Encrypt

Your DOCman files can be encrypted on your server thanks to this plugin. Encryption happens automatically on upload while decryption happens seamlessly on download.

The plugin uses Rijndael 128bit encryption algorithm. This algorithm was selected by the U.S. National Institute of Standards and Technology (NIST) as the candidate for the Advanced Encryption Standard (AES).

Encrypt must be installed on a site that does not have any existing DOCman files. Files uploaded before the plugin is enabled will not be encrypted.

Installation

1. Submit a request to receive the plugin package.
2. Install the plugin using Joomla's Extensions Manager
3. Configure and publish the plugin

Requirements

1. PHP 5.3 or newer
2. PECL mcrypt extension

Parameters

Encryption key

Your encryption key should be stored in your server as an environment variable named DOCMAN_ENCRYPTION_KEY.

If it's not found, the plugin will use a fallback encryption key. You can change this key on the plugin's settings.

Encrypting Files

To encrypt your files, just enable the Encrypt plugin then upload your files via backend or frontend. Only files that are uploaded after the plugin is enabled will be encrypted. Files uploaded via FTP will not be encrypted. 

Decrypting Files

If Encrypt is enabled and you try to download a file, that file will go through the decryption process. If you try to download a file that was not encrypted, the result will be a corrupted file. This is why you must only install Encrypt on a site that doesn't have any existing DOCman files.
