react-native-libsodium
React Native bindings to Libsodium matching the libsodium-wrappers package API
Supported Platforms:
- iOS
- Android
- Web
Currently only a subset of the libsodium-wrappers exposed functionality is implemented. For missing functionality we welcome pull-requests or you can sponsor the development. Get in touch with us at hi@serenity.re
.
Installation Expo (dev-client)
This package support the Expo plugin system and can be used together with the Expo dev-client.
npm install react-native-libsodium
Extend app.config.js with the following plugins entry:
export default {
expo: {
…
plugins: [["react-native-libsodium", {}]],
}
}
Installation React Native
npm install react-native-libsodium
cd ios && pod install

React Native Web
For the web platform the constants and functions from the libsodium-wrappers
package is exposed. This also means you need to wait for the ready
Promise to be resolved before using any constant or function.
Certain constants and functions e.g. crypto_pwhash
are only available in the libsodium-wrappers-sumo
package. To load this package instead for web you can call loadSumoVersion
right after importing the package.
import { loadSumoVersion, ready } from 'react-native-libsodium';
loadSumoVersion();
