Description

This is a fork of https://github.com/ioncube/php-openssl-cryptor git repo. This is the same code, but I rearranged it and made it into a composer package. I wanted to use it with my other composer code, and so it made sense to make this fork.

You can install this package using composer like this.

composer require hack3r3d/php-openssl-cryptor

The packagist for this library is located here.

Simple to use class for encrypting/decrypting using the PHP Openssl library.

The Cryptor class supports arbitrary encryption and key hashing algorithms, along with raw, base64 and hex encoding of the encrypted data. Static convenience methods are provided for the default of AES, but a cryptor instance can be used for more flexibility. The default uses aes-256-ctr to avoid the need for padding and the related issues. Unfortunately GCM cannot be used as the PHP openssl module does not provide a way to retrieve the GCM tag. This is proposed to be remedied in PHP 7.1 when associated data can be retrieved.

Example

use Crypto\Cryptor;

$data = 'Good things come in small packages.';
$key = '9901:io=[<>602vV03&Whb>9J&M~Oq';

$encrypted = Cryptor::Encrypt($data, $key);

echo "'$data' (" . strlen($data) . ") => '$encrypted'\n\n";

$decrypted = Cryptor::Decrypt($encrypted, $key);

echo "'$encrypted' => '$decrypted' (" . strlen($decrypted) . ")\n";
