Protect web content

Hi All,

I am a web developer and I am lately becoming fairly security conscious.

So three questions for you and any help appreciated.

1)I have my hesitations about my web code being revealed to everyone through the "view page source" feature of web browsers. Apparently the source review may reveal quite a few hints that affect security. Is there a way to prevent people from seeing this?

2)Being a web developer (especially PHP) I would like to know how I can restrict my programs to run on specific domains only. In this way if someone steals my code he can not deploy it on his server.

3)check if activeX or java is enabled before running. These two things will prevent my code from running on browsers that have not got specific features enabled (without which my web program goes mad...).

Thanks for your help all

If anything seriously impacts security, it should be run on the server, and not in the client.

As for that WebArmour stuff - I'm skeptical. They don't have a demo page there, which doesn't strike me as reliable. There's also no trial download or anything else.

It's cross-platform, which means that it's going to be JavaScript with maybe some entity-like encoding or whatever. Not very hard to crack usually. I just don't believe it. I've cracked these types of things before and they just never work.

If it's going to be readable by the browser, the HTML is going to be exposed. If it's exposed, it's cracked.

But honestly, I wouldn't worry about protecting HTML - it's just a waste of time. I don't know why you'd worry about it anyways. Nobody else does.
