# react-native-sha256

sha256 natively for react-native

Speed is king, especially for javascript-driven applications with react-native!

This library provides native sha256-hashes for a string on both iOS and Android

natively. 

# Installation

```

yarn add react-native-sha256

react-native link

```

## Adding with CocoaPods

Add the RNSha256 pod to your list of application pods in your Podfile, using the path from the Podfile to the installed module:

```

pod 'RNSha256', :path => '../node_modules/react-native-sha256'

```

Install pods as usual:

```

pod install

```

# Usage

Import the lib into your project:

```javascript

import { sha256, sha256Bytes } from 'react-native-sha256';

```

Build a sha256-hash:

```javascript

sha256("Test").then( hash => {

    console.log(hash);

})

```

```javascript

const message = new Uint8Array(8);

const bytes = Array.from(message);

sha256Bytes(bytes).then( hash => {

    console.log(hash);

})

```

# File-Hashes

If you need to calculate SHA-256 hashes from a file, use this method of react-native-fs:
