I am using react-native 0.61.5
I follow the example of the documentation

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

and I have the following error:

TypeError: Cannot read property 'randomKey' of undefined

please help

ios? android?
if you are on iOS run pod install in ios folder.

[janneman001]

Same here on ios. pod install does not help. android works fine
react-native 0.59.9

Same here "TypeError: Cannot read property 'pbkdf2' of undefined" on android, react-native 0.62.2

You can use it like this and it will work

import { NativeModules } from 'react-native'
const EncryptionHelper = {
generateKey: async (password: any, salt: any, cost: any, length: any) => await NativeModules.Aes.pbkdf2(password, salt, cost, length),
decryptData: async (encryptedData: { cipher: any; iv: any; }, key: any) => await NativeModules.Aes.decrypt(encryptedData.cipher, key, encryptedData.iv),
generateIV: async () => await NativeModules.Aes.randomKey(16),
encryptData: async (text: any, key: any, iv: any) => await NativeModules.Aes.encrypt(text, key, iv)
}
export default EncryptionHelper;
