introduce

@ko-developerhong/react-native-crypto-rsa The library provides RSA encryption and decryption in React Native applications, which allow you to generate public and private keys, and encrypt or decrypt messages.

Installation

npm install @ko-developerhong/react-native-crypto-rsa

iOS

1. Add the following lines to the Podfile.

   pod 'react-native-crypto-rsa', :path => '../node_modules/react-native-crypto-rsa'

2. From the terminal, go to the root directory of the project and issue the pod install command.

   cd ios
   pod install
   # OR
   npx pod-install ios

   Manual Installation

   Open Xcode, click Project Files, and add libreact-native-crypto-rsa.a to the Link Binary With Libraries section on the Build Phases tab.

Usage

Generating public and private keys

• The publicKey value is returned in the form of a pemString. `tsx import RNCryptoRsa from '@ko-developerhong/react-native-crypto-rsa';

// keySize: An integer value representing the size of the key to be generated. The default is 2048. const keySize = 2048 const { publicKey } = await RNCryptoRsa.init(keySize); const publicKeyPemString = await RNCryptoRsa.getPublicKey();

### Encrypt and decrypt messages
```tsx
import RNCryptoRsa from '@ko-developerhong/react-native-crypto-rsa';

const encryptedMessage = await RNCryptoRsa.encrypt('Hello, World!', publicKey);
const decryptedMessage = await RNCryptoRsa.decrypt(encryptedMessage); // Hello, World!

SHA512 hash generation

import RNCryptoRsa from '@ko-developerhong/react-native-crypto-rsa';

const { publicKey } = await RNCryptoRsa.init(keySize);
const sha512Text = await RNCryptoRsa.getSHA512Text(publicKey); // hashText

Precautions

RSA encryption and decryption are CPU and memory intensive, which can affect performance when handling large amounts of data. Public and private keys are critical to security, so they should be stored in a secure place and deleted if unnecessary. The public key is used to encrypt the message, and the private key is used to decrypt the encrypted message.
