Secured swf?

[FONT=Verdana]Hello everybody,

I’ve a question.
A friend of mine tolde me that he had a program to rip an swf. Is it true that you can rip an swf?
So than it must also be possible to protect your swf ?
Because my friend also told me that he couldn’t rip some sfw’s so they had to be secured…

Can someone explane this to me?

Thx ![/FONT]
