Encryption

PHP OpenSSL/Sodium Encryption and Decryption

Latest Stable Version Total Downloads Latest Unstable Version License PHP Version Require

Requirements

  • PHP 7.4 or higher
  • MB_String extension
  • Depending on usage:
    • OpenSSL extesion
    • Sodium extension

Installation

composer require initphp/encryption

Configuration

$options = [
    'algo'      => 'SHA256',
    'cipher'    => 'AES-256-CTR',
    'key'       => null,
    'blocksize' => 16,
];
  • algo : Used by OpenSSL handler only. The algorithm to use to sign the data.
  • cipher : Used by OpenSSL handler only. The encryption algorithm that will be used to encrypt the data.
  • key : The top secret key string to use for encryption.
  • blocksize : It is used for sodium handler only. It is used in the sodium_pad() and sodium_unpad() functions.

Usage

require_once "vendor/autoload.php";
use \InitPHP\Encryption\Encrypt;

// OpenSSL Handler
/** @var $openssl \InitPHP\Encryption\HandlerInterface */
$openssl = Encrypt::use(\InitPHP\Encryption\OpenSSL::class, [
    'algo'      => 'SHA256',
    'cipher'    => 'AES-256-CTR',
    'key'       => 'TOP_Secret_Key',
]);

// Sodium Handler
/** @var $sodium \InitPHP\Encryption\HandlerInterface */
$sodium = Encrypt::use(\InitPHP\Encryption\Sodium::class, [
    'key'       => 'TOP_Secret_Key',
    'blocksize' => 16,
]);

Methods

encrypt()

public function encrypt(mixed $data, array $options = []): string;

decrypt()

public function decrypt(string $data, array $options = []): mixed;

Writing Your Own Handler

namespace App;

use \InitPHP\Encryption\{HandlerInterface, BaseHandler};

class MyHandler extends BaseHandler implements HandlerInterface
{
    public function encrypt($data, array $options = []): string
    {
        $options = $this->options($options);
        // ... process
    }

    public function decrypt($data, array $options = [])
    {
        $options = $this->options($options);
        // ... process
    }
}
use \InitPHP\Encryption\Encrypt;

$myhandler = Encrypt::use(\App\MyHandler::class);
