react-native-fast-crypto

This library implements fast, fully native crypto routines for React Native under iOS and Android. Fully built binaries are committed for both platforms but can also be built from scratch.

Getting started

npm install react-native-fast-crypto --save

Mostly automatic installation

react-native link react-native-fast-crypto

Manual installation

Build the C/C++ binaries from scratch (optional)

To build from scratch, run ./build-deps from a Bash prompt

iOS

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-fast-crypto and add RNFastCrypto.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNFastCrypto.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

Android

1. Open up android/app/src/main/java/[...]/MainActivity.java

• Add import com.reactlibrary.RNFastCryptoPackage; to the imports at the top of the file
• Add new RNFastCryptoPackage() to the list returned by the getPackages() method

2. Append the following lines to android/settings.gradle:

   include ':react-native-fast-crypto'
   project(':react-native-fast-crypto').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-fast-crypto/android')
   

3. Insert the following lines inside the dependencies block in android/app/build.gradle:

     compile project(':react-native-fast-crypto')
   

Usage

import crypto from 'react-native-fast-crypto';

const p = crypto.scrypt('mypassword', 'mysalt', 16384, 8, 1, 32)

p.then((result) => {
  console.log(result)
}, (error) => {
