Encoding ASP / HTML

[e-XPLoDeR]

Hi.

I've some scripts that I sell them. But anyone connected my web server and he/she got all of my codes of this scripts.

Now, He/she published codes in warez sites.

I need a encoder that encodes ASP/HTML codes. I've seen it once. It was like this: For exapmle ASP code was like this:

<% i=request.querystring("data") %>

And encoded code was like:

>£#½$#{½£#{ß>£{½

So .asp file can be opened in any editor but codes appear like this. But I can't remember clearly. It can be JS or anything else.

How can I secure my codes?

Thanks.
