PHP class for encrypt and decrypt data with AES algorithm

Supports

• custom iv
• auto generate iv
• encode and decode data

Requirements

PHP >= 7.1

Installation

Enter in composer.json

{
    "require": {
        "hemiframe/php-aes": "~1.2"
    }
}

or run in console: php composer.phar require hemiframe/php-aes

Example

require_once('vendor/autoload.php');

$aes = new \HemiFrame\Lib\AES();
$aes->setKey("testkey");
$aes->setData("testdata");

$ivString = $aes->generateIv();
$aes->setIv($ivString);

$encryptedString = $aes->encrypt();
$aes->setData($encryptedString);
$decryptedString = $aes->decrypt();

echo "Available methods: " . implode(",", \HemiFrame\Lib\AES::getAvailableMethods()) . "<br/><br/>" . PHP_EOL;
echo "IV string: " . $ivString . "<br/>" . PHP_EOL;
echo "Encrypted string: " . $encryptedString . "<br/>" . PHP_EOL;
