Usage

Demo project

Example

import { NativeModules, Platform } from 'react-native'
import Aes from 'react-native-aes-crypto'
const generateKey = (password, salt, cost, length) => Aes.pbkdf2(password, salt, cost, length)
const encryptData = (text, key) => {
 return Aes.randomKey(16).then(iv => {
 return Aes.encrypt(text, key, iv, 'aes-256-cbc').then(cipher => ({
 cipher,
 iv,
 }))
 })
}
const decryptData = (encryptedData, key) => Aes.decrypt(encryptedData.cipher, key, encryptedData.iv, 'aes-256-cbc')
try {
 generateKey('Arnold', 'salt', 5000, 256).then(key => {
 console.log('Key:', key)
 encryptData('These violent delights have violent ends', key)
 .then(({ cipher, iv }) => {
 console.log('Encrypted:', cipher)
 decryptData({ cipher, iv }, key)
 .then(text => {
 console.log('Decrypted:', text)
 })
 .catch(error => {
 console.log(error)
 })
 Aes.hmac256(cipher, key).then(hash => {
 console.log('HMAC', hash)
 })
 })
 .catch(error => {
 console.log(error)
 })
 })
} catch (e) {
 console.error(e)
}

Or

async function asyncDecrypt(cipher, key, iv) {
 try {
 var text = await decryptData({ cipher, iv }, key)
 console.log(text)
 return text
 } catch (e) {
 console.error(e)
 }
}
