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)
}
}
