# Random Tools
|
||
|
||
Generate secure or reproducible random values locally in the browser.
|
||
|
||
Random Tools is a standalone local-first application in the [add·ideas Toolbox](https://git.add-ideas.de/lotobo/toolbox-portal). Inputs are processed in the browser and are not uploaded.
|
||
|
||
## Version 0.1 scope
|
||
|
||
- Unbiased local WebCrypto integers and strings plus normal-distribution samples
|
||
- Explicitly non-cryptographic, seeded deterministic generation with reproduction metadata
|
||
- Dice expressions, sampling without replacement, Fisher–Yates shuffling and passphrases
|
||
- UUIDv4, UUIDv7 and random ULID generation
|
||
- Optional RANDOM.ORG integer requests only after per-session consent
|
||
|
||
Secure local generation never falls back to the seeded or remote source. Deterministic results are reproducible but not suitable for secrets. The RANDOM.ORG workspace is the sole network-capable feature: it is not the default, requires an explicit consent checkbox, omits credentials/referrer and may still be unavailable because of browser CORS policy. See [docs/ARCHITECTURE.md](docs/ARCHITECTURE.md) and [docs/PRIVACY-SECURITY.md](docs/PRIVACY-SECURITY.md).
|
||
|
||
## Development
|
||
|
||
Requires Node.js 22 and npm 11.
|
||
|
||
```sh
|
||
npm ci
|
||
npm run check
|
||
npm run test:browser
|
||
```
|
||
|
||
## Release
|
||
|
||
`npm run release:artifact` creates a deterministic `release/rand-tools-0.1.0.zip` and checksum sidecar.
|
||
|
||
