Example #1 blenc_encrypt() example
<?php
/* read the PHP source code */
$source_code = file_get_contents("my_source_to_protect.php");
/* create the encrypted version */
$redistributable_key = blenc_encrypt($source_code, "my_source_encoded.php");
/* read which is the key_file */
$key_file = ini_get('blenc.key_file');
/* save the redistributable key */
file_put_contents($key_file, $redistributable_key, FILE_APPEND);
