Flysystem Encrypted Filesystem Adapter

This Flysystem adapter is a transparent decorator that encrypts/decrypts files using the Illuminate Encrypter.

Install

Via Composer

$ composer require swisnl/flysystem-encrypted

N.B. Using Flysystem 1? Please use version 1.x of this adapter.

Usage

use Illuminate\Encryption\Encrypter;
use League\Flysystem\Filesystem;
use League\Flysystem\Adapter\Local;
use Swis\Flysystem\Encrypted\EncryptedFilesystemAdapter;

// Create the adapter
$localAdapter = new Local('/path/to/root');

// Create the encrypter
$encrypter = new Encrypter('key', 'cipher');

// Decorate the adapter
$adapter = new EncryptedFilesystemAdapter($localAdapter, $encrypter);

// And use that to create the file system
$filesystem = new Filesystem($adapter);

Known limitations

1. Encrypted data is — depending on what you encrypt — roughly 30-40% bigger.
2. You can use streams with this adapter, but internally they will always be converted to a string because the entire file contents need to be encrypted/decrypted at once. This requires quite some memory, so this adapter is not recommended for large files.
