Package Exports

react-native-cryptography

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-native-cryptography) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Getting started

$ npm install react-native-cryptography --save

Mostly automatic installation

Android:

$ react-native link react-native-cryptography

iOS: See manual installation section

Manual installation

iOS

In XCode, in the project navigator, right click <Your Target> ➜ Add Files to [your project's name]
Go to node_modules ➜ react-native-cryptography and add RNCryptography.m + RNCryptography.swift + RNCryptography-Bridging-Header.h
Modify RNCryptography-Bridging-Header.h name to <Your Target>-Bridging-Header.h
Add a Podfile in the sources root dir and add pod 'CryptoSwift' to it.
cd ios/ && pod install
Reopen xcode using your app workspace

Android

Open up android/app/src/main/java/[...]/MainActivity.java

Add import com.reactlibrary.RNCryptographyPackage; to the imports at the top of the file
Add new RNCryptographyPackage() to the list returned by the getPackages() method

Append the following lines to android/settings.gradle:

include ':react-native-cryptography'
project(':react-native-cryptography').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-cryptography/android')

Insert the following lines inside the dependencies block in android/app/build.gradle:
```
compile project(':react-native-cryptography')
```

Usage

import RNCryptography from 'react-native-cryptography';

// Advanced Encryption Standard

// For AES 128 -> 16 bytes key and iv
// For AES 192 -> 24 bytes key and iv
// For AES 256 -> 32 bytes key and iv

// AES: encrypt
RNCryptography.encryptAES(
  'Hello, I am a message that needs to be encrypted. bye',
  'keykeykeykeykeyk', // key
  'drowssapdrowssap' // iv
)
.then(value => console.log(value))
.catch(err => console.error(err));

// AES: decrypt
RNCryptography.decryptAES(

)
.then(value => console.log(value))
.catch(err => console.error(err));


// Hash

// MD5

RNCryptography.md5('string needing hash').then(digest => console.log(digest));

// SHA256

RNCryptography.sha256('string needing hash').then(digest => console.log(digest));
