dterranova/crypto-bundle

This bundle provide file encryption with AES-256 Cipher The amount of memory used is independant of the file you encrypt.

Workflow

Encryption

The original file is read by the chunk_file_size and the encryption is done on this amount of data A folder is created in the temp_folder with the name of the original encrypted file Each encrypted part are written in this folder

Decryption

By passing the original file name to the decryptFile method, the cryptoBundle use the corresponding folder with encrypted parts of the file to rebuild the original file

Installation

• Add to your composer file

{
    "require": {
        ...
        "dterranova/crypto-bundle": "dev-master"
    }

}

• Update your vendors php composer.phar update

• Add to your AppKernel

    // app/AppKernel.php
    public function registerBundles()
    {
        return array(

        );
    }

• Add to your app/config/config.yml

# app/config/config.yml
dterranova_crypto:
    temp_folder: "%kernel.root_dir%/../web/YOUR_TEMP_FOLDER"
    chunk_file_size: 2 # The size (in Mb) of chunked files, more it is big more it will consume memory 

Usage

• Encrypt a file

$cryto = $this->get("dterranova_crypto.crypto_adapter");
$crypto->encryptFile(ABSOLUTE_FILE_PATH, KEY);

• Decrypt a file

$cryto = $this->get("dterranova_crypto.crypto_adapter");
$crypto->decryptFile(ABSOLUTE_FILE_PATH, KEY, true);  // The same absolute file path
