Laravel Encrypt The AES Key With RSA Public Key

i have generated a custom AES key,i need to encrypt this AES key with RSA public key.

How can we do this in Laravel

Any suggestion will be appreciated.

$aesKey = base64_encode(Encrypter::generateKey('AES-128-CBC'));

i found one solution and seems its working

install phpseclib via composer

composer require phpseclib/phpseclib
use phpseclib\Crypt\RSA as Crypt_RSA;

$rsa = new Crypt_RSA();
$rsa->loadKey($publickey);
$rsa->setEncryptionMode(2);
$data = 'Your String';
$output = $rsa->encrypt($data);
echo base64_encode($output);
