips for developer utilities
- Never paste production secrets into a tool you have not verified is local-only.
- Prefer SHA-256 over legacy digests for new integrity checks.
- JWT decoding is for inspection — it does not prove a token is valid.
- Minifiers here are best-effort; run your production bundler before shipping.
