⚡️ react-native-quick-crypto

A fast implementation of Node's crypto module.

Unlike any other current JS-based polyfills, react-native-quick-crypto is written in C/C++ JSI and provides much greater performance - especially on mobile devices. QuickCrypto can be used as a drop-in replacement for your Web3/Crypto apps to speed up common cryptography functions.

• 🏎️ Up to 58x faster than all other solutions
• ⚡️ Lightning fast implementation with pure C++ and JSI, instead of JS
• 🧪 Well tested in JS and C++ (OpenSSL)
• 💰 Made for crypto apps and Wallets
• 🔢 Secure native compiled cryptography
• 🔁 Easy drop-in replacement for crypto-browserify or react-native-crypto

For example, creating a Wallet using ethers.js uses complex algorithms to generate a private-key/mnemonic-phrase pair:

const start = performance.now()
const wallet = ethers.Wallet.createRandom()
const end = performance.now()
console.log(`Creating a Wallet took ${end - start} ms.`)

Without react-native-crypto 🐢:

Creating a Wallet took 16862 ms

With react-native-crypto ⚡️:

Creating a Wallet took 289 ms

Installation

React Native  

yarn add react-native-quick-crypto
cd ios && pod install

Expo  

expo install react-native-quick-crypto
expo prebuild

Usage

In your babel.config.js, add a module resolver to replace crypto with react-native-quick-crypto:

+const path = require('path');

module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
  plugins: [
+   [
+     'module-resolver',
+     {
+       alias: {
+         'crypto': 'react-native-quick-crypto',
+       },
+     },
+   ],
    ...
  ],
};

Now, all imports for crypto will be resolved as react-native-quick-crypto instead.

Limitations

As the library uses JSI for synchronous native methods access, remote debugging (e.g. with Chrome) is no longer possible. Instead, you should use Flipper.
