README

SimpleAES256 is a PHP class designed to simplify encryption and decryption using AES-256 in CBC or GCM modes.

📦 Installation

You can install the library via Packagist/Composer:

composer require mjohann/simple-aes-256

⚙️ Requirements

• PHP 8.0 or higher

🚀 Features

• Supported AES 256 CBC and AES 256 GCM:
  • encrypt
  • decrypt
  • key
  • tag

🧪 Usage Example

Example AES 256 CBC

<?php

use MJohann\Packlib\SimpleAES256;

require_once "vendor/autoload.php";

$aes = new SimpleAES256("MyPassword");
$text = "My name is Matheus";

$encrypt = $aes->encrypt_cbc($text);
$decrypt = $aes->decrypt_cbc($encrypt);

echo "Simple AES 256 CBC", PHP_EOL;
echo "Text: ", $text, PHP_EOL;
echo "Encrypt: ", $encrypt, PHP_EOL;
echo "Decrypt: ", $decrypt, PHP_EOL, PHP_EOL;

Example AES 256 GCM

<?php

use MJohann\Packlib\SimpleAES256;

require_once "vendor/autoload.php";

$aes = new SimpleAES256("MyPassword");
$text = "My name is Matheus";

$encrypt = $aes->encrypt_gcm($text);
$tag = $aes->get_tag();
$decrypt = $aes->decrypt_gcm($encrypt, $tag);

echo "Simple AES 256 GCM", PHP_EOL;
echo "Text: ", $text, PHP_EOL;
echo "Encrypt: ", $encrypt, PHP_EOL;
echo "Tag: ", $tag, PHP_EOL, PHP_EOL;
echo "Decrypt: ", $decrypt, PHP_EOL;
