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

Install in iOS app

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)<

Install in Android app

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')
   

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

Prerequisites

• Xcode (13.3 or later should work)
• brew

Setup

sudo xcode-select --switch /Applications/Xcode.app
sudo xcodebuild -license

brew install autoconf automake cmake git pkgconfig protobuf python zlib

sudo mkdir -p /usr/local/bin
sudo ln -sf $(brew --prefix python)/bin/python3 /usr/local/bin/python

Build

1. Build binaries

rm -rf /tmp/react-native-fast-crypto
git clone git@github.com:ExodusMovement/react-native-fast-crypto.git /tmp/react-native-fast-crypto
cd /tmp/react-native-fast-crypto
yarn build

(if you're building on Apple arm, M1 & M2, you can use arch -x86_64 yarn build instead of yarn build)
