Free PHP Encryption tools?

[Goanna]

Anyone know of a free encryption program for PHP scripts? Something like IonCube or Zend encryption, but without the cost .

I am thinking about distributing my shopping cart but I want to try and protect it's code as best I can.

I already found a licensing system on sourceforge that I am going ti implement into it for callbacks. But I would still like to encrypt most of the function pages (I would leave the HTML based pages alone so people can alter the site).

found on the second half of this source: http://www.seocompany.ca/software/fr...-software.html

I thought your cart was based on os-commerce. wouldn't encrypting it be pointless since if asked you would have to provide the source anyway? (I just did a quick skim of the GPLv3 and found this - "One of the fundamental requirements of the GPL is that when you distribute object code to users, you must also provide them with a way to get the source.")

I really need to just sit down and read through all of these different licenses so I know their differences.

The 2nd link fourth provided looked nicer to me.

It is, but it's very heavily modified.

I know others have taken oscommerce and made changes and offered it as a commercial version (CRE loaded for isntance, they have a free version and a few paid versions).

I will have to look into it some more. Perhaps I cant encrypt everything, but I should be able to encrypt the changes I have made on my own.

Fourth, thanks for the link. I am going to look those over now.
EDIT: Looks like you could actually use both programs together. You can use PHP Obfuscator along with an encoder/cache program. But the MMCache program does require a server install and it's not as popular as say Zend Encoder, so it would be a bit of a pain for customers to install it.

But, for another project I am working on, a community site that I do not intend on distributing, it might be worth doing just for security purposes.

I was under the impression that Zend Encoder required a server install of Zend Optimizer anyway.

Yeah, I meant to say Zend Optimizer, which is the decoder for Zend Encryption. Zend Optimizer is on alot of servers nowaday by default. Ioncube is even on some of them by default nowadays (Although, ioncube can be installed on the user's end if the hosting company refuses to install it).

The point I was trying to make is I have never heard of Trunk MMCache being installed on a server by default when you setup a hosting account, and I doubt a hosting company would bother installing it for a single client here and there, so it wouldnt be as well suited for a commercially available script as one of the other Optimizers (Zend, ioncube).
