  📝 PHC string format serializer/deserializer

  <br/>

  <sub>

</p>

## Motivation
The [PHC String Format][specs:phc] is an attempt to specify a common hash string format that’s a restricted & well defined subset of the Modular Crypt Format. New hashes are strongly encouraged to adhere to the PHC specification, rather than the much looser [Modular Crypt Format][specs:mcf].

## Install

```bash
npm install --save @phc/format
```

## Usage

```js
const phc = require('@phc/format');

const phcobj = {
  id: 'pbkdf2-sha256',
  params: {i: 6400},
  salt: Buffer.from('0ZrzXitFSGltTQnBWOsdAw', 'base64'),
  hash: Buffer.from('Y11AchqV4b0sUisdZd0Xr97KWoymNE0LNNrnEgY4H9M', 'base64'),
};

const phcstr = "$pbkdf2-sha256$i=6400$0ZrzXitFSGltTQnBWOsdAw$Y11AchqV4b0sUisdZd0Xr97KWoymNE0LNNrnEgY4H9M";

phc.serialize(phcobj);
// => phcstr

phc.deserialize(phcstr);
// => phcobj
```

You can also pass an optional version parameter.

```js
const phc = require('@phc/format');

const phcobj = {
  id: 'argon2i',
  version: 19,
  params: {
    m: 120,
    t: 5000,
    p: 2
  },
  salt: Buffer.from('iHSDPHzUhPzK7rCcJgOFfg', 'base64'),
  hash: Buffer.from('J4moa2MM0/6uf3HbY2Tf5Fux8JIBTwIhmhxGRbsY14qhTltQt+Vw3b7tcJNEbk8ium8AQfZeD4tabCnNqfkD1g', 'base64'),
};

const phcstr = "$argon2i$v=19$m=120,t=5000,p=2$iHSDPHzUhPzK7rCcJgOFfg$J4moa2MM0/6uf3HbY2Tf5Fux8JIBTwIhmhxGRbsY14qhTltQt+Vw3b7tcJNEbk8ium8AQfZeD4tabCnNqfkD1g";

phc.serialize(phcobj);
// => phcstr

phc.deserialize(phcstr);
// => phcobj
```
