# UUID Generator

Zero-dependency UUID generator/validator (v1/v3/v4/v5).

```
python scripts/run.py gen
python scripts/run.py gen -n 5
python scripts/run.py gen -v 5 --namespace dns --name example.com
python scripts/run.py gen --upper --no-hyphens
python scripts/run.py gen --urn
printf '550e8400-e29b-41d4-a716-446655440000\nnope\n' | python scripts/run.py validate -
```

Built on stdlib `uuid`.

# UUID Generator

Generate and validate UUIDs in several versions and formats.

## When to use
The user needs one or more UUIDs (random or deterministic/namespaced) or wants
to check whether some strings are valid UUIDs and which version they are.

## How to use
Run `scripts/run.py` with a subcommand:
- `python scripts/run.py gen` — one random v4 UUID.
- `python scripts/run.py gen -n 5` — five v4 UUIDs.
- `python scripts/run.py gen -v 5 --namespace dns --name example.com` — deterministic v5.
- `python scripts/run.py gen --upper --no-hyphens` — formatting options.
- `python scripts/run.py validate ids.txt` — validate one UUID per line (or `-` for stdin).

## Pitfalls
- v3/v5 require `--name`; the same namespace+name always yields the same UUID.
- `--namespace` accepts `dns|url|oid|x500` or any UUID string as a custom namespace.
- `validate` exits non-zero if ANY line is not a valid UUID.
