react-native-crypto-aes v0.1.0

React Native AES

Currently Android only, since I don't own a Mac. Still no pbkdf2 support.

Getting started

$ npm install react-native-crypto-aes --save

Mostly automatic installation

$ react-native link react-native-crypto-aes

Manual installation

Android

1. Open up android/app/src/main/java/[...]/MainApplication.java

• Add import it.nicholasbertazzon.crypto.aes.RNCryptoAesPackage; to the imports at the top of the file
• Add new RNCryptoAesPackage() to the list returned by the getPackages() method

2. Append the following lines to android/settings.gradle:

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

3. Insert the following lines inside the dependencies block in android/app/build.gradle:

     implementation project(':react-native-crypto-aes')

Usage (API)

hashKey(params)

Hash the given key, in order to be used for encrypt and decrypt. Returns a base64 hashed key, see the example.

Params (object):

• key (required): standard utf-8 text
• algorithm: default to SHA-256

encrypt(params)

Encrypt the given text. Returns an object with the encrypted text and the initial vector, both encoded in base64, see the example.

Params (object):

• key (required) (base64)
• text (required): standard utf-8 text
• algorithm: default to AES/CBC/PKCS5Padding

decrypt(params)

Decrypt the given encrypted text. Returns the decrypted text.

Params (object):

• key (required) (base64)
• encrypted (required) (base64): the encrypted text
• iv (required) (base64): iv given by the encrypt function
• algorithm: default to AES/CBC/PKCS5Padding

Example

import AES from 'react-native-react-native-crypto-aes';

AES.hashKey({
            key: "My key"
        }).then(key => {
            AES.encrypt({
                key: key,
                text: "Text to encrypt"
            }).then(response => {
                AES.decrypt({
                    key: key,
                    iv: response.iv,
                    encrypted: response.encrypted
                }).then(text => alert(text));
            });
        });
