react-native-quick-crypto

⚡️ react-native-quick-crypto

A fast implementation of Node's crypto module written in C/C++ JSI.

QuickCrypto can be used as a drop-in replacement for your Web3/Crypto apps to speed up all cryptography functions.

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 31.3582738422ms

With react-native-crypto ⚡️:

Creating a Wallet took 2.47425001859ms

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

+const path = require('path');

 module.exports = {
+  resolver: {
+    extraNodeModules: {
+      crypto: path.resolve(__dirname, './node_modules/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.
