react-native-ethers-crypto

This library supplies the bare minimum of cryptographic functions needed to speed up operations of Ethers v6 on React Native.

Installation

Install this package and its peer dependencies.

yarn add react-native-ethers-crypto
yarn add @craftzdog/react-native-buffer react-native-quick-base64

Usage

import { ethers } from 'ethers';
import { registerEthersHooks } from 'react-native-ethers-crypto';

registerEthersHooks(ethers);

// Now even 80x faster! ⚡
ethers.Wallet.createRandom();

Depending on another Android library containing libcrypto.so

react-native-ethers-crypto uses OpenSSL's libcrypto.so, which is also used by flipper. That means you can encounter an error like this while building the application:

Execution failed for task ':app:mergeDebugNativeLibs'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.MergeNativeLibsTask$MergeNativeLibsTaskWorkAction
   > 2 files found with path 'lib/arm64-v8a/libcrypto.so' from inputs:
      [...]

You can fix this error by adding the following block into your app's build.gradle.

android {
    packagingOptions {
        pickFirst 'lib/**/libcrypto.so'
    }
}

We know it's not perfect, but there's no better fix at this time.
