Usage

Example

import { Platform } from 'react-native';
import Aes from 'react-native-aes-crypto'

const generateKey = (password, salt) => Aes.pbkdf2(password, salt);

const encrypt = (text, keyBase64) => {
    var ivBase64 = "base64 random 16 bytes string";
    return Aes.encrypt(text, keyBase64, ivBase64).then(cipher => ({ cipher, iv: ivBase64 }));
};

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

try {
    generateKey("Arnold", "salt").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);
            });
            
            Aes.hmac256(cipher, key).then(hash => {
                console.log("HMAC", hash);
            });
        });
    });
} catch (e) {
    console.error(e);
}

Or

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