Libsodium Adapter for Flysystem
===============================

[](#libsodium-adapter-for-flysystem)

Performing on-the-fly client-side encryption for safe storage of files.

On uploads, the content is encrypted using [Poly 1305](https://en.wikipedia.org/wiki/Poly1305) with a secret key and stored securely on the filesystem.

On downloads, the content is decrypted.

Installation
------------

[](#installation)

```
composer require alextartan/flysystem-libsodium-adapter
```

Usage
-----

[](#usage)

```
use AlexTartan\Flysystem\Adapter\ChunkEncryption\Libsodium;use AlexTartan\Flysystem\Adapter\EncryptionAdapterDecorator;
use League\Flysystem\Filesystem;
use League\Flysystem\Memory\MemoryAdapter;

$adapter = new MemoryAdapter();
$encryption = Libsodium::factory($encryptionKey, 4096);

$adapterDecorator = new EncryptionAdapterDecorator(
    $adapter,
    $encryption
);

$filesystem = new Filesystem($adapterDecorator);
```

**Notice**;

Due to how AwsS3 (and probably other remote adapters) handle stream uploads, I had to change the way this lib worked (versions up to `v.1.0.0`)

New releases employ a `php://temp` stream in which the encryption is done and once that finishes, the stream is sent to `writeStream`/`readStream`

Performance wise, it handles ok from what i could see.
