Usage

Basic Usage

<?php

require 'vendor/autoload.php';

use Coreproc\CryptoGuard\CryptoGuard;

// This passphrase should be consistent and will be used as your key to encrypt/decrypt
// your string
$passphrase = 'whatever-you-want';

// Instantiate the CryptoGuard class
$cryptoGuard = new CryptoGuard($passphrase);

$stringToEncrypt = 'test';

// This will spit out the encrypted text
$encryptedText = $cryptoGuard->encrypt($stringToEncrypt);

// This should give you back the string you encrypted
echo $cryptoGuard->decrypt($encryptedText);
