AESCrypt-Nodejs

I struggled for two days to find a cross-platform solution on aes, and now I got it.

Other platforms

Thanks for these people's work!!!

Ruby

iOS

Android

Nodejs

The nodejs version is interoperable with the code above.

Usage

var aes = require("./aes");

var encrypted = aes.encrypt("helloworld", "123456");
console.log(encrypted);
// oJr7/fYMOVfoHulUu8n3rQ==

var decrypted = aes.decrypt(encrypted, "123456");
console.log(decrypted);
// helloworld

Background

1. aes-256-cbc in the crypto module defaults use pkcs5 padding, but on iOS, only pkcs7 is supported.
2. The initial vector is set up as blank which may be not secure, please know it.
3. The key can be any string since we do sha256 hash on it.

Thanks

The code on https://github.com/node-webot/wechat-crypto helps a lot.
