`js
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, 'sha256')

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

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