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

$3

react-native link react-native-fast-crypto

$3

#### 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)

$3

- Xcode (13.3 or later should work)
- brew

$3

`bash
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
`

1. Build binaries

`bash
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`)
