## Installation
|
||
|
|
|
||
|
|
```sh
|
||
|
|
npm install --save aes-decrypter
|
||
|
|
```
|
||
|
|
|
||
|
|
Also available to install globally:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
npm install --global aes-decrypter
|
||
|
|
```
|
||
|
|
|
||
|
|
The npm installation is preferred, but Bower works, too.
|
||
|
|
|
||
|
|
```sh
|
||
|
|
bower install --save aes-decrypter
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage

||
|
|
|
||

To include decrypter on your website or npm application, use any of the following methods.
|
||
|
|
```js
|
||
|
|
var Decrypter = require('aes-decrypter').Decrypter;
|
||
|
|
var fs = require('fs');
|
||
|
|
var keyContent = fs.readFileSync('something.key');
|
||
|
|
var encryptedBytes = fs.readFileSync('somithing.txt');
|
||
|
|
|
||
|
|
// keyContent is a string of the aes-keys content
|
||
|
|
var keyContent = fs.readFileSync(keyFile);
|
||
|
|
|
||
|
|
var view = new DataView(keyContent.buffer);
|
||
|
|
var key.bytes = new Uint32Array([
|
||
|
|
view.getUint32(0),
|
||
|
|
view.getUint32(4),
|
||
|
|
view.getUint32(8),
|
||
|
|
view.getUint32(12)
|
||
|
|
]);
|
||
|
|
|
||
|
|
key.iv = new Uint32Array([
|
||
|
|
0, 0, 0, 0
|
||
|
|
]);
|
||
|
|
|
||
|
|
var d = new Decrypter(
|
||
|
|
encryptedBytes,
|
||
|
|
key.bytes,
|
||
|
|
key.iv,
|
||
|
|
function(err, decryptedBytes) {
|
