Heyy!! I am planning on selling some scripts but I want to protect them from being redistributed or modified. How is it possible for me to encode or protect it? What options do I have? Any ideas?? Thanks
You can use ioncube encoding, it's pretty strong and most commercial PHP developers protect their scripts with it. You can find more information at www[dot]ioncube[dot]com
Actually, yes, you must install the decode engine. If not, it's actually very easy to decode by anyone. btw, zend and ioncube usually already installed on most server
You can encode your code cheaply using the ioncube online encoder. http://www.ioncube.com/online_encoder.php. To license your code checkout WHMCS licensing addon: http://www.whmcs.com/licensingaddon.php using this along with WHMCS allows you a fully automated process for selling and licensing your code.
If there is a will there is a way. You should use zend if you cannot afford ioncube.. put some call backs that check the development licenses.. make it harder but; as I said.. if there is a will - there is a way.
you can always decode this though i dont think its that secure http://www.whatmyipaddress.net/Base-64-Decoder.php
