# @theroyalwhee0/ident

## A Unique Identifier Generator for Node
Generates unique non-predictable distributed identifiers.
It is built from a combination of a [snowflake ID](https://github.com/theroyalwhee0/snowman/), random bytes, and two partial HMACs. It is encoded using [base32h](https://base32h.github.io/).


## Installation
`npm install @theroyalwhee0/ident`

*or*

`yarn add @theroyalwhee0/ident`


## Documentation
The identGenerator() function creates a iterable sequence of tokens. The validation*Factory() functions validates a given token's structure and check the partial HMAC values.

[API Documentation](https://theroyalwhee0.github.io/ident/)


## Usage
```js
const { identGenerator, validationBothFactory } = require('@theroyalwhee0/ident');
const verifyKey = 'bird';
const signKey = 'seed';
const idents = identGenerator({
    node: 1,
    verifyKey, signKey,
  });
const validate = validationBothFactory({
    verifyKey, signKey,
  });
const { value: ident1 } = idents.next();
const { value: ident2 } = idents.next();
console.log(`${ident1}, ${ident2}`);
console.log(`${validate(ident1)}, ${validate(ident2)}`);
```
