Environment Setup

Create a .env file in your project root with these variables:

ENCRYPTER_KEY=your-secret-key-here
ENCRYPTER_IV=your-iv-here

Usage

<?php

require 'vendor/autoload.php';

use Fixer112\Encrypter\Encrypter;



try {
    // Load .env (if not using Laravel, you need to load it manually)
    $dotenv = Dotenv\Dotenv::createImmutable(__DIR__);
    $dotenv->load();

    $encrypter = new Encrypter();

    //or initiate key and iv

    //$key = $iv = "password";
    //$encrypter = new Encrypter($key,$iv);

    $plaintext = "Hello, world!";
    $encrypted = $encrypter->encrypt($plaintext);
    echo "Encrypted: " . $encrypted . PHP_EOL;

    $decrypted = $encrypter->decrypt($encrypted);
    echo "Decrypted: " . $decrypted . PHP_EOL;

} catch (Exception $e) {
    echo "Error: " . $e->getMessage();
}

Notes

• This package depends on your .env file to provide ENCRYPTER_KEY and ENCRYPTER_IV.

• Make sure to keep your key and IV secret and do not commit them to public repositories.
