use Dgcrypt\Dgcrypt;

// Initialize the Dgcrypt class with the desired encryption method
$dgcrypt = new Dgcrypt('aes-256-gcm'); // Can be 'aes-256-cbc', 'aes-256-gcm', or 'chacha20-poly1305'

// Set a secret key
$dgcrypt->setKey('your-secret key');


// Encrypt a string
$plainText = 'Hello, World!';
$encrypted = $dgcrypt->encrypt($plainText);

// Output the encrypted string
echo $encrypted;


// Decrypt the previously encrypted string
$decrypted = $dgcrypt->setCipherMethod('aes-256-cbc')->decrypt($encrypted);

// Output the decrypted string
echo $decrypted;


// Generate a secure random key
$generatedKey = $dgcrypt->generateKey();

// Output the generated key
echo $generatedKey; // Display the hexadecimal key


// Optionally, set a custom IV (12 bytes for GCM or ChaCha20, 16 bytes for CBC)
// If no IV is set, a secure random IV will be generated automatically
$dgcrypt->setIV();
