# uuid [![Build Status](https://secure.travis-ci.org/kelektiv/node-uuid.svg?branch=master)](http://travis-ci.org/kelektiv/node-uuid) #

Simple, fast generation of [RFC4122](http://www.ietf.org/rfc/rfc4122.txt) UUIDS.

Features:

* Support for version 1, 4 and 5 UUIDs
* Support for version 1, 3, 4 and 5 UUIDs
* Cross-platform
* Uses cryptographically-strong random number APIs (when available)
* Zero-dependency, small footprint (... but not [this small](https://gist.github.com/982883))

### Version 3

```javascript
const uuidv3 = require('uuid/v3');

// Incantations
uuidv3(name, namespace);
uuidv3(name, namespace, buffer);
uuidv3(name, namespace, buffer, offset);
```

Generate and return a RFC4122 v3 UUID.

* `name` - (String | Array[]) "name" to create UUID with
* `namespace` - (String | Array[]) "namespace" UUID either as a String or Array[16] of byte values
* `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written.
* `offset` - (Number) Starting index in `buffer` at which to begin writing. Default = 0

Returns `buffer`, if specified, otherwise the string form of the UUID

Example:

```javascript
// Generate a unique namespace (typically you would do this once, outside of
// your project, then bake this value into your code)
const uuidv4 = require('uuid/v4');
const uuidv3 = require('uuid/v3');
const MY_NAMESPACE = uuidv4(); // ⇨ '029f3419-d770-48bc-8862-5efd8eef925d'

// Generate a couple namespace uuids
uuidv3('hello', MY_NAMESPACE); // ⇨ 'be216b77-2b79-3713-99af-a0add9d751f2'
