A JavaScript component for the Advanced Encryption Standard (AES).
npm install aesaes
===
A JavaScript component for the Advanced Encryption Standard (AES). Fully compatible with Node.js and the browser (via Browserify).
(Note, more optimizations may need to be made)
Why?
----
AES is currently one of the most popular block ciper encyrption algorithms. It is relevant to the Bitcoin private key encryption scheme BIP38.
Usage
-----
npm install --save aes
Note, that as version 0.1.x, you must be concerned with the endianess of your input data. It expects that the key is a regular JavaScript array of 4,6,8 or 32-bit unsigned values. The encrypt function is a regular JavaScript array of 4 32-bit big endian unsigned integers.
``js
var AES = require('aes')
var key = [0xffffffff,0xffffffff,0xffffffff,0xffffffff,0xffffffff,0xfffffff8];
var pt = [0x00000000,0x00000000,0x00000000,0x00000000];
var ct = [0xd241aab0,0x5a42d319,0xde81d874,0xf5c7b90d];
var aes = new AES(key);
console.dir(aes.encrypt(pt)); // => [0xd241aab0,0x5a42d319,0xde81d874,0xf5c7b90d]
console.dir(aes.decrypt(ct)); // => [0x00000000,0x00000000,0x00000000,0x00000000]

1. Clone the git repo.
2. npm install --development
#### Node.js
Make node-test
#### Browser
npm install --production selenium-standalone -g start-selenium
(source your shell or open a new one), edit file .min-wd`
start-selenium
Make browser-test
npm install -g browserify
browserify < lib/aes.js > lib/aes.bundle.js
