legierski/aes

OpenSSL-compatible AES library

legierski/AES

Perform AES-256 (CBC) encryption/decryption compatible with OpenSSL, CryptoJS, Gibberish AES and possibly other libraries., _(*1)

Can be used to encrypt data in PHP and decrypt in JavaScript, or vice versa., _(*2)

Code from here: http://uk3.php.net/manual/en/function.openssl-decrypt.php#107210, _(*3)

Requirements

• PHP 5.3.3 or later
• OpenSSL extension for PHP

Installation

In composer.json:, _(*4)

``` json { "require": { "legierski/aes": "0.1.*" } }, <sub>(*5)</sub>

## Encrypting data

``` php
$aes = new \Legierski\AES\AES;

$encrypted = $aes->encrypt('Very sensitive data', 'password');

// OpenSSL will truncate rows longer than 76 characters, so let's wrap our encrypted data
$encryptedForOpenSSL = $aes->wrapForOpenSSL($encrypted);

Decrypting data

``` php $aes = new \Legierski\AES\AES;, <sub>(*6)</sub>

$decrypted = $aes->decrypt('U2FsdGVkX1+nnmEfHgoGQpwSPcT+mDZHxhr8XhEsmIvT2JAxsIzsRocO6x1PErrF', 'password');, <sub>(*7)</sub>

## Encrypting/decrypting with OpenSSL

``` bash
$ echo "Very sensitive data" | openssl enc -aes-256-cbc -a -k password

$ echo "U2FsdGVkX1+nnmEfHgoGQpwSPcT+mDZHxhr8XhEsmIvT2JAxsIzsRocO6x1PErrF" | openssl enc -aes-256-cbc -a -d -k password

Encrypting/decrypting with CryptoJS

``` js var encrypted = CryptoJS.AES.encrypt('Very sensitive data', 'password').toString();, <sub>(*8)</sub>

var decrypted = CryptoJS.AES.decrypt('U2FsdGVkX1+nnmEfHgoGQpwSPcT+mDZHxhr8XhEsmIvT2JAxsIzsRocO6x1PErrF', 'password').toString(CryptoJS.enc.Utf8);, <sub>(*9)</sub>

## Encrypting/decrypting with Gibberish AES

``` js
var encrypted = GibberishAES.enc('Very sensitive data', 'password');

var decrypted = GibberishAES.dec('U2FsdGVkX1+nnmEfHgoGQpwSPcT+mDZHxhr8XhEsmIvT2JAxsIzsRocO6x1PErrF', 'password');

Testing
