Usage

Example

import { NativeModules, Platform } from 'react-native'
var Aes = NativeModules.Aes

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).then(cipher => ({
            cipher,
            iv,
        }))
    })
}

const decryptData = (encryptedData, key) => Aes.decrypt(encryptedData.cipher, key, encryptedData.iv)

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)
    }
}
