Nuxed Crypto

The Nuxed Crypto component provides a high-level cryptography interface that relies on libsodium for all of its underlying cryptography operations.

inspired by Halite.

Important

Although this library has developed with care, it has not been examined by security experts, there will always be a chance that we overlooked something. Please ask your favourite trusted hackers to hammer it for implementation errors and bugs before even thinking about deploying it in production.

Installation

This package can be installed with Composer.

$ composer require nuxed/crypto

Example

use namespace Nuxed\{Crypto, Filesystem};
use namespace Nuxed\Crypto\Symmetric;

<<__EntryPoint>>
async function main(): Awaitable<void> {
  // generate a key :
  $key = Symmetric\Encryption\Key::generate();
  
  // or load a stored encryption key :
  $file = new Filesystem\File('/path/to/encryption.key');
  $key = $key = Symmetric\Encryption\Key::import(
    new Crypto\HiddenString(await $file->read())
  );

  $message = new Crypto\HiddenString('Hello, World!');
  $ciphertext = Symmetric\Encryption\encrypt($message, $key);
  $plaintext = Symmetric\Encryption\decrypt($ciphertext, $key);

  print $plaintext->toString(); // Hello, World!
}
