react-native-cryptopp-cpp

The fastest native implementation of Cryptopp++ functions

• Cryptopp++ is a native C++ library that provides a comprehensive suite of cryptographic algorithms and utilities for secure data processing
• react-native-cryptopp-cpp is a React Native port of the Cryptopp++ library, implemented using C++, JSI (JavaScript Interface), and Turbo Modules for maximum performance

Features

• High performance - everything is written in C++
• Uses JSI and C++ TurboModules instead of the "old" Bridge
• Super lightweight - adds only ~40KB to your app bundle
• Fully synchronous calls - no async/await, no Promises, no Bridge
• iOS, Android and Expo support

Installation

To install the library, use the following command:

yarn add react-native-cryptopp-cpp
cd ios && pod install

Usage

Import the functions you need from the library:

import { md2, md4, md5, sha256, hmacSha256, uuidv4 } from 'react-native-cryptopp-cpp';

// Example usage
const hash = md5('your input string');
const uuid = uuidv4(true); // returns UUID in uppercase

Available Functions

Function	Description	Parameters	Returns
md2	Computes MD2 hash of the input	input: string	string
md4	Computes MD4 hash of the input	input: string	string
md5	Computes MD5 hash of the input	input: string	string
sha256	Computes SHA-256 hash of the input	input: string	string
hmacSha256	Computes HMAC-SHA-256 of the input	input: string, key: string	string
uuidv4	Generates a UUID v4	isUpperCase?: boolean	string

Contributing
