// You need to define the protected directory path BEFORE including
// the class. You could move this to your config file.
// This DIR must be a FULL PATH starting from ROOT DIR
// Protect this directory from ANY WEB ACCESS with an .htaccess
// if you are using Apache Server. Must advisable.
// Use the .htaccess included in the package if you wich.
define("__SECURE_PATH__", $_SERVER['DOCUMENT_ROOT'].'/testando/efc/secured/', TRUE);
// Include the Class
require_once('efc.class.php');
// Instantiate your new class
$crypt_class = new easyfilecrypt();
/*
The $my_* vars could be retrieved from a DB like the below one:
CREATE TABLE <prefix>_efc_files (
fid int(11) unsigned NOT NULL default '0',
name varchar(50) NOT NULL default '',
type varchar(30) NOT NULL default '',
ext varchar(13) NOT NULL default '',
size int(11) unsigned NOT NULL default '0',
crc varchar(32) NOT NULL default '',
key varchar(50) NOT NULL default '',
cipher varchar(50) NOT NULL default 'twofish',
KEY fid (fid)
) TYPE=MyISAM;
You will keep values in the DB and call then through SQL.
So you could use it more like <img src="srcefc.php?fid=1" />
When $my_type is an image/* mime-type and outputs imediately the
decrypted contents.
Or more like: <a href="srcefc.php?fid=1" target="_blank">Get it!</a>
When $my_type is of another kind and starts the download of a file like
an Adobe Acrobat PDF or something else when clicked.
