Usage

Example

import{NativeModules,Platform}from'react-native'varAes=NativeModules.AesconstgenerateKey=(password,salt,cost,length)=>Aes.pbkdf2(password,salt,cost,length)constencrypt=(text,keyBase64)=>{returnAes.randomKey(32).then(iv=>{returnAes.encrypt(text,keyBase64,iv).then(cipher=>({
cipher,
iv,}))})}constdecrypt=(encryptedData,key)=>Aes.decrypt(encryptedData.cipher,key,encryptedData.iv)try{generateKey('Arnold','salt',5000,512).then(key=>{console.log('Key:',key)encrypt('These violent delights have violent ends',key).then(({ cipher, iv })=>{console.log('Encrypted:',cipher)decrypt({ 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)}
