dterranova/crypto-bundle

This bundle provide file encryption with AES-256 Cipher The amount of memory used is independant of the file you encrypt., _(*1)

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, _(*2)

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, _(*3)

## Usage

- Encrypt a file
``` php
$cryto = $this->get("dterranova_crypto.crypto_adapter");
$crypto->encryptFile(ABSOLUTE_FILE_PATH, KEY);
