Beginners question

I have some as3 gaming experience but have not taken the time to learn any web languages. [SIZE=1]ridiculous i know[/SIZE]

I have inserted adMob into my flash game for mobile using the following instructions
Adobe’s version

Happy to say it works great.
The swf calls the admob script on my domain. My question is should i be encrypting this in some way? Right now you can just navigate to the url and view source to get my admob publisher ID.
