Encrypt a PHP script with BLENC.
string blenc_encrypt ( string $plaintext, string $encodedfile [, string $encryption_key ] )

/* 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');
