It's possible to alter encrypted data if you know something about the underlying plaintext.
var crypto = require('crypto');
var iv = Buffer.from('0000000000000000000000==', 'base64');
var key = Buffer.from('ffffffffffffffffffffffffffffffff');
// aes-256-gcm or aes-256-ctr
var encrypt = crypto.createCipheriv('aes-256-ctr', key, iv);
var decrypt = crypto.createDecipheriv('aes-256-ctr', key, iv);
var plaintext = 'hello world';
